SLIDING COMPONENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sliding component formed of an iron alloy with a sliding coating on the surface for maintaining sliding property for a long period.

SOLUTION: A chemical conversion coating 2 and a lubricating coating 3 are laminated in sequence on the surface of the sliding component such as a seat belt latch 1 formed of an iron alloy. The lubricating coating 3 is formed of a material which is chemically stable to oil and which contains a solid lubricant, rust preventives and a binder, and it has fine cavities 4 communicated with the outside. After the lubricating coating 3 is formed, oil dipping treatment is given to the component to soak the cavities 4 with oil. The oil improves rest preventing effects to maintain the sliding property for a long period.
