Abstract
It has been well known that aluminum is apt to adhere to WC-Co cemented carbide tools, when, for instance, different parts made of aluminum alloys are cold-worked using the above tools. The phenomenon was studied as a function of carbide grain size, cobalt content and surface roughness of the tools. It was found that the tendency of adhesion became larger with increasing carbide grain size, cobalt content and surface roughness. It was also found that aluminum was also apt to adhere to the other materials besides cemented carbide. The phenomena were discussed in detail from a viewpoint of the nature of aluminum showing strong deoxidation.
