Paper Title:
Study on Micro-Arc Oxidation Composite Ceramic Coating Properties in the Textile Machinery Spare Parts
  Abstract

This article uses independently develops micro-oxidation installment, systematically studied and optimized the silicate system solution,the silicate and the different recombiner composition compound system solution that are used in SJDM-1 rare earth magnesium alloys micro-oxidation and different electrical parameters that affect corrosion resistance of ceramic coating through the condition experiment and the orthogonal experiment.Using scanning electron microscopy (SEM) , X-ray diffraction (XRD) , coat thickness tester and drip experiment, the surface morphology of ceramic layer of SJDM-1 rare earth magnesium alloys are observed,and composition, thickness and corrosion resistance of SJDM-1 rare earth magnesium alloys in different solution are tested. Meanwhile combining the micro-oxidation solution and electrical parameters that are optimized, the difference of corrosion resistance between the hydration seals hole and solvent seals hole are compared after micro-oxidation. In addition, corrosion resistance of MAO ceramic layers between the two different materials RE magnesium alloys (casting SJDM-1, deformation SJDM-2)under the same conditions. Finally, micro-oxidation solution failure and the process of the ceramic layer corrosion are analysed. Mechanism of the discharge breakdown that influence the corrosion resistance of the micro-oxidation ceramic coating is explored, come to the internal and external factors that affect corrosion resistance of the micro-oxidation ceramic layer.
