钎焊镀钛金刚石钻头的研制及其钻进性能分析
Development and drilling performance of the brazed Ti-coated diamond drill bits
摘要
Abstract
Using Ni-Cr and Cu-Sn-Ti solders to produce the brazed Ti-coated and uncoated diamond drills,the 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.关键词
