A study of the microtopography of the surfaces of steel samples after gas laser cutting has been carried. Profi le records of the investigated surfaces indicate the presence of two types of surface deviations from the geometric shape: waviness and roughness. At the same time, waviness is not present on all investigated surfaces. For different modes of the laser cutting process, the height and spacing parameters of roughness and waviness were determined. It is shown that the parameters of surface roughness after gas laser cutting are comparable to those of surfaces after such types of machining as turning and milling. Regression equations are obtained for some roughness parameters, which show the dependence of these parameters on the modes of the gas laser cutting process.

The improvement of cutting tools through the use of tool materials and wear-resistant coatings, which, taking into account the cutting conditions, allow to increase the wear resistance of the tool due to the formation of secondary structures during friction in the cutting zone is considered. On the basis of thermodynamics of nonequilibrium processes the model has bееn developed, allowing to predict wear resistance and others tribotechnical parametres hardloaded hightemperature interfaces.
