The feasibility of electroless Ni-plating was explored in order to solve the problem of the restoration of the parts of aircraft made of high strenth steel. The flow and criterion of the restoration technology were were preliminarily investigated. We have measured the hardness, adhesion strength and antiwear performance of the coating. The results show that the electroless Ni-plating process for restoring the scuffed surface of aircraft parts made of high strenth steel has the advantages of simple procedure, easy operationg, and low cost. The coating is well adhered to the substrate and meets with the requirement for performance. In one word, the restoration technology of aircraft parts made of high strenth steel is good for extending.
