In the present paper, sliding wear characteristics of seven weight% yttria stabilized zirconia (7YSZ) sol-gel deposited on to air plasma sprayed CoNiCrAlY bond-coated Inconel 800 superalloy has been studied. For this, sliding wear tests have performed on pin-on-disc friction and wear test rig by varying experimental parameters applied load, sliding velocity, disc speed and temperature as per L16 orthogonal arrays of Taguchi. Taguchi method has been used to perform experiments to know the effect of interaction of variables on dry sliding wear behavior. The optimal experimental parameters have been obtained by orthogonal arrays, signal-to-noise ratio (SNR) and analysis of variance (ANOVA) for uncoated and coated Inconel 800 superalloy substrate. Results have shown temperature as the most influencing parameter for uncoated samples and coated samples, both. However, compared with coated samples, applied load has been found significant factor for uncoated samples. It has been exhibited better wear resistance in the sol-gel derived YSZ coated surface of IN800 superallloy substrate.

未涂覆的IN800超级合金和溶胶-凝胶基浸涂IN800基底的干滑磨损（DSW）研究

本文研究了在空气等离子喷涂CoNiCrAlY粘结涂层Inconel 800高温合金上沉积的7重量％氧化钇稳定的氧化锆（7YSZ）溶胶-凝胶的滑动磨损特性。为此，根据Taguchi的L16正交阵列，通过改变施加载荷，滑动速度，圆盘速度和温度的实验参数，对销盘摩擦和磨损试验台进行了滑动磨损测试。Taguchi方法已用于进行实验，以了解变量相互作用对干滑磨损行为的影响。通过正交阵列，信噪比（SNR）和方差分析（ANOVA）获得了未涂覆和涂覆的Inconel 800高温合金基材的最佳实验参数。结果表明，温度是未镀膜样品和镀膜样品影响最大的参数，都。但是，与涂层样品相比，已发现施加载荷是未涂层样品的重要因素。在IN800超合金基体的溶胶-凝胶衍生的YSZ涂层表面上已显示出更好的耐磨性。
