Cylindrical insert for coating interior surface of barrel in cylinder casing of internal combustion engine of car, has metallic alloy matrix e.g. metallic foam, wire mesh or sheet, that contain solid lubricant coating material

摘要

The insert (30) has a metallic alloy matrix e.g. metallic foam, metallic wire mesh or metallic sheet, containing a solid lubricant coating material. The coating material is an iron-based material containing wustite and/or magnetite, hematite, solid lubricant such as molybdenum disulfide, boron nitride or graphite or copper-based, molybdenum-based or nickel-based compounds, copper-based material such as alloy of bronze, nickel and/or chromium, and/or molybdenum based material with nickel and/or chromium. An independent claim is also included for a method for coating an interior surface of a barrel in a cylinder casing of an internal combustion engine.
