This paper demonstrates the characterization of High Velocity Oxygen Fuel (HVOF) sprayed NiGrFeS coating on SAE 1008 cold rolled steel as a substrate to improve the surface properties for tribological applications. A combination of characterization techniques, such as XRD and SEM/EDAX procedures, have been used to evaluate the coatings as well as for mechanical and microstructural characteristics. Additionally, the porosity, microhardness, coating thicknesses, and coating density have been arrived at a view to obtain structure property co-relations. The HVOF overrides other thermal spray processes in terms of specific advantages of getting superior properties. Being a new development in the family of spray technology, the various issues such as coating quality, surface characteristics and other associated factors are being addressed and reported with the research work carried out. It is observed from the data the microhardness values have decreased across the depth of the coatings. [ABSTRACT FROM AUTHOR] |
