采用多弧离子镀技术在锆合金表面制备了纯Cr涂层。利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)和划痕仪分析了弧电流对纯Cr涂层表面形貌、物相结构以及膜基结合力的影响,并采用Image J图像处理软件对纯Cr涂层表面大颗粒分布进行统计和分析。结果表明,随着弧电流的增大,纯Cr涂层表面大颗粒尺寸先增大后减小,单位面积内大颗粒数目则先减少后增多,同时纯Cr涂层的择优生长趋势由(110)晶面变为(200)晶面,且纯 Cr涂层与锆合金基材的膜基结合力先减小后增大。

The pure Cr coatings were deposited on the surface of zirconium alloy by multi-arc ion plating technology. The effects of arc current on surface morphology, phase composition and interracial adhesion were analyzed by scanning electron microscopy （SEM） ,X-ray diffractometer （XRD） and scratch tester. Image J image processing software was used for statistics and analysis of the distribution of the micro particles in the surface of pure Cr coatings. The results show that with the increase of arc current, the size of microparticles in pure Cr co...
