采用碳弧堆焊的方法,在高铬合金铸铁粉块中加入稀土及合金元素,探讨其对堆焊层耐磨性的影响.结果表明,稀土在碳孤中过渡量可观,适量的稀土及合金元素提高了堆焊层的耐磨性.
The effects of carbon and arc welding on the wear resistance of overlay were studied by adding rare earth and alloying elements into the high chromium alloy cast iron powder.The results show that rare earths have a considerable amount of rare earths Alloying elements improve the wear resistance of surfacing layer.
