Abstract

The tribological properties under extreme conditions, structure, and chemical composition of antifriction coatings based on molybdenum disulfide deposited by magnetron deposition and suspension spraying with various types of a film former onto the surface of samples made of 12Kh18N10T stainless steel are studied. Tribological reciprocating movement tests in accordance with the ASTM G133 standard are carried out under reciprocating movement of a ball made of ShKh15 steel with a diameter of 6.35 mm in vacuum at the temperature of the samples of 250°C. The coefficient of friction and lifetime of the coatings under extreme operating conditions are determined. Suspension deposited coatings show a coefficient of friction of 0.046–0.049, and the magnetron deposited coating of 0.061. The maximum service life of the suspension deposited coatings is 19.7–21.8 h, and of the magnetron deposited coating, 22.7 h.

摘要

研究了通过磁控沉积和悬浮喷涂各种类型的成膜剂在 12Kh18N10T 不锈钢样品表面沉积基于二硫化钼的减摩涂层在极端条件下的摩擦学性能、结构和化学成分。根据ASTM G133标准的摩擦学往复运动测试是在250℃的样品温度下在真空中在直径为6.35mm的ShKh15钢制成的球的往复运动下进行的。确定了极端操作条件下涂层的摩擦系数和寿命。悬浮沉积涂层的摩擦系数为 0.046–0.049，磁控管沉积涂层的摩擦系数为 0.061。悬浮沉积涂层的最大使用寿命为19.7-21。
