本文介绍了采用通用的射频溅射设备,对金刚石晶粒表面进行金属镀膜的试验研究,使原来不具有焊接性能的金刚石获得了可焊性。通过试验解决了向金刚石晶粒表面镀制金属膜层的连续性和均匀性问题。曾用过钨、钽、钛、钼、镍、铬、钴、铜等金属作为镀层金属,作过单层和复层镀膜、镀膜后的金刚石与45号中碳钢钎焊以及钎焊剪切强度测定等工作。 This article describes the use of common RF sputtering equipment, the diamond grain surface of the metal coating experimental study, so that did not have the original welding performance of the diamond obtained solderability. The problem of continuity and uniformity of the metal film plated on the surface of the diamond grains is solved through experiments. Have used tungsten, tantalum, titanium, molybdenum, nickel, chromium, cobalt, copper and other metals as a coating of metal, as a single and double coating, after coating the diamond and 45 of medium carbon steel brazing and brazing shear Strength determination and other work.
