In this study, the effect of counterbody on the dry sliding wear behavior of plasma sprayed calcia-stabilized zirconia coating was investigated. The commercial ZrO₂-5CaO coating powder (Metco 201NS, −53 + 11 μm) was deposited onto the surface of AISI 316L substrate using Atmospheric Plasma Spray method. Dry sliding wear tests were performed with Al₂O₃ and WC-Co counterbody balls at different loads (5 N, 10 N and 15 N) and sliding speeds (10 mm/s, 20 mm/s and 30 mm/s) using a ball-on-disc device. From the test results, the COF values obtained from the Al₂O₃ ball were recorded to be lower than that of the WC-Co ball especially at 20 N and 30 N loads. The sliding speed did not cause a remarkable change in the COF values of the wear tests performed with both counterbody balls. However, in the case of WC-Co ball, COF values also increased especially with increasing the load from 5 N to 10 N at the 20 mm/s of sliding speed. In general, increasing load and sliding speed led to an increase in the wear volume loss values for all the tests. When using Al₂O₃ ball, under the 5 N load, lots of pitting and spalling zones were observed, whereas for 10 N and 15 N loads, plastically deformed worn areas which had lots of wear debris and deep cracks were determined. As for the WC-Co ball, the plastic deformation was observed as the predominant wear mechanism as well as the swelling-induced spallation and delamination. In addition, the wear mechanisms identified as a result of this study were explained by associating them with the Hertzian contact theory.

在这项研究中，研究了配体对等离子喷涂氧化钙稳定的氧化锆涂层的干滑磨损行为的影响。使用大气等离子喷涂法将商业化的ZrO ₂ -5CaO涂层粉末（Metco 201NS，-53 + 11μm）沉积到AISI 316L基板的表面上。使用不同负载（5 N，10 N和15 N）和滑动速度（10 mm / s，20 mm / s和30 mm / s）的Al ₂ O ₃和WC-Co配体球进行干式滑动磨损测试圆盘设备。根据测试结果，从Al ₂ O ₃获得的COF值据记录，该球低于WC-Co球，尤其是在20 N和30 N的载荷下。滑动速度并未对两个副球进行的磨损测试的COF值产生显着变化。但是，在WC-Co球的情况下，COF值也会增加，尤其是在以20 mm / s的滑动速度将载荷从5 N增加到10 N的情况下。通常，增加载荷和滑动速度会导致所有测试的磨损量损失值增加。使用Al ₂ O _3时球在5 N载荷下观察到大量的点蚀和剥落区域，而对于10 N和15 N载荷，则确定了塑性变形的磨损区域，该区域具有大量的磨损碎片和深裂缝。对于WC-Co球，观察到塑性变形是主要的磨损机理，也是膨胀引起的散裂和分层。另外，通过与赫兹接触理论联系起来解释了这项研究确定的磨损机理。
