摘要
提出一种制作CVD金刚石厚膜焊接刀具的新工艺。采用电子辅助化学气相沉积法 (EACVD)制备直径10 0mm、厚度 0 8～ 1mm的金刚石厚膜 ;通过对金刚石刀头表面进行金属化处理 (化学气相沉积W膜 ) ,改善了金刚石的耐高温性及与低熔点合金焊料的浸润性 ,可在大气环境下实现金刚石刀头与刀架的焊接。车削试验结果表明
A new technology for manufacturing CVD diamond thick film cutters is presented. Diamond films with 0 8～1mm thickness and 100mm in diameter are prepared by electron assistant chemical vapor deposition (EACVD) method. Through metallization process with a W layer deposited on the diamond surface by CVD technology, their ability to be moistened by low melting point alloy solders and endure high temperature can be considerably improved, and the treated CVD diamond thick film chips can be welded to holders at atmosphere. The result of a turning test shows that the diamond turning cutter manufactured by the new technology is suitable for the precise processing.
