摘      要：Chromium-plating is considered an effective method to improve surface properties of metal *** sputtering was applied to prepare Cr coating on AZ31 magnesium alloy and the influence of bias voltage on properties of Cr coating was *** obtained coatings present an(110) preferred texture and have a developed columnar *** increasing bias voltage,the surface structure of Cr coating becomes *** of the Cr-coated AZ31 have much higher surface microhardness than bare *** Cr coating deposited on AZ31 at bias voltage of -150 V has a higher corrosion potential than *** result of the immersion test shows that it decreases the damaged area compared with bare *** failure of the coated AZ31 is mainly attributed to the existence of through-thickness defects in the coating.
