Local arc discharge mechanism and requirements of power supply in micro-arc oxidation of magnesium alloy

Ming CHEN, Yuezhou MA, Yuan HAO,

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 1,   Pages 98-105 doi: 10.1007/s11465-009-0088-8

Abstract: To study the requirements of the power supply in micro-arc oxidation (MAO) of magnesium alloy, many experimentswere performed under the DC, unipolar, and ambipolar pulse output modes.The purpose of pulse supply is to inhibit the large-arc discharge by intervening proper cooling time,but can be reached by an ambipolar pulse supply because the negative pulse period acts as cooling timeUsing a discharge loop to remove the influence of load capacitive, a new type of pulse power supply for
