The microstructure of the specimens were examined using a range of characterization techniques including XRD analysis, SEM, and EDS interfaced to SEM. The as-sprayed coatings are characterized with respect to microstructure and mechanical properties. The porosity, surface roughness, coating thicknesses, density, and bond strength of coatings have been also evaluated. © 2021HVOF thermal sprayingMicrostructureNickel alloysSprayed coatingsSurface roughnessThickness measurementBoiler tube steelsCharacteristic and propertiesCharacterization techniquesHVOFHVOF coatingsMicrostructure characteristicsMicrostructures propertiesNi coatingThermalsprayXRD analysisSurface analysis
