When compared with pvd , cvd , fad film is dense , flat and lubricous because of 100 ionization rate of sediment after magnetic filtering without any large granule . moreover , it has good corrosion resistance and is not easy to be removed 与pvd cvd技术比较,由于磁过滤后沉积粒子的离化率为100 ,并且没有大颗粒, fad形成的薄膜非常致密和平整光滑,抗腐蚀性能好,且与机体的结合良好不易脱落。
