夹钎镀是将电刷镀与钎焊技术结合起来的一项修复技术,对于划痕、擦伤和凹坑的修补效果很好。例如,液压设备中的柱塞、缸体等是最重要的基础件,由于润滑油中混入杂质或工件表面的灰砂等硬颗粒造成表面拉伤、划伤或被化学介质腐蚀生成凹坑,从而导致液压油泄漏,影响机械设备的正常使用。采用夹钎镀技术,即对缺陷部位进行电净、活化处理后镀铜或锡镀层,改善基体表面的钎焊性,然后用钎焊锡或合金将缺陷填补满,铲刮钎焊层至低于工件基准表面0.05mm左右,然后在钎焊层上 Clamp brazing is a repair technique that combines brush plating with brazing technology and works well for scratches, scratches and pits. For example, the plunger and cylinder in the hydraulic equipment are the most important basic parts. The surface is scratched due to the hard particles such as lime sand mixed with impurities or the surface of the workpiece, scratched or etched by the chemical medium to form pits, Resulting in leakage of hydraulic oil, affecting the normal use of machinery and equipment. The use of brazing brazing technology, that is, the defect site for the net, after activation of copper or tin plating to improve the brazing of the substrate surface, and then use brazing solder or alloy to fill defects, scraping the brazing layer to low The workpiece reference surface of about 0.05mm, and then in the brazing layer
