Chrome Coating For Magnets

Chrome coating, also known as chrome plating, is one of the most prevalent surface preparation methods. It is used to enhance the look and longevity of items made of various materials such as metal, plastic, and wood. Their widespread use can be seen in automobile and motorbike components such as rims and ornamentation and domestic and commercial goods such as taps and appliances.

Chromium coating for neodymium magnets is a method for covering a neodymium magnet with a fine chromium film. A neodymium magnet with a gleaming surface is almost certainly chromium-plated. The primary function is to shield the neodymium magnet from rust and damage.

The most common technique is to place chromium coatings onto the surface of an object using electrocoating, a technology that employs electricity. And the chromium coatings can be as thin as 0.025 millimeters (0.001 inches).

Basics Of Chrome Coatings

One of the primary benefits of chromium plating is its rust resistance. This makes it perfect for safeguarding neodymium magnets, which degrade rapidly in a damp working setting.

It is also highly robust and resistant to wear and tear, making it ideal for purposes such as neodymium magnet spheres, which you may frequently contact to create various designs.

However, if exposed to significant hits or abrasions, chromium coating can become fragile and fracture or split.

Due to its look, longevity, and rust protection, chromium plating is an excellent option for neodymium magnets.

Applications Of Chrome Coating

Chrome coating, in addition to neodymium magnets, has a wide variety of product and industry uses due to its mix of look, longevity, and rust protection.

Some typical uses for chromium plating include:

1. Automobile and motorbike parts: rims, fenders, and ornamentation for cars, trucks, and bikes are frequently used.
2. Household equipment: It is frequently used to enhance the look and longevity of domestic appliances such as freezers, stoves, and dryers.
3. Silver plating is frequently used on industrial machinery such as conveyor belts, compressors, and valves to enhance the look and reduce wear and tear.
4. Medical equipment: Chromium plating is frequently used to enhance the longevity and stabilizability of medical tools such as scalpels and tweezers.
5. Furniture and decorative items: Chromium plating is frequently used to enhance the look and longevity of furniture and decorative items such as lights and sculptures.
6. Silver plating is frequently used to enhance athletic products’ look and longevity, such as golf equipment and snowboard sticks.
7. Silver plating is frequently used on maritime machineries, such as boat trailers and blades, to enhance their look and rust protection.

Features Of Chrome Coating

We can provide neodymium magnets with a variety of surface treatments. Some appear to be the same, but they have distinct differences worth noting. There are several essential differences between chromium plating and other kinds of compounds, such as nickel and zinc:

Its high-shine, shiny look makes it familiar for use on automobile and motorbike components and other ornamental items. It’s also worth thinking about if your neodymium magnets are purely cosmetic.
Exceptional durability and resistance to wear and strain to make it ideal for use in high-stress situations.
Corrosion resistance: It is highly rust-resistant, making it perfect for use in external and maritime settings.
It is impervious to bacteria and other pathogens, making it ideal for use on medical tools and other sterilizable apparatus.
Adhesion: Adheres well to various surfaces, including metal, plastic, and wood.

Types Of Chrome Coating Techniques

There are several types of chrome coating, including: 

Electroplated Chrome 

Electroplated chrome is a type of chrome coating applied to an object’s surface using an electrical current. Electroplated chrome is known for its high-shine appearance and good adhesion to various substrates. 

Vacuum-Deposited Chrome  

Vacuum-deposited chrome is a type of chrome coating applied to an object’s surface by means of a vacuum chamber. Vacuum-deposited chrome is known for its high-quality appearance and good adhesion to various substrates. 

Thermal Spray Chrome 

Thermal spray chrome is a type of chrome coating applied to an object’s surface using a high-velocity flame. Thermal spray chrome is known for its good adhesion and high-temperature resistance. 

PVD (Physical Vapor Deposition) Chrome 

PVD chrome is a type of chrome coating applied to an object’s surface using a physical vapor deposition process. PVD chrome is known for its high-quality appearance and good adhesion to various substrates. 

Powder-Coated Chrome 

Powder-coated chrome is a type of chrome coating applied to an object’s surface using a powder-coating process. Powder-coated chrome is known for its high-quality appearance and good adhesion to various substrates. 

The Process

Chrome coating is offered through two main processes: hexavalent chromium coating and trivalent chromium coating. 

  • Hexavalent chromium coating is a traditional form of chrome coating and is mainly used for functional purposes.
  • Trivalent chromium coating is the eco-friendly solution to the traditional chrome coating option and uses chromium sulfate or chromium chloride as crucial ingredients in replacing chromium trioxide.

Hexavalent Chromium 

Hexavalent chromium coating, which we also call hex-chrome, Cr6+, and chrome (VI) coating, uses chromium trioxide (also known as chromic anhydride) as the main ingredient.  

The hexavalent chromium coating solution is used for decorative and complex coating, along with the bright dipping of copper alloys, chromic acid anodizing, and chromate conversion coating. 

Disadvantages 

From the point of view of health, hexavalent chromium is the most toxic form of chromium. For this reason, Olsen doesn’t recommend using this coating technique.  

 

Trivalent Chromium 

Trivalent chromium coating, known as tri-chrome, Cr3+, and chrome (III) coating, uses chromium sulfate or chromium chloride as the main ingredient. 

Advantages 

The functional advantages of trivalent chromium are higher cathode efficiency and better throwing power, which means better production rates. 

From the point of view of health, trivalent chromium is intrinsically less toxic than hexavalent chromium. Because of the lower toxicity, it is not regulated as strictly, which reduces overhead costs.  

 

Decorative Vs. Hard Chrome Coating

Chrome coating is often categorized as either decorating or complex, depending on the thickness of the chromium layer it’s used to create.  

 

Decorative Chrome Coating 

Decorative chrome coating typically ranges from just 0.05 to 0.5 micrometers thick. It’s used on workpieces and objects of various materials, including aluminum, low-carbon steel, high-carbon steel, plastic, copper, and different alloys. 

  • Improved appearance: Decorative chrome coating provides an appealing shine and smooth, sleek surface. Dec decorative chrome coating can increase their perceived value when used on neodymium magnets as consumer products.
  • Corrosion resistance: Decorative chrome coating protects neodymium magnets from corrosion due to chemicals or other oxidizing agents.
  • Easy cleaning: Due to its corrosion resistance, decorative chrome coating is easy to clean with household cleaners and chemicals. Its smooth surface also does not trap dirt and dust particles, so products with decorative chrome coating can continue to shine for long-term use.
  • Some wear resistance: Decorative chrome coating can increase a product’s strength to some degree. However, it is also relatively easy to damage because it is thin.

 

Hard Chrome Coating 

Hard chrome coating is substantially thicker. It’s typically preferred because of its increased strength and durability. With greater thickness, hard chrome coating produces a solid and durable outer layer that’s naturally protected against degradation. 

  • Superior hardness: Hard chrome coating is more complex than most industrial abrasives and metallic coatings, measuring between 68 and 72 HRC. 
  • Durable thickness: Depending on the specific application, it is possible to apply hard chrome coating in various thicknesses to meet the project’s needs. Hard chrome coating between 10 and 500 micrometers will provide a hardness of about 68 to 69 HRC. It offers excellent resistance to abrasion and wears to extend component lifespan.
  • Low deposition temperature: Applying hard chrome coating at low temperatures ensures the physical and mechanical properties of the substrate remain unaffected during the coating
  • Wide range of bases: Hard chrome coating can apply to a wide range of base metals to suit various industrial applications – stainless steel, alloys of copper, aluminum, titanium, bronze, brass, and nickel. 
  • Excellent adhesion: Offering long-term durability, hard chrome coating has exceptional adherence to many substrates with minimal risk of flaking. 
  • Low friction: Hard chrome coating creates little conflict with metals, graphites, carbons, and polymers.
  • Wear and abrasion resistance: Its hardness and low friction make hard chrome coating exceptionally resistant to wear. 
  • Corrosion resistance: Hard chrome coating is a poor corrosion protector. It only gives approx—48 hours in NSST (neutral salt spray testing).

Size

When buying neodymium magnets, make sure you choose the size of magnet that fulfills your need. Osenc can manufacture the magnet as small as 0.2mm and as large as 200mm.

Grades

What does it mean by N35, N38, N42,….?

Neodymium magnets are graded by the material from which they are made of. As a rule, the higher the grade (a number following ‘N’), the stronger the magnet. Currently, the highest quality neodymium magnet available is N52. A letter observing a grade refers to the temperature rating of the interest. The interest will be standard temperature neodymium if no letter follows the rise.

Directions Of Magnetization

Neodymium magnets have corresponding magnetization directions according to their sizes and shapes. For example, cylinder and disc magnets can be diametrically and axially magnetized, and only axial magnetization is present for the neodymium sphere magnets.
