Abstract:
      Abstract: Cr-TiAlSiN composite coatings were deposited on the substrate of zirconium alloys tubes by multi-arc ion plating and intermediate frequency unbalanced magnetron sputtering, respectively. The micro-morphology of surface and cross-section of the composite coatings was observed by a scanning electron microscopy; the porosity and the quantity of large particles on the surface were analyzed by Image J software; the adhesion strength between the coatings and substrate was measured by a?pull pressed?spring?testing machine; the samples were subjected to high temperature oxidation test at 800℃ and high temperature quenching test at 1200℃ by using a high temperature furnace. The results show that there are more large particles on the surface of the coatings deposited by multi-arc ion plating, but the porosity of that is relatively low, so that the high temperature oxidation resistance behavior is better. The interface of the composite coatings is relatively clear and uniform, and the adhesion strength between the coatings and substrate is relatively strong, both of which are higher than 22.68MPa. According to the high temperature quenching test at 1200℃, it also turns out from the side that the adhesion strength is better with the process of multi-arc ion plating.
