  • Method for manufacturing piston with re-molten reinforced combustion chamber throat
    Patent number: 9694450
    Abstract: A method for manufacturing a piston with a re-molten reinforced combustion chamber throat is provided. The manufacturing steps includes: a) piston rough machining: machining allowances of the combustion chamber throat and the combustion chamber bottom are 1-3 mm; b) piston washing and degreasing treatment; c) coating or spraying a surfactant on the combustion chamber throat and the combustion chamber bottom that need to be re-molten, wherein the surfactant formula comprises the components TiO2, SiO2, CuCl2 and MnCl2 that are mixed in percentage: 1-30% of TiO2, 1-30% of SiO2, 1-40% of CuCl2 and 1-50% of MnCl2; after the four components are uniformly mixed, a suspension is prepared by using acetone as a solvent a mass ratio of 1:(3-8); d) re-melting the piston by using an A-TIG welding method; and f) after re-melting, processing the piston into a finished product.
