超音速火焰喷涂制备WC-Cr3C2-Ni涂层工艺参数的优化
Optimization of Spray Parameters in Preparation of WC-Cr3C2-Ni Coating by High Velocity Oxygen Fuel Spraying
摘 要
采用超音速火焰（HVOF）喷涂在Q235钢表面制备了WC-Cr3C2-Ni涂层，以喷涂距离、氧气流量、煤油流量为变量，设计了三因素三水平正交试验，并对涂层孔隙率、显微硬度和综合指标进行了评分，获得了最佳工艺参数组合。结果表明：WC-Cr3C2-Ni涂层的最佳工艺参数为氧气流量1 740 scfh （49 242 L·h-1）、煤油流量7.0 gph （26.495 L·h-1）、喷涂距离330 mm。

Abstract
WC-Cr3C2-Ni coatings were prepared by high velocity oxygen fuel (HVOF) spraying on the Q235 steel. The orthogonal experiment of three factors and three levels was designed by regarding spraying distance, oxygen flow rate and kerosene flow rate as variables, and the porosity, hardness and comprehensive index of the coatings were graded to obtain the best combination of spray parameters. The results show that the optimal spray parameters of WC-Cr3C2-Ni coating were 1 740 scfh (49 242 L·h-1) for the oxygen flow, 7.0 gph (26.495 L·h-1) for the kerosene flow and 330 mm for the spray distance.
