Technology for Fast Electroless Ni-P Alloy Plating on Beryllium and Properties of the Coating

With a view to the nature of beryllium(Be),fast electroless Ni-P alloy plating was chosen to conduct the surface modification of Be.Thus the influences of the concentration of reducing agent and complexing agents and the pH value and temperature of the plating bath on the plating rate and properties of the (Ni-P) alloy coating were investigated.The wear resistance,corrosion resistance,and adhesion to substrate of the Ni-P alloy coating were examined.It was found that the plating bath had good stability and fast plating rate.It was feasible to prepare compact and uniform Ni-P alloy coating of good adhesion strength and corrosion resistance by properly controlling the plating parameters.
