Fe粉表面化学镀Ni-P的热力学与动力学
Thermodynamics and kinetics of electroless Ni-P plating on Fe powder
摘要
Abstract
In order to improve the properties of Fe powder such as inoxidability and abrasion resistance, and drop the sintering temperature, the electroless Ni-P plating on Fe powder was prepared successfully. Bockris equation of the electrochemistry was applied to the thermodynamics of Fe powder electroless Ni-P plating for controlling its deposit rate and deposit mechanism. The thermodynamics functions △Gdep(o), △Sdep(o) and △Hdep(o) were figured out by studying the deposit amount of coating. In addition, the experiential equation of electroless deposition was established. The results show that the optimal temperature of electroless plating is 362 K. If it is higher than such temperature, the plating liquor may easily decompose. Within the range of optimal temperature, the chemical reaction can occur spontaneously. The reaction of this system is endothermic.关键词
