Abrasion Resistant Coating
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 several forms including:
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 many types of wear problems.
Common Coating Solutions from Thermach 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 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 strong replacement for 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 200C. This material is recommended for use when corrosion or chemical attack is an additional concern.
Aluminum Oxide Ceramic
Aluminum oxide ceramic, sometimes referred to as “White Alumina”, produces dense coatings which resist wear with 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 your maintenance personnel. When you use thermal spray to achieve abrasion and wear resistance, you also benefit from enhanced harness and increased ductility. This means you will avoid micro-cracking or increased surface fatigue.
