发明名称 Method of preparing iron-phosphate conversion surfaces
摘要 The present invention provides for forming an iron-phosphate conversion surface, or an iron-phosphate bi-metallic surface on metals, in situ, in internal combustion engines, pumps, hydraulic systems, compressors and other mechanical equipment and machinery, using the lubricating oil as the medium for bringing the phosphate and bi-metallic inorganic polymeric water complexes into contact with the metals in the machinery. The inorganic polymeric water complexes can be formed in accordance with U.S. Pat. Nos. 5,084,263 and 5,310,419 which are incorporated herein by reference. The bimetallic component can be any metal from Classes I through VIII of the Periodic Table. The phosphate and/or phosphate bi-metallic complexes are added to the lubricating oil while the engine is running. The iron-phosphate film that is formed reduces co-efficient of friction, reduces metal wear and extends engine life, increases mileage, reduces hydrocarbon emissions, and extends oil drainage intervals on all lubricated machinery and equipment.
