The surface hardness, carburized structure and thickness of the carburized layer on the TiAl-alloy obtained through the different carburization technologies was studied. 试验研究了钛铝基合金离子渗碳后的渗层组织结构、渗碳温度和时间对渗层厚度、表面硬度的影响。
The hardmetal made by using carbon black carburized ultrafine W-Ta alloy powder shows an improvement of structure and cutting properties over the ordinary ones. 用碳黑碳化W-Ta合金粉得到了W-Ta的混合碳化物,用这种碳化物制得的硬质合金,在结构和切削性能上均较一般硬质合金优越。
There is no clear interface between carburized layer and matrix, and the transition of structure and component are homogeneous. 渗碳层与基体之间没有明显的界面,组织和成分过渡均匀。
