The research progress of rapid electroless nickel plating in environmental conditions at low temperature was reviewed in this paper.The basic principles and the methods of constructing active catalytic plating were presented,and some advices on how to improve the deposition rate of electroless Ni-P plating at low temperature to obtain environmental electroless bath were put forward. The difficulty of electroless nickel plating on substrates could be solved through the combination of acidic and alkaline methods,and surface catalytic electroless nickel plating was an important accelerating technique. Moreover,the research on the reaction mechanism of fast catalytic nickel plating at low temperature would provide theoretical foundation for development of electroless Ni-P alloy catalytic solution with energy saving,environmentally friendly and high efficiency,and pulse electroless nickel plating played an active role in enhancement of the production efficiency. Furthermore,new technology of plating bath regeneration should be developed to make plating bath working in long-term operation with reduced waste liquid discharge.
