摘要
分别使用Ni–Cr和Cu–Sn–Ti等2种合金钎料真空钎焊制作镀钛和无镀层金刚石钻头,通过钻进玻化砖试验,研究了4类钻头的钻进性能。试验结果表明:Ni–Cr钎料钎焊制作的镀钛金刚石钻头与无镀层金刚石钻头比较,钻头平均寿命下降了41.7%;Cu–Sn–Ti钎料钎焊制作的镀钛与无镀层金刚石钻头比较,钻头平均寿命相当,但镀钛金刚石钻头的钻孔效率更高,并对其机理进行了分析。
Using Ni-Cr and Cu-Sn-Ti solders to produce the brazed Ti-coated and uncoated diamond drills, performances of four types of diamond drill bits were investigated through the drilling test of vitrified brick. The results show that the average life of Ti-coated diamond drill using Ni-Cr solder brazing decreased by 41.7 compared with the uncoated diamond drilll. The average life of Ti-coated diamond drill and uncoated diamond drill using Cu-Sn-Ti solder brazing are basically the same, but the drilling efficiency of Ti-coated diamond drill is significantly higher. Finally, the mechanism of the above conclusion is analyzed.
