块状非晶态镍磷合金的电化学沉积制备与结构研究

采用电化学沉积方法,在不同的工艺条件下,制备块状非晶态Ni-P合金,并研究了工艺条件和磷含量对块状Ni-P合金结构的影响.结果表明,电化学沉积制备块状非晶态Ni-P合金的方法是可行的,较低的pH值、较高的温度和较低的阴极电流密度更有利于非晶态结构的形成.试验中还发现,磷含量是决定块状Ni-P合金结构的主要因素,随着磷含量的增加,块状Ni-P合金由晶态向非晶态结构转变.

Preparation of bulk amorphous Ni-P alloy by electrochemical deposition and its structure research

Bulk amorphous Ni -P alloys were prepared at various technology conditions by electrochemical deposition, and the effects of technology conditions and phosphorus contents on the bulk Ni - P alloy structures were also studied. The results showed preparation of bulk amorphous Ni - P alloy by electrochemical deposition was validated. It was indicated that lower pH value, higher temperature, and lower cathodic current density could promote the formation of the amorphous structure. The bulk Ni - P alloy structures were also found to be very phosphorus content dependent, and bulk Ni - P alloys transformed from the crystal to the amorphous structure with an increase in phosphorus content.
