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。
