Designed to machine hard materials such as hard steels and nickel- and cobalt-based super alloys, Greenleaf’s WG-300 whisker-reinforced ceramic inserts are said to provide wear and shock resistance at high surface speeds. Whisker reinforcement involves strengthening a hard ceramic matrix with strong, stiff, silicon-carbide crystals, commonly called whiskers. When are dispersed into a matrix of fine-grained aluminum oxide, the whiskers add tensile strength and improve the fracture toughness of the ceramic matrix.
