纺织检测设备铝合金表面化学镀镍的质量控制

Quality control of the electroless nickel plating on the surface of aluminum alloy for textile testing equipment

纺织检测设备大量使用铝合金材料,材料表面处理工艺的优劣直接影响检测设备的精度和使用寿命。纺织检测设备铝合金表面化学镀镍前处理工艺、镀液中各化学组分和工艺条件都会对镀层质量产生影响,其中最主要的影响因素是主盐、络合剂、缓冲剂、温度和pH值,研究确定了适合的化学镀镍配方及工艺。

The aluminum alloy material is widely used in textile testing equipment. The precision of the measuring equipment and service life are depended on the advantages and disadvantages of the material surface processing technology. The plating quality is affected by the pretreatment process, chemical composition in the plating solution and process conditions of the textile testing equipment of aluminum alloy surface chemical nickel plating. The main salt and complexing agent, buffer, temperature and pH value are main influence factors. The suitable chemical plating nickel formula and process are determined.
