补冲材料、冲压设备以及所采用的工艺过程等许多有关因素都对模具工作零件的寿命有影响。使用成份复杂的合金钢或高速钢及硬质合金来提高模具材料强度的传统方法现在受到限制,因这些材料都由稀有金属钨、钼、钛、锆、钴、钒和其他元素组成。为了提高冲模的抗磨耗强度、制定了几种模具工作零件表面的处理方法。为此使用了各种化学热处理,表面和体积塑性变形,电腐蚀炼制合金,激光热处理,以及覆盖耐磨层等方 Replenishing materials, stamping equipment and the process used by many other factors have an impact on the life of mold parts. Conventional methods to increase the strength of mold materials using complex alloy steel or high-speed steel and cemented carbide are now limited as these materials consist of the rare metals tungsten, molybdenum, titanium, zirconium, cobalt, vanadium and other elements. In order to improve the anti-wear strength of the die, developed several working parts mold surface treatment. To this end, a variety of chemical heat treatments, plastic deformation of the surface and volume, electrical erosion refining of alloys, laser heat treatment,
