| 摘 要： | 采用Ni-Cr合金粉末做钎料,利用800W YAG固体激光器,适当控制钎焊工艺,实现了金刚石与钢基体的牢固焊接.分析了钎料与金刚石之间的界面反应,探讨了钎料与金刚石界面处碳化物的形成机理,进行了磨削实验.结果表明,当激光输入焦比能为0.05～0.06 kJ/mm2时,金刚石磨粒与基体之间有着较高的结合强度,磨粒的利用率高,金刚石磨粒在整个加工过程中没有出现脱落的情况.

| Abstract: | In the present paper,through properly controlling the processing parameters,a firm bonding between diamond grain and steel substrate was realized by using a 800 W YAG Laser with powdered brazing filler metal of alloy Ni-Cr.A grinding experiment was performed.The results showed that a high-strength bonding between diamond grain and steel substrate could be achieved when laser beam energy input at per unit area(E) was 0.05~0.06 kJ/mm 2.The diamond grits were used efficiently.No diamond grains were pulled off during grinding experiment. |
