【 摘 要 】

Roughness is an important factor in the working properties of instruments. Roughness determines such working properties as durability, wear resistance from detritions, density of combinations, chemical fortitude and appearance. A method for evaluating the roughness of wear-resistant electric-spark coatings on a metal cutting instrument and a specimen of fast-cutting steel is a complex parameter of roughness (Δ). Complex parameter of roughness (Δ) allows more accurately estimating the surface roughness after smoothing the mineral ceramics of an electrophysical coating and others types of surface treatment.
