Slurry Erosion and Abrasion of Metal-Ceramic Coatings

Source

Four coatings, including tungsten carbide wear-resistant and cobalt-base corrosion-resistant materials, were tested for abrasion and erosion performance in silica sand and in Alundum slurries. A 1018 carbon steel sample was also tested for comparison. The abrasion tests were conducted with a wet sand rubber wheel device, whereas a slurry jet impingement apparatus was used in the erosion tests. The results revealed that the abrasive wear performance improves dramatically as the coating hardness increases. By contrast, the erosion performance was not clearly related to the hardness of the materials tested. The wear mechanisms and the suitability of the test methods to evaluate coatings are discussed.
