Abstract Kerosene-fueled high velocity oxy-fuel (HVOF) spray was employed to deposit commercial Ti2AlC MAX phase powders onto Inconel 600 substrates. After optimizing three process parameters including flow rates of kerosene and oxygen as well as spray distance, a dense Ti2AlC coating with a very low decomposition was obtained. Using Rietveld phase analysis of the X-ray diffraction pattern, the weight percentage of Ti2AlC in the coating was determined to be 53.0%, which is not only far better than the coating deposited by plasma spray, but also is comparable with the optimum Ti2AlC coatings sprayed by H2-fueled HVOF and cold spray. This optimized Ti2AlC coating was further analyzed by a variety of techniques to probe its surface chemistry, morphology, cross-sectional microstructure, mechanical properties and salt fog corrosion resistance.

Ti 2 AlC MAX 相粉末的煤油燃料高速氧燃料 (HVOF) 喷涂

摘要 采用煤油为燃料的高速氧燃料 (HVOF) 喷雾将商用 Ti2AlC MAX 相粉末沉积到 Inconel 600 基材上。在优化包括煤油和氧气的流量以及喷涂距离在内的三个工艺参数后，获得了分解率非常低的致密 Ti2AlC 涂层。通过X射线衍射图的Rietveld相分析，确定涂层中Ti2AlC的重量百分比为53.0%，不仅远优于等离子喷涂沉积的涂层，而且与最佳Ti2AlC涂层相当以 H2 为燃料的 HVOF 和冷喷涂。这种优化的 Ti2AlC 涂层通过各种技术进一步分析，以探测其表面化学、形态、横截面微观结构、机械性能和耐盐雾腐蚀性能。
