Abstract: A surface of aluminum alloy or iron alloy coated, on at least a part, with a lead-free copper-based coating layer comprising, by weight, 0.2–15% bismuth, and at least one metal selected from the group consisting of 5–40% nickel, 1–20% chromium, 1–20% iron, and 1–10% cobalt, the balance being copper which is more than 55%. The surface may be of a swashplate used in swashplate type compressors.

Abstract: A swashplate type compressor having a cylinder block with cylinder bores disposed parallel to the axis of the cylinder block. A rotary shaft rotatably mounted within the cylinder block carries an aluminum or iron alloy swashplate. The swashplate is fixed in the rotary shaft and has two facial surfaces and an end surface. The swashplate has a coating of a thermoset composite material which is polymer based and includes 1-20 volume percent metal particles. The metal particles are selected from Cr, Ni, Fe, Cu, Mo, Al or a mixture of any of them or their alloys. The polymer portion of the composite comprises 3-20 volume % PTFE and resin binder therefor.
