SLIDING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2024/071273
Kind Code:
A1
Abstract:
Provided is a sliding component in which a low-hardness first component and a high-hardness second component slide with a lubricant therebetween, wherein the configurational relationship between microroughness and large undulations imparted to the first component is optimized to enhance both lubricant retention and wettability, and to further improve anti-seizing properties. In the sliding component, the first component and the second component with higher hardness than the first component slide with a lubricant therebetween. The sliding component is imparted, in an area contacting the second component in the first component, with an isotropic texture in which the valley surface area is 1000 μm2/mm to 20000 μm2/mm, and the RLo (λc: 0.08 mm) is from 1% to 12%.
