Experimental Study of Element Diffusion between the Material of Heavy-Duty Cemented Carbide Insert and the Material of Large Cylinder

Abstract:

Aiming at the problem of bonding breakage of cemented carbide insert in the process of heavy-duty cutting large cylinder, the experimental study of element diffusion between workpiece and insert material is done. Firstly, the conditions of insert bonding breakage are analyzed according to the heavy-duty cutting conditions of large cylinder and the material characteristics of workpiece and insert. And then, the experimental scheme of element diffusion is proposed. The element diffusion experiment is done, and the diffusion elements in the diffusion section of specimens are analyzed. At last, the species, distance and concentration of diffusion elements are analyzed. This provides a basis for further research of tool bonding breakage.
