介绍了一种硼化钛砂轮的研制。首先，一个理想的形状是由钛制成的。接下来，硼粉被涂在钛的表面。用激光束扫描表面，然后硼粉与钛发生化学反应，在钛表面产生硼化钛。生产的硼化钛用作砂轮。本文采用板状钛基板进行了制备硼化钛的实验。用x射线衍射检查衬底的表层，并在层中检测到硼化钛。用电子能谱仪和能谱仪检测了各层的截面。在激光扫描产生的凹槽底部产生硼化钛。利用这些砂轮进行了磨削实验。结果表明，该烧结层可用于淬硬模具钢的磨削。激光束扫描间隔小的砂轮能较好地去除工件，磨损小。
This paper deals with development of a titanium boride grinding wheel. At first, a desired shape is made of titanium. Next, boron powder is spread on a surface of the titanium. The surface is scanned by a laser beam, and then titanium boride is produced on the surface of the titanium by the chemical reaction between the boron powder and the titanium. The produced titanium boride is used as a grinding wheel. Titanium substrates of plate shape are used in this paper for the experiments of producing titanium boride. The surface layers of the substrates are examined by an X-ray diffraction and titanium boride is detected in the layers. The cross sections of the layers are examined by an EPMA and EDS. Titanium boride is produced at the bottom of the groove those are generated by the laser scanning. Grinding experiments are performed using these grinding wheels. The results show that the sintered layer can be used for grinding of hardened die steel. The grinding wheel with small scanning interval of a laser beam can remove work material better and has small wear.
