Wear and Corrosion Characteristics of AISI 304 Stainless Steel

This book addresses an effort is made to deposit Cobalt-based Stellite 6 powder having a regular spherical shape with diameters ranging between 15 m to 45 m on an AISI 304 rolled stainless steel substrate without any bond coat.The atmospheric plasma spray deposition process was adopted with additive manufacturing for three different types of coating thicknessin the range of 74 m, 128 m, and 215 m..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 m coating thickness provides the best result concerning microhardness and microstructure characteristics whereas the sample with 215 m coating thickness provides the best corrosion resistance property. The reasons for the deviationwere investigated and the factors responsible for the deviation were assigned in this investigation.
