Abstract
Provided is a sliding component capable of obtaining a stable low-friction effect in a wide range of conditions of use. Sliding components have sliding surfaces sliding relative to each other. A base material of the sliding component is directly coated with a thin film mainly made of graphite, the sliding surface is formed by the thin film, and the thin film contains fillers with dimensions equal to or less than the thickness of the thin film.
Claims2
A sliding component having a sliding surface performing relative sliding,
- wherein a base material of the sliding component is directly coated with a thin film mainly made of graphite, the sliding surface is formed by the thin film,
- the thin film contains a filler with a dimension equal to or less than a thickness of the thin film,
- the thin film contains a high-hardness filler harder than the graphite constituting the thin film,
- the thin film contains a low-friction filler lower in coefficient of friction than the graphite constituting the thin film,
- content of the high-hardness filler contained in the thin film is between 10 wt % or more and 25 wt % or less, and
- the low-friction filler contains kaolin clay.
