High corrosion resistance of electroless composite plating coatings on AZ91D magnesium alloys
The process of electroless plating Ni–P on AZ91D magnesium alloys was improved. The Ni–P–ZrO 2 composite coatings and multilayer coatings were investigated based on the new electroless plating process. The coatings surface and cross-section morphologies were observed with scanning electron microscop...

| description | The process of electroless plating Ni–P on AZ91D magnesium alloys was improved. The Ni–P–ZrO
2 composite coatings and multilayer coatings were investigated based on the new electroless plating process. The coatings surface and cross-section morphologies were observed with scanning electron microscopy (SEM). The chemical compositions were analyzed by EDXS. The corrosion behaviors were evaluated by immersion, salt spray and electrochemical tests. The experimental results indicated that the Ni–P–ZrO
2 composite coatings suffered attack in NaCl solution but displayed passivation characteristics in NaOH and Na
2SO
4 solutions. The corrosion resistance of Ni–P–ZrO
2 coatings was superior to Ni–P coatings due to the effect of ZrO
2 nano-particle. The multilayer coatings consisting of Ni–P–ZrO
2/electroplating nickel/Ni–P (from substrate to surface) can protect magnesium alloys from corroding more than 1000
h for the salt spray test. |
