The results of a comprehensive assessment of the quality of coatings obtained by electrospark deposition technique are presented. The assessment was performed using modern measurement instruments and dedicated software packages to determine the parameters of micro- and macro-geometry of the coated surfaces. It has been established that the main criteria for assessing the thickness of electrospark coatings, used to restore and harden parts, are the minimum depth, as well as the maximum height and peak-to-valley distance of the profile. It has been proven that the optimal ratio between the length of the bearing friction surface that receives an external load and the length of the surface covered by lubricant is at least 80 % for tribotechnical friction couples, and at least 60 % for parts with hardened surface.

介绍了电火花沉积技术获得的涂层质量的综合评估结果。使用现代测量仪器和专用软件包进行评估，以确定涂层表面的微观和宏观几何形状参数。已经确定，评估用于修复和硬化零件的电火花涂层厚度的主要标准是轮廓的最小深度、最大高度和峰谷距离。经证明，对于摩擦技术摩擦副，承受外部载荷的轴承摩擦表面的长度与润滑剂覆盖的表面的长度之间的最佳比率至少为80％，对于具有硬化表面的零件至少为60％ 。
