The Influences of Anticipated Heat Treatment on the Electroless Nickel Plating on Magnesium Alloys

Abstract:

In this paper, effects of anticipated heat treatment on the electroless nickel plating coated on magnesium alloys AZ91D were investigated by using heat treatments of solution (T4) and solution + aging (T6) before electroless nickel plating. The influence of anticipated heat treatment on the structure, composition and anti-corrosion property of electroless coating were studied by using Scanning Electrical Microscope (SEM), EDS and Corrodkote corrosion test. It is shown that compared with the as-casted magnesium alloys and samples treated with T4, the deposition rate of Ni, the P contained in the coating and the anti-corrosion property of samples treated with T6 are the highest for the given system studied, and T6 treatment can promote the anti-corrosion property of the coating effectively.
