The Wear Resistance of Pack-Boronizing of the Oilstone Forming Die

Abstract:

The main failure forms of oilstone forming die is serious wear on the work face, so the key point to extend the use life of die is how to control the wear. In order to improve the hardness and resistance to wear and prolong the use life of the oilstone forming die, the boronizing technology was used on the work face of the oilstone forming die. There are some of elements such as B、C、Al、Cr、Si　and Fe etc in boronizing layer, all of them change their contents during boronizing. Maximum value of microhardness of boronizing layer appears in subsurface, not in surface, and lows along depth of boronizing layer. The abrasion resistance of boronizing layer comes out maximum after quenching and tempering. After quenching and tempering, the lifetime of the oilstone forming die with boronizing is greatly improved.
