Coating for suppressing adhesion of deposit, supercharger component having the coating, mechanical device and supercharger

摘要

The supercharger parts incorporated in the supercharger are the flow path parts (3), (5), (7) constituting the intake path through which the gas containing the lubricating oil flows in the supercharger (1), The coating (C1), (C3) covering the surface in contact with the gas containing the lubricating oil in the road parts (3), (5), (7) and containing nickel or a nickel-phosphorus alloy and particles made of polytetrafluoroethylene. And). The coatings (C1) and (C3) suppress the occurrence of deposits or adhesion by suppressing the solidification reaction of the lubricating oil and increasing the oil repellency.
