ABSTRACT:
A cobalt base alloy includes the alloy elements of nickel, chromium, tungsten, silicon and carbon with the nickel content being at least 25 percent by weight. The cobalt base alloy is applied as a coating material for guide bars of saw chains. The alloy has a high hardness with low brittleness by means of which an improved resistance to wear is achieved.
