  2. When subjected to such process, the steel surface will be covered with numerous fine manganese - phosphate crystals so that the crystal nucleus necessary for manganese - based phosphorizing increases greatly in number. this may not only accelerate phosphorization and properly lower the temperature of phosphorization, but also prevent big - size crystals from being generated. as a result, the resulting phosphate has improved fineness and evenness

    鋼鐵經它處理后,會在其表面覆蓋上許多極細小的錳磷酸鹽結晶,使錳系磷化所需晶核數目大為增加,以而加速磷化反應速度,並能適當降低磷化溫度,還可以阻止粗大結晶的生成,因此形成的磷化膜更加均勻細致。
