of hopeite. The Zn-Ca-Ce-P coating has the potential for the primer coating on magnesium alloys. Key words: AZ31 magnesium alloy; cerium; zinc calcium phosphate; chemical conversion coating; corrosion...-Ca-Ce-P coated alloy is significantly delayed relative to that of the Zn-Ca-P coated alloy. This consequence implies that the chemical conversion coating can hardly protect the substrate from......

mechanism of conversion coating forming process of B95 aluminium alloy in cerium(Ⅲ) salt solution GU Bao-shan, YANG Pei-yan (National Engineering Laboratory for Advanced Coatings Technology of Metal Materials, China Iron and Steel Research Institute Group, Beijing 100081, China) Abstract: The electrochemical impedance spectroscope (EIS) was used to study the conversion coating forming process of B95......
was characterized by X-ray photoelectron spectroscopy (XPS). The corrosion behaviors of 2195Al-Li alloy and conversion coating were assessed by means of potentiodynamic polarization curves. The experimental results indicated that after post-treatment the surface quality was improved signifi-cantly. According to XPS, the conversion coating after post-treatment was mainly composed of CeO2, Ce2O3......
