    Abstract: PURPOSE: To provide a sintered copper based alloy product in which a solid lubricant having low adhesive properties such as PTFE and molybdenum disulfide is firmly stuck and fixed to the surface, and which has satisfactory slidability and seizure resistance even in an oil-free environment and a corrosive environment. CONSTITUTION: A sintered copper based alloy is treated with a selective chemical etching liquid, e.g., comprising one or more of compounds selected from the group consisting of peroxide, peroxo compounds, chromic acid and permanganic compounds, and further comprising one or more of compounds selected from the group consisting of phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, zircon hydrofluoric acid, titanium hydrofluoric acid, molybdic acid, tungstic acid, vanadic acid, niobic acid and organic chelating agents. Thereafter, a lubricative film is provided on the surface thereof.
