A medium-P/high-P type Ni--P plating coating, the hardness of which can be furthermore enhanced by heat treating, is used for plating on the surface of a sliding member. However, its wear resistance does not arrive at the desired level. In addition, although the P content of the conventional Ni--P--B electroless plating coating is lower than that of Ni--P electroless plating coating, P considerably disordered the crystallinity of Ni crystals and hence impaired the sliding characteristics. There is provided as a Ni--P--B electroless plating coating, which can eliminate the above described problems, a plating coating containing from 0.05 to 5% by weight of P and from 0.01 to 0.05% by weight of B. Furthermore, barrel polishing, shot blasting, laser-beam irradiation, high-frequency induction heating and the like are applied to the plating coating.
A sliding member comprising:
A sliding member according to claim wherein said Ni--P--B plating coating contains at least one element selected from the group consisting of 0.1 to 1.0% by weight of Co and from 0.05 to 1.0% by weight of W.
A surface treatment method of a sliding member comprising the steps of:
A surface treatment method according to claim wherein said aluminum alloy contains at least one element selected from the group consisting of from 0.1 to 1.0% by weight of Co and from 0.05 to 1.0% by weight of W.
