Wear Resistant Coating

A wear resistant coating provides expert surface engineering. Our facility, Thermal Spray Technologies, specializes exclusively in the application of many kinds of coatings. These coatings include our wear resistant coating.

There are many types of wear mechanisms including adhesive, abrasive, erosive, cavitation, and fretting. In many cases, wear can occur from a combination of these mechanisms. Understanding the factors that are causing wear to occur is very important to engineering the proper wear resistant coating solution. Fortunately, with the ability of thermal spray to work with an almost limitless number of materials, a well-engineered wear resistant coating can usually be produced to solve even the most complex wear issues.

When engineering a wear resistant coating, Thermal Spray Technologies uses its strong expertise in materials engineering and its strength of understanding the processes of thermal spray. The combination of this knowledge provides application specific solutions to our customers wear problems.

Some of the more common materials Thermal Spray Technologies uses to provide wear resistant coatings include ceramics such as carbides and metal oxides. Carbide coatings are produced in the form of cermets (ceramic and metal). Metal oxides such as chromium oxide are also very hard and are very resistant to chemical attack so they can be an ideal solution when wear and corrosion are both present. Several metals and even some plastics are also used to create wear resistant coatings.

Wear resistant coatings can be deposited on several different materials using thermal spray. Almost all metals can be coated and even many heat sensitive materials such as carbon fiber composites and some plastics can be successfully coated.

Highly complex components, such as jet engine compressor blades, sometimes receive a wear resistant coating. Even simple parts such as bolts used in agricultural combines are coated with wear resistant coatings to greatly extend life of the bolts and prevent machine damage from the detachment of high speed rotating parts.
