| 摘 要： | 超音速火焰喷涂具有粒子飞行速度高、涂层质量好、沉积速度快、材料选择性好以及与基体的结合强度高等优点。冲蚀是水轮机过流部件、轮船螺旋浆、泥浆泵及钻杆等的主要失效形式之一。HVOF技术制备的金属陶瓷涂层因其能显著提高金属零部件的耐冲蚀性能而受到广泛应用。本文对国内外HVOF喷涂金属陶瓷涂层的冲蚀失效行为进行综述,系统归纳了冲蚀颗粒粒径、冲蚀速度、攻角等外部因素及涂层的结合强度、孔隙率、涂层颗粒尺寸、碳化物颗粒的大小等内部因素对HVOF喷涂金属陶瓷涂层冲蚀失效行为的影响机制。并指出综合评价外部服役条件和自身性能参数对涂层冲蚀失效行为的作用机理是本领域今后研究的重点方向之一。

| Abstract: | High velocity oxygen fuel technology has the advantages of high particle velocity, good coating quality, fast deposition speed, good material selectivity and high bonding strength with the substrate. Erosion is one of the main failure mode of the hydraulic turbine parts, ship propeller, mud pump and drill pipe. The cermet coating prepared by HVOF technique can significantly improve the erosion resistance of metal parts. The research status of erosion failure behavior of HVOF spraying cermet coating were reviewed. The influence of external factors such as erosion particle size, impact velocity, angle as well as the internal factors such as porosity, bonding strength between coating and substrate, powder particle size and the carbide particle size on the erosion failure mechanism of HVOF sprayed cermet coating was summarized. It was pointed out that the influence mechanism of external conditions and performance parameters of the coatings on the erosion failure behavior is one of the key directions for future research. |
