Communication research between working capacity of hardalloy cutting tools and fractal dimension of their wear

The results of communication research between the wear resistance of the Kapplicability hard-alloy cutting tools and the fractal dimension of the wear surface,which is formed on a back side of the cutting edge when processing the materialsshowing high adhesive activity are presented in the paper. It has been established thatthe wear resistance of tested cutting tools samples increases according to a fractaldimension increase of their wear surface

The relation between the inductive capacity of an oxide surface structure of hard alloys and their wear resistance

The purpose of this research is to determine the value of specific inductive capacity of oxide structures formed on the contact surfaces of carbide cutting tools. This paper also deals with the study of the effect of specific inductive capacity of polyoxide structures on the wear resistance of cutting tools exposed to intensive adhesive wear. It was established that the decrease of specific inductive capacity of the oxide film mass formed on the contact surfaces of a wedge leads to the increase of the wear resistance of cutting tools
