【Abstract】 The multi element Ni Cr Mo Cu surface alloy layer of matrix steel 1020 has been studied by double glow plasma surface alloying technology. The optimum technical parameters source voltage 1 050 V, cathode voltage 250 V, distance between poles 15.431 mm, pressure 35 Pa were obtained by regression analysis and non linear programming.更多还原
