采用多弧离子镀技术在不同的占空比条件下于锆合金表面制备TiAlN涂层.利用扫描电子显微镜观察涂层的表面和截面微观形貌;利用能谱分析涂层的表面元素成分;利用箱式电阻炉测试涂层在800 ℃空气中持续进行3 h的高温氧化性能;利用自动划痕仪在常温下测试涂层的膜基结合力;利用X射线衍射仪分析涂层的物相组成.结果表明:占空比可显著影响TiAlN涂层的表面和截面的微观形貌、元素成分比例、高温抗氧化性、膜基结合力及物相组成.随占空比增大,TiAlN涂层表面的大颗粒数目减少,表面质量得到改善,涂层的沉积速率先增大后减少,致密性一直增加;能谱分析表明Al元素与Ti元素质量比逐渐减小,Al元素与Ti元素的质量...

TiAlN coatings were deposited on the surface of zirconium alloys by multi-arc ion plating with different duty ratio. The surface and cross-sectional micro-morphologies were observed by scanning electron microscopy (SEM), the elemental composition of the coatings was analyzed by an energy dispersive spectroscopy (EDS). The high temperature oxidation resistance performance of coatings was tested by a box-type resistance furnace in air at 800 ℃ for 3 h. The adhesion strength of the coating to the substrate was tested by an automatic scratch teste...
