钛合金叶片在实际工况中通常承受不同程度的微动磨损，为了提高钛合金叶片的耐磨性需要在其表面制备抗磨、抗冲击的耐磨层，研究耐磨层的微动磨损性能对叶片的工作可靠性和服役寿命具有重要作用。采用钛基钎料及感应钎焊工艺，在TC4钛合金基体上制备WC耐磨层，研究载荷、位移和频率等工况参数对耐磨层微动磨损性能的影响。结果表明：在小载荷条件下，位移和频率的变化对耐磨层平均摩擦系数影响不大；在中、高载荷条件下，频率变化对耐磨层平均摩擦系数影响较小，位移变化对耐磨层平均摩擦系数影响较大。在小位移条件下，耐磨层平均摩擦系数随载荷的增大而减小；在中、大位移条件下，载荷的变化对耐磨层平均摩擦系数的影响较小。位移幅值的变化对耐磨层的磨损体积具有显著影响。耐磨层的磨损形式主要为磨粒磨损和黏着磨损。
Titanium alloy blades usually bear different degrees of fretting wear in actual working conditions. In order to improve the wear resistance of titanium alloy blades, it is necessary to prepare wear-resistant and impact resistant wear-resistant layers on them. Studying the fretting wear performance of wear-resistant layers plays an important role in the working reliability and service life of blades. WC wear-resistant layer was brazed on TC4 substrate by induction brazing using titanium based brazing filler metal. The effects of different loads, displacements and frequency vibrations on fretting wear properties of wear-resistant layer were studied. The results show that under the condition of small load, the change of displacement and frequency has little effect on the average friction coefficient of the wear-resistant layer; under the condition of medium and high load, the change of frequency has little influence on the average friction coefficient of the wear-resistant layer while the change of displacement has a great influence on it. Under the condition of small displacement, the average friction coefficient of wear-resistant layer decreases with the increase of load, while under the condition of medium and large displacement, the change of load has little effect on the average friction coefficient of wear-resistant layer. The change of displacement amplitude has a significant influence on the wear volume of the wear-resistant layer. The wear mechanisms of the wear-resistant layer are abrasive wear and adhesive wear.
