摘要：

An enamel coating was prepared on TC4 ELI titanium alloy surface by using slurry sintering process, and the surface three-dimensional morphology, grinding crack morphology, microhardness and the tribological behavior of the coating and bon-ding strength between the coating and substrate were characterized by means of atomic force microscopy (AFM), scanning electron microscopy (SEM), microhardness test, friction and wear testing machine and thermal shock method, respectively. The morphology of the coating and matrix before and after wear was comparatively analyzed, and the wear mechanism was discussed. The results show that the structure of the coating is compact and well combine with matrix. The thickness of the coating is about 30 μm, and it is uniform and smooth. Compared to matrix, the hardness of the coating improves obviously. Under the condition of dry friction and wear, the wear mass loss of the coating is little, and is only one quarter of the base metal. The wear rate of the coating is about 29.6% that of the matrix. The coating shows excellent wear-resistance. The wear mechanism of the TC4 ELI titanium alloy is the adhesive and abrasive wear, while the enamel coating is the abrasive wear. © 2016, Materials Review Magazine. All right reserved.
