The present sol-gel processes present a surface modification technique for improving the sliding wear resistance characteristics of metallic materials of 2024-T351 aluminum alloy. With the help of dip-coating methods, seven weight% yttria stabilized zirconia (7YSZ) as a top-coat is applied over the air plasma sprayed bond-coated materials, CoNiCrAlY, on aluminum alloys. Thereafter, coating thickness is measured using an optical microscope. Further, sliding wear tests are performed on Pin-On-Disc Friction and Wear test rig as per L₁₆ orthogonal arrays of Taguchi method. Investigations revealed temperature as the most influencing parameter for uncoated samples while temperature and applied load, both for coated samples. In comparison to base metallic alloys, sol-gel derived YSZ coating on the AA2024 surface exhibited better wear resistance, resulted into the reduction of wear rate.

本溶胶-凝胶法提出了一种表面改性技术，用于改善2024-T351铝合金金属材料的耐滑动磨损特性。借助浸涂法，将7％重量百分比的氧化钇稳定的氧化锆（7YSZ）作为面漆涂覆在铝合金上的空气等离子喷涂粘结涂层材料CoNiCrAlY上。此后，使用光学显微镜测量涂层厚度。此外，根据L ₁₆在圆盘销摩擦和磨损试验台上进行滑动磨损试验Taguchi方法的正交数组。调查显示，对于涂层样品，温度是未涂层样品影响最大的参数，而温度和施加的载荷对样品来说都是最重要的参数。与贱金属合金相比，AA2024表面的溶胶-凝胶衍生YSZ涂层具有更好的耐磨性，导致磨损率降低。
