在这项工作中，基于X220CrVMo13‐4冷作型钢的HVOF喷涂涂层应用于S235JR建筑用钢基体。通过光学显微镜（OM）和扫描电镜（SEM）分析了颗粒尺寸和喷涂参数对涂层微观结构的影响。在衬底材料和涂层之间的界面上进行了额外的XRD测量和显微硬度图。此外，还研究了颗粒尺寸对检测相和涂层孔隙率的影响。将结果与HIP生产的X220CrMoV13‐4参考样品进行比较。
Within this work, HVOF sprayed coatings based on X220CrVMo13‐4 cold work steel were applied to a S235JR construction steel substrate. The investigations focus on the influence of particle size and spray parameters on the coating microstructure, analyzed by means of optical microscope (OM) and scanning electron microscopy (SEM). Additional XRD measurements and micro hardness plots across the interface between substrate material and coating were carried out. Furthermore, the influence of particle size on the detected phases and coating porosity was studied. The results were compared with an X220CrMoV13‐4 reference sample produced by HIP.
