在真空条件下用Ni-Cr合金做钎料进行了钎焊单层金刚石砂轮的实验研究，实现了金刚石与钢基体间的牢固化学冶金结合。通过扫描电镜X射线能谱，结合X射线衍射结构分析，发现Ni-Cr合金中的Cr原子与金刚石表面的碳原子反应生成稳定连续的Cr3C2膜，在钢基体结合界面上生成（FexCry）C，这是实现合金层与金刚石及钢基体之间都有较高结合强度的主要因素。通过磨削实验验证了金刚石确实有较高的把持强度。
Under vacuum condition, Ni-Cr alloy brazing filler metal was used to braze the single-layer diamond grinding wheel, and the solid chemical and metallurgical bonding between diamond and steel substrate was realized. By X-ray diffraction (XRD) and scanning electron microscopy (X-ray diffraction), it was found that the Cr atoms in the Ni-Cr alloy reacted with the carbon atoms on the diamond surface to form a stable and continuous Cr3C2 film. The FexCry C was formed on the steel substrate interface, This is to achieve the alloy layer and diamond and steel substrates have a high bond strength between the main factors. Through the grinding experiment to verify the diamond does have a higher holding strength.
