Method for protecting power connected machine part pairs from friction corrosion

摘要

A method is provided for inhibiting the development of friction fatigue stress between the mating surfaces of paired machine parts, and particularly those subject to oscillatory loads. This is achieved by maintaining the mating surfaces separated by placing between them a material either of a different crystal structure than the parts separated, or a material of a greater hardness. The separating material may be in the form of a connecting element, or it may be coated onto one of the mating surfaces.
