The solution …
We’ll work with you to select a coating with the proper carbide grain size. Fine carbide grains are better for abrasion resistance, but larger grains may be needed to resist impact and fatigue. Often, we select a distribution of carbide grain sizes to address your specific wear problem.
We use a series of internal wear tests to allow us to thoroughly screen our many potential wear coatings. A few coatings can then be selected for you to evaluate in your environment to determine which coating provides the best performance.
