Abstract

An experimental investigation was undertaken to study the Cobalt-based Stellite 6, powder deposited on SS 304 stainless steel substrate without any intermittent layer using an atmospheric plasma spray deposition process by varying the thickness of coating in the range of 74 µm, 128 µm, and 215 µm. The effect of coating thickness on metallurgical properties and corrosion resistance behavior was investigated. Optical microscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDS) were employed to study the morphology of Stellite 6 coating. X-Ray Diffraction was used for structural analysis and to identify the phase formation. It was observed that the sample with 128 µm coating thickness provides the best result concerning microhardness and microstructure characteristics whereas the sample with 215 µm coating thickness provides the best corrosion resistance property. The reasons for the deviation were investigated and the factors responsible for the deviation were assigned in this investigation.

大气等离子喷涂Stellite 6粉末对AISI 304不锈钢的冶金性能和腐蚀性能的实验研究

采用常压等离子喷涂工艺，在74µm、128µm和215µm范围内改变涂层厚度，在SS 304不锈钢基体上沉积了无间歇层的钴基Stellite 6粉末。研究了涂层厚度对合金冶金性能和耐蚀性能的影响。采用光学显微镜、扫描电镜(SEM)和x射线能谱仪(EDS)对Stellite 6涂层的形貌进行了研究。x射线衍射用于结构分析和确定相的形成。结果表明，涂层厚度为128µm的样品在显微硬度和微观结构特征方面表现最佳，而涂层厚度为215µm的样品在耐腐蚀性能方面表现最佳。对偏差的原因进行了调查，并对造成偏差的因素进行了分配。
