Effects of Different Pulses on Film Formation on Micro-arc Oxidation Magnesium Alloy
Micro-arc oxidation experiments were carried out for AZ91D magnesium alloy by unipolar
ambipolar pulse and discharge circuit to remove output modes to investigate wave types of load voltage and current under different pulse types for micro-arc oxidation and effects on MAO process and efficiency for AZ91D alloy. The results reveal that capacitive load characteristics can be cancelled by using discharge circuit pulse mode
which makes the MAO process stable and arc point uniform
surface of film smooth and gas hole heterogeneous and compact
