Abstract

The influence of pulse current density on the mechanical and oxidation properties of Ni-TiN composite coating was studied. The composite coatings were deposited by using electrodeposition technique with varying pulse current density of 0,4 mA/mm2, 0,6 mA/mm2, dan 0,8 mA/mm2. Microwave-induced heating process was used as a novel approach to investigate the oxidation behaviour of the composite coatings. The surface morphology and composition of the coatings were characterized by using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy, respectively while the coating hardness was tested by using Vickers microhardness test. The effect of microwave-induced heating on the mechanical and oxidation behaviour of composite coating is discussed.
