Abstract
The present work aims at the development of an energy efficient and eco-friendly approach for the deposition of TiCrN composite coating. The study describes the deposition, characterisation and corrosion resistance of the composite coating. The methods of evaluation include assessment of colour and uniformity by physical and visual observations, adhesion by pull-off adhesion test, morphological features by optical and scanning electron microscopy, and chemical composition by energy-dispersive X-ray analysis. The corrosion resistance of the coatings in 3.5 % NaCl was evaluated by potentiodynamic polarisation studies. The finding of this study reveals that the adhesion of the coating on uncoated steel and adhesion of paint film on TiCrN composite-coated steel were found to be good. A potentiodynamic polarisation result confirms that TiCrN composite coating offers a better corrosion resistance than uncoated steel.
