中文摘要：为了提高TC4合金表面的硬度和减磨性、优化工艺参数,采用多组工艺参数(不同功率、不同TiO_(2)粉末含量)在TC4板表面制备不同比例的Fe60-TiO_(2)复合涂层,分析了熔覆层宏观形貌、表面维氏硬度和减磨性。结果表明,当激光功率为500W、TiO_(2)质量分数为0.10时,熔覆层表面较平整;通过X射线衍射分析熔覆层生成较多Ti化合物,这些Ti化合物对提高熔覆层硬度和减磨性非常有利;熔覆层硬度比基体提高了约2.5倍;摩擦系数较基体相比有所降低,熔覆层的平均摩擦系数约为0.46。此研究结果对TC4钛合金表面熔覆Fe基复合涂层的硬度和减磨性工艺参数有一定指导作用。

外文摘要：In order to improve the surface hardness and wear reduction of TC4 alloy,Fe60-TiO_(2) composite coatings with different proportions were prepared on the surface of TC4 plate by using several groups of process parameters(different power and different TiO_(2)powder content).The macroscopic morphology,surface Vickers hardness,and wear reduction property of the cladding layer were analyzed.The results show that when the laser power is 500W and the mass fraction of TiO_(2) is 0.10,the surface of the cladding layer is smooth.According to the X-ray diffraction analysis,many Ti compounds are formed in the cladding layer,which is very beneficial to improve the hardness and wear reduction of the cladding layer.The hardness of the cladding layer is about 2.5 times higher than that of the substrate.The average friction coefficient of the cladding layer is about 0.46.The results have a certain guiding effect on the hardness and wear reduction process parameters of Fe based composite coating on TC4 titanium alloy surface.
