为了对比研究磁控溅射和多弧离子镀两种工艺制备的Cr涂层Zr-4合金微观结构和抗高温氧化性能,分别采用直流磁控溅射和多弧离子镀制备了Cr涂层Zr-4合金样品,在空气气氛中开展高温氧化试验研究。结果表明,磁控溅射制备的Cr涂层Zr-4合金样品表面光滑,Cr涂层沿着(211)晶面择优生长,而多弧离子镀制备的Cr涂层Zr-4合金样品表面存在大量的滴液,Cr涂层沿着(110)晶面择优生长。高温氧化试验结果显示,磁控溅射制备的Cr涂层Zr-4合金样品的氧化质量增加约为多弧离子镀的一半,氧化后的微观结构显示磁控溅射制备的样品还有约4 μm厚的残留Cr涂层,且O原子仅仅大量扩散到距表面约8 μm处,而多弧离子镀制备的样品表...

In order to compare the microstructure and high temperature oxidation resistance of Cr-coated Zr-4 alloy prepared by magnetron sputtering and multi-arc ion plating,Cr-coated Zr-4 alloy were prepared by DC magnetron sputtering and multi-arc ion plating,respectively.And the high temperature oxidation resistance was studied in air atmosphere.The results show that the Cr-coated Zr-4 alloy specimen prepared by magnetron sputtering has smooth surface,and the Cr coating grows preferentially along the(211)crystal plane,while there are a lot of droplets...
