Abstract

In various coating processes, nickel-based hard alloy powders are mainly applied either in atomized form or mechanically pulverized. The alloys have not only good corrosion resistance, due to the nickel solid solution which often contains chromium, but also high abrasion resistance and a relatively low melting point. Aside from nickel and chromium, most nickel hard alloys contain boron and silicon, and often small amounts of additional carbon and iron. Boron is very slightly soluble in nickel. The boride Ni3B forms a low melting eutectic at about 1.000°C with nickel or nickel solid solution.
