AZ91D is an excellent light weight and high strength material,it has the advantages of low density，high specific strength, good heat dispersion, mechanical properties and electromagnetic shielding etc, however, the poor corrosion resistance seriously limits its wide application. electroless Ni plating is one of the most common and economical surface treatments for AZ91D ,because electroless nickel plating can form a uniform thickness coating, it has good corrosion and wear resistance.

THE PERFORMANCE FEATURE:

The uniformity of electroless Ni plating is excellent, The layer thickness could be made according to customer requirements

It can pass 96 hours salt spray test

The coating and the substrate are not separated when workpiece bend 360 °

Baking 30 min in 200℃(No bubble)

The rate of yield  could get above 95%
