【Abstract】 In this paper,we study a new Ti catalytic method on nitriding and use the method to perform nitriding treatment of many kinds of materials. Experiments show that the method has many advantages. The method showsthat thickness of chemical compound is bigger,surface hardness is higher,speed of nitriding is faster and productivity is higher with respect to gas nitriding method and Salt bath nitriding method. So,it is a good method which can raise performance of tool steel and mould steel.更多还原
