摘要: 利用化学复合镀的方法,通过外加磁场这一新工艺的引入来制备NiPPTFE复合镀层。研究过程中,在其它工艺条件不变的情况下,通过入镀时间、磁场强度、磁场方向等因素的改变,探究磁场对复合镀工艺及镀层性能的影响。研究结果表明:当有外加磁场作用时,复合镀层中的粒子沉积速度和粒子含量显著提升,同时,外加磁场强度的改变对所得复合镀层的厚度、耐蚀性能、成分都有较大影响。

Abstract: By introducing a new process of external magnetic field, NiPPTFE composite coatings were prepared using electroless composite plating. At the same conditions of other processes, we explored the influence of magnetic on composite plating process and coatings performance by changing some factors such as plating time, magnetic field strength, magnetic field direction. The results showed that external magnetic field improved deposition rate and PTFE particles content of composite coatings, meanwhile, some performances of composite coating like thickness, corrosion resistance, ingredient were effected by external magnetic field strength.
