外加磁场下AZ31镁合金磷化膜结构及耐蚀性研究
Study on the Structure and Corrosion Resistance of Phosphoric Conversion Coatings on AZ31 Magnesium by Applying Magnetic Field
摘要
Abstract
In order to obtain excellent phosphate conversion coatings on the surface of AZ31 magnesium alloy, a novel phosphate process for magnesium alloy by applying magnetic field was developed. The surface morphology, structure and corrosion resistance of conversion coating were studied by SEM, AFM, XRD and Electrochemistry workstation. The results show conversion coatings of AZ31 magnesium alloy can be further formed when the direction of magnetic field is vertical to the surface of magnesium alloy. Conversion coatings are mainly made up of crystal Zn3(PO4)2 ? 4H2O and AlPO4 and non-crystal Mn compounds. We can obtain the dense conversion coatings by applying magnetic fields in the phosphate process.关键词
