MAO coatings have intensively attracted the attention of many research groups due to its desirable characteristics, especially the coatings on the substrates of titanium and its alloys. Recently years, the performances in all fields and application on the coatings fabricated by MAO have been developing and studying by many units in the world. Because MAO is a complicated process, which is controlled by multifactor, different technical parameters, as-deposited MAO coatings show various properties...
