Wear & Abrasion Resistant Coating

Wear and Abrasion Resistance

When identifying a coating to solve a wear or abrasion problem, it is important to understand the different types of wear mechanisms. Wear can take the form of many mechanisms, including:

  • Abrasive
  • Fretting
  • Erosive
  • Adhesive

The good news is that because thermal spray processes can work with a very wide spectrum of materials, different types of wear and abrasion resistant coatings can be used to combat any type of wear problems.

A&A Coatings | Common Coating Materials to Achieve Wear and Abrasion Resistance

Through thermal spray coating processes, you can easily achieve wear and abrasion resistance capabilities for your products. Here are the most common types of wear and abrasion resistant coatings:

  • Tungsten Carbide

Tungsten carbide is one of the most wear resistant materials which can be applied via the plasma spray or HVOF processes. Tungsten carbide coatings can achieve a hardness approaching or exceeding 70RC. Additionally, tungsten carbide can be ground and polished to a mirror finish, making it a great replacement for hard chrome plating.

  • Chrome Oxide Ceramic

The anti-galling and self-mating chrome oxide ceramic coatings are recommended for their excellent wear resistance to particle erosion, cavitation, hard surfaces and abrasive grains at all temperatures below 540C. Coatings of this material are insoluble in acids, alkalis and alcohol. When properly sealed, they are recommended for use in corrosive chemical environments in temperatures up to 175-200C. This material is recommended for use when corrosion or chemical attack is an additional concern.

  • Aluminum Oxide Ceramic

Aluminum oxide ceramic or sometimes referred to as “White Alumina” produces dense coatings which resist wear by fibers and threads, and also resist erosion in high temperatures. This material is very useful as a thermal barrier and when sealed, it is used for electrical resistance in high temperatures.

Benefits of Wear and Abrasion Resistant Coatings

Wear and abrasion resistant coatings can help industrial equipment and parts perform more efficiently and last longer. This will help to also lower parts and equipment replacement costs and make lives easier for the maintenance personnel. When you use thermal spray to achieve abrasion and wear resistance, you can also benefit from enhanced harness and increased ductility. What this means is that you will then be able to avoid situations such as micro-cracking or increased surface fatigue.
