The effect of microporosity on the wear resistance of carbonitride thermochemical coatings

摘要

A group of steels with carbonitride coatings isstudied. The structure of carbonitride layers and theirmicroporosity are analyzed. The histograms characterizing thedistribution of geometrical parameters of coatings as a function oftheir microhardness are presented to elucidate the effect ofmicroporosity on the parameters which determine the wearresistance of the coatings.
