作者在《应用刷镀修复机床铸铁导轨工艺研究》一文中,就电刷镀修复机床铸铁导轨的工艺方法和工艺特点进行了简要的分析,并且在文中提到对于窄而深的划伤沟槽可采用“夹钎镀”,即先在沟槽底部镀上薄薄的一层镍和一层铜,然后在铜层上纤焊锡铋合金,最后在锡铋合金上刷镀铜和镍。这样既可保证填补的划伤有一定的强度,又保证 In a paper entitled “Application of Brush Plating to Repair Cast Iron Rail Technology,” a brief analysis is made on the technological process and process characteristics of the brush plating for repairing the cast iron rail of a machine tool. The article also mentions that for narrow and deep scratched grooves Can be used “brazing brazing”, that is, first in the bottom of the trench plated with a thin layer of nickel and a layer of copper, and then the fiber in the copper layer bismuth alloy, and finally brush the tin-bismuth alloy copper and nickel. This will ensure that there is a certain degree of scratch to fill, but also to ensure that
