    摘要: A chemical process for treating the surface of a piston ring to reduce its surface friction includes immersing piston ring in machine oil, heating to 220-250 °C, adding the following components to form a mixture:







    alkali-metal carbonate
    0.15-0.50wt%

    alkali-metal nitrite
    0.15-0.50wt%

    alkali-metal chloride
    0.10-0.30wt%

    alkali-metal nitrate
    0.50-1.2wt%

    acidic manganese phosphate
    0.40-1.1wt%

    Ce-containing rare-earth metal powder
    0.30-0.90wt%

    machine oil
    rest,

    the contents of above components are based on the total weight of the whole solid additives and machine oil, then maintaining said temperature for 10-24 hours, cooling to 50°C and taking out the piston ring. The invention can be used to improve various piston rings of the cylinder including engines such as gasoline engine and diesel engine, as well air compressors etc. The process can obviously improve the work efficiency of the piston ring and the cylinder and prolong the operational life of the whole cylinder. It can not only save fuel but also reduce exhaust pollution from vehicles and air compressors, which results in good prospect in industry.

The invention can be used to improve the pistons and the cylinders for various engines and air compressors. It can obviously improve the work efficiency of the piston and the cylinder and prolong the operational life of the whole cylinder. It can not only save fuel but also reduce exhaust pollution from vehicles and air compressors, which results in good prospect in industry.
