Table tennis racquet blades (TTRBs) are specialized wood materials known for their excellent mechanical properties. As one of the widely used physical vapor deposition technologies, magnetron sputtering has become the most effective method for preparing various thin film materials. In this study, the surface of the TTRB is coated with a Ti film with different thicknesses by magnetron sputtering to improve the performance of the TTRB. The surface roughness, crystal structure, viscoelasticity of the TTRB were analyzed by means of non-contact surface profilometry, X-ray diffraction (XRD), and dynamic mechanical analysis (DMA). In order to effectively test TTRB properties, three types of testing devices were designed, including free-fall rebound, laser vibration measurement, and the dynamic rebound test. The results reveal that the deposition of a Ti film on the surface of the TTRB improves the rigidity and rebound efficiency of the TTRB. Under optimized conditions, the initial amplitude, vertical rebound distance, and rebound rate can reach 2.1 μm, 23.7 cm, 13.7%, respectively, when the deposition thickness is 5 μm. It is anticipated that the modification and the corresponding detection methods developed in this study can foster innovative product development, standardize the TTRB industry, and contribute to the advancement of table tennis.
乒乓球拍底板（TTRBs）是具有优异机械性能的特殊木材材料。作为广泛应用的物理气相沉积技术之一，磁控溅射已成为制备各种薄膜材料最有效的方法。在本研究中，通过磁控溅射在TTRB表面涂覆不同厚度的Ti膜，以提高TTRB的性能。借助非接触式表面轮廓仪、X射线衍射（XRD）和动态力学分析（DMA）对TTRB的表面粗糙度、晶体结构、粘弹性进行了分析。为了有效测试TTRB性能，设计了三种测试装置，包括自由落体回弹、激光振动测量和动态回弹测试。结果表明，在TTRB表面沉积Ti膜提高了TTRB的刚性和回弹效率。在优化条件下，当沉积厚度为5μm时，初始振幅、垂直回弹距离和回弹率分别可达2.1μm、23.7cm、13.7%。预计本研究中开发的改性方法及相应检测方法能够促进创新产品开发，规范TTRB行业，并推动乒乓球运动的发展。
