摘要

研究了在12Kh18N10T不锈钢表面采用磁控沉积和悬浮喷涂两种不同成膜剂制备的二硫化钼耐磨涂层在极端条件下的摩擦学性能、结构和化学成分。按照ASTM G133标准,用直径为6.35 mm的ShKh15钢制成的球在真空中往复运动,试样温度为250℃,进行摩擦往复运动试验。测定了涂层在极端工况下的摩擦系数和寿命。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 ~ 21.8 h,磁控管沉积涂层的最大使用寿命为22.7 h。

Tribological Properties of Antifriction Molybdenum Disulfide Coatings under Extreme Conditions

Tribological Properties of Antifriction Molybdenum Disulfide Coatings under Extreme Conditions

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.
