Effect of electrical parameters on characteristics of microarc oxidation coatings of commercially pure titanium in colloid
电学参数对胶体中工业纯钛微弧氧化膜特性的影响

The effects of the pulse voltage amplitude (U) and duty cycle (d) on the growth characteristics, microstructure, phase component and corrosion resistance of the coating formed by microarc oxidation (MAO) on commercially pure titanium substrates in colloid have been systematically studied. The results show that, with the increase of U or d , the coating thickness increases almost linearly, the poresize and the roughness of the surface increases gradually, while the pore density decreases. The coatings almost...
