Tungsten carbide?cobalt materials are useful in a variety of extreme applications due to desirable blend properties, yet the technology has not significantly changed since their initial development 1920s. The mechanical properties this class is highly dependent on two variables, size tungsten carbide grains, and amount binder phase present final body. In study, isolated across three commercial ...

In this study, the effect of surface roughness and roughness morphology on the bond strength of WC-Co-Cr coatings has investigated. The three different surfaces morphology are use for this purpose. The first and tow samples sandblasted with alumina and silicon carbide respectively. Other sample no sandblasted before spraying process. The same WC-10Co-4Cr coating deposited on the substrates with...
