对堆焊金属申钛的过渡系数及TiC在堆焊金属中的作用进行了研究,发现当焊条中加入一定比例的碳与稀土,作为联合脱氧来保护钛的过渡,能大幅度地提高钛的过渡系数,从而在结晶过程中形成TiC,提高了堆焊金属的硬度、耐磨性,并大大降低了堆焊焊条成本。 It is found that the transition coefficient of titanium in overlay metal and the role of TiC in overlay metal are studied. It is found that adding a certain proportion of carbon and rare earth to the electrode as a joint deoxidation to protect the transition of titanium can greatly improve the titanium Transition coefficient, which formed during the crystallization of TiC, increased hardfacing metal hardness, wear resistance, and greatly reduce the cost of surfacing electrode.
