Abstract
The present invention provides a surface molybdenum-springing treatment process of piston ring, and is chracterized by that the molybdenum powder is sprayed ont he external surface of nitrated piston ring at a high speed by means of plasma or other spray-coating equipment, and deposited to form a layer of film whose thickness is 0.005-0.015 mm. Said invention can raise wear resistance of piston ring, can greatly raise its transfer efficiency.
Description
Affiliated technical field:
The present invention relates to metallic surface and handle, particularly the surperficial sprayed molybdenum of piston ring is handled.
Background technique
Current automobile, the general nitrogenation treatment technology that adopts in motorcycle stainless steel piston ring surface, after the steel piston ring via nitride is handled, surface hardness can reach more than the HV1000, wear-resisting, corrosion resistance is strengthened greatly, but meanwhile, the fragility of steel piston ring increases thereupon, and crackle appears in surface easily, and higher because of surface hardness, the friction flexibility of piston ring and cylinder liner descends.
Summary of the invention
The purpose of the invention is exactly to overcome the deficiencies in the prior art and a kind of surface hardness that can suitably reduce steel nitrogenize piston ring is provided, and can improve the surperficial sprayed molybdenum of piston ring of the friction flexibility of piston ring and cylinder liner and handle.
The object of the present invention is achieved like this: a kind of surperficial sprayed molybdenum of piston ring is handled, it is characterized in that the piston ring behind the nitriding treatment with plasma or other spraying equipment with the molybdenum powder high velocity jet to piston ring face, deposition forms the thick film of one deck 0.005～0.015mm.
Behind the stainless steel nitrogenize piston ring sprayed molybdenum, owing to increased thin film, surface hardness slightly descends.Engine operation, along with the rising of temperature, the friction factor of sprayed molybdenum layer constantly reduces, and the wear resistance of piston ring constantly strengthens, and the transmission efficiency of crankshaft-link rod improves greatly, thereby has prolonged the working life of piston ring, and environmental protection, energy-conservation.
Embodiment
After stainless steel piston ring nitrogenize operation finishes, with double-ended grinding machine to its up and down both ends of the surface carry out slightly, fine lapping, again with honing machine to its periphery carry out slightly, carefully honing, make piston ring face have higher surface finishment.With the sprayed molybdenum frock every piston ring is fixed in the plasma spraying machine spray booth then, adjusts the position of spray gun and frock, piston ring upper and lower end face, inside and outside disc are sprayed the thick film of one deck 0.01mm equably, spraying finishes to take out and gets final product.
