为了获得高强度的铜钎焊接头,必须从被铜钎焊的铸铁表面消除片状石墨。本文研究了消除石墨的方法对灰铸铁钢钎焊接头的金相组织和剪切强度的影响。
In order to obtain high-strength copper brazed joints, flake graphite must be eliminated from the surface of cast iron brazed with copper. In this paper, the effects of graphite removal methods on microstructure and shear strength of gray cast iron brazed joints were studied.
