摘要： PROBLEM TO BE SOLVED: To provide a metallic material sliding surface structure in which a cured layer is formed on a surface of a metallic material without forming a sprayed coating, and lubricant is sufficiently maintained without requiring waste liquid treatment, and provide a cylinder for an internal combustion engine and a metallic material sliding surface forming method.SOLUTION: A concave-convex shape is formed on a surface of a cylinder bore 6 of an aluminum alloy cylinder block 4 by carrying out a plasma melting and roughening process by a plasma melting device 2. Thereby a rough concave-convex shape is formed. In addition, a very hard concave-convex surface is formed by instantaneous solidification even when the sprayed coating is not formed. Then, a plateau surface forming process is carried out on a convex part by elastic honing processing on the concave-convex surface. A piston ring sliding surface formed by the above processes can obtain a sufficient scuffing property over a long period of time with not only a high Si aluminum alloy but also an aluminum alloy for die casting, and the liquid waste treatment or the like such as ECM is not required.
