AI Technical Summary

Technical Problem

Existing composite plating materials face limitations in achieving stable sliding properties and conductivity due to the orientation and density of graphite particles, which are often randomly oriented and unevenly distributed, leading to reduced effectiveness.

Method used

A composite plating material using spheroidized graphite particles with a curved cleavage direction, uniformly distributed at a high density, forming a metal plating layer with a surface occupancy rate of 20% or more, enhancing sliding properties and conductivity.

Benefits of technology

The spheroidized graphite particles ensure stable slidability and conductivity, maintaining performance even under wear conditions, with improved lubricity, wear resistance, and electrical connectivity.

Abstract

To provide a composite plating material excellent in slidability and conductivity by using spheroidized graphite particles.SOLUTION: A composite plating material consists of a metal plating layer including spheroidized graphite particles formed on a surface of a base material. The spheroidized graphite particles have an average particle size of 1 μm to 100 μm and a surface occupancy of 20% or more. The use of the spheroidized graphite particles can suppress orientation and enhance distribution density, and the spheroidized graphite particles almost uniformly exposed at high density from the surface improve slidability and conductivity.SELECTED DRAWING: Figure 1
