本文论述了低温镀铁时,铁离子在电场力作用下,大量拥向阴极,离子沉积速度很快,来不及进行规则排列构成长程序,于是形成微晶结构和参杂一定的非晶态结构,微晶结构的晶界强化,微观应力所引起的应力强化,微晶亚稳相晶格畸变所引起的加工硬化,以及非晶亚稳相所造成的非晶态强化,导至了镀层的高强度、高硬度及良好的耐磨性。
This article discusses the low-temperature iron plating, the iron ions under the action of the electric field, a large number of cathodes toward the cathode, the ion deposition rate is too fast, too long to arrange a long sequence of rules, so the formation of microcrystalline structure and mixed with some amorphous structure, The grain boundary strengthening of the microcrystalline structure, the stress strengthening caused by the micro stress, the work hardening caused by the metastable lattice of the crystalline metastable phase, and the amorphous strengthening caused by the amorphous metastable phase lead to the high plating Strength, high hardness and good wear resistance.
