Kind Code:

A1

Abstract:

A slider (1) comprising a swash plate (3) having a first sliding surface (3A), and a hemispherical shoe (4) sliding on that swash plate (3). The swash plate (3) is composed of a parent material (3B) of high strength brass containing Mn and Si, wherein micro granular Mn-Si compounds (6) are exposed to the interior and the first sliding surface (3A) of the parent material (3B). Since the swash plate (3) is etched after the parent material (3B) is cut, a large quantity of Mn-Si compound (6) is exposed to the first sliding surface (3A). A shoe (4) is composed of an iron based material and micro protrusions and recesses (4a, 4b) are formed on the second sliding surface (4A) of the shoe by laser quenching. Since a multiplicity of Mn-Si compounds (6) are exposed granularly to the first sliding surface (3A) of the swash plate (3), mutually continuous micro spaces exist at the adjacent positions and function as the circulating passage of lubricant. Consequently, wettability of lubricant to the first sliding surface (3A) is improved thus enhancing seizure resistance. Furthermore, load capacity of the second sliding surface (4A) of the shoe (4) can be enhanced because a multiplicity of micro protrusions and recesses (4a, 4b) are formed on the second sliding surface (4A) of the shoe (4) by laser quenching, and thereby abrasion resistance is improved.
