Abstract

The paper consideres the occurrence of fretting corrosion on nominally fixed surfaces of highly loaded parts of mining machines and mechanisms. The authors give examples of wear and damage of critical parts operating under fretting. The mechanisms of fretting corrosion when using wear-resistant coatings were considered. It is noted that when selecting materials of protective coatings of parts, which are heavy-mates from fretting, it is necessary to pay attention not only to their durability, but also to the shear sensitivity. The use of sufficiently thin coatings, which are convenient because they do not violate the maintainability of components and allow one to save parts being in tension during the operation in the assembly. The results of studies of a number of wear-resistant coatings are presented to reduce wear under fretting in a special unit. The authors studied the wear mechanisms of a number of thin-film coatings based on mechanical friction-brass plating, fluorocarbon polymer composition and vibration knurling, using scanning electron microscopy techniques
