COMBINATION OF SLIDE MEMBERS

摘要

A combination of a first slide member made of ferrous material in which at least a slide surface layer thereof has a metallurgical structure having granular carbides (2) dispersed in a matrix phase (1), and a second slide member made of ferrous material in which at least a slide surface layer (5) thereof has a metallurgical structure having network-like carbides (4) dispersed in a martensite matrix phase (3). A proportion of an area occupied by the granular carbides on the slide surface of the first slide member is larger than a proportion of an area occupied by the network-like carbides on the slide surface of the second slide member, and owing to this difference in these occupied area proportions, generation of coagulative wear (scuffing) between the respective slide members can be effectively prevented, and a good anti-wear property is obtainable from viewpoints of scuffing as well as pitting.
