摘要： In a slide member such as a slide bearing, the invention can make a height of a bank portion around an oil keeping concave portion small, whereby it is possible to improve an initial conformability and improve an anti-seizure performance. A plurality of holes are formed on a slide surface with respect to an opposing member by a fiber laser apparatus. At this time, in the case that a height of a bank portion generated in the periphery of the concave portions in accordance with the laser processing so as to bulge from a slide surface is set to t, and a depth of the concave portions from the slide surface is set to h, an energy density of the laser beam is adjusted such that a value t is equal to or less than 3 μm, and a rate t/h is between 0.1 and 0.5.

摘要： A sliding material which is used for bearings, washers and other parts of automobiles, industrial machines, agricultural machines and the like, possesses an excellent abrasion resistance, and is useful under sever boundary lubricating conditions. The sliding material comprises a back plate (5) of a steel plate and a sinter bearing layer integrally provided on one surface of the back plate (5). A powder (2) of a hard material is dispersed in an amount of 0.5 to 20% by weight in a matrix (4) of the sinter bearing layer. The matrix (4) comprises 1 to 30% by weight of Pb and 1 to 15% by weight of Sn with the balance consisting of Cu. The powder (2) of a hard material comprises 7.5 to 9.5% by weight of Cr, 27 to 30% by weight of Mo, and 2.0 to 3.0% by weight of Si with the balance consisting of Co.
