The surface functionality of interacting components is determined by evaluating geometric surface structure. Hence, the ceramic femoral heads originated from precision machining were subject to measurement and analysis with regard to roughness, surface damages and deviation from roundness. A variety of measurement techniques were applied in order to thoroughly examine the product quality. The obtained results proved in accordance with the specification: Ra was not greater than 0.05 µm, whereas Δ was less than 10 µm (5 µm) when ceramic balls were used in conjunction with a polyethylene (ceramic) socket. Additionally, the surface damages which can affect the life of a friction pair were analyzed.
相互作用部件的表面功能通过评估几何表面结构来确定。因此,对源自精密加工的陶瓷股骨头进行了粗糙度、表面损伤和圆度偏差方面的测量与分析。为了全面检查产品质量,应用了多种测量技术。所得结果符合规格要求:当陶瓷球与聚乙烯(陶瓷)承窝配合使用时,表面粗糙度Ra不大于0.05 µm,而圆度偏差Δ小于10 µm(5 µm)。此外,还分析了可能影响摩擦副寿命的表面损伤情况。
