Influence of Titanium Additions on The Electrochemical Behaviour of NiCr/Ti Laser Cladded Coatings

In this research, the electrochemical evaluation of NiCr/Ti laser cladded coatings in simulated polymer electrolyte membrane fuel cells (PEMFCs) environment was investigated. The Laser Cladding technique used to develop protective on mild steel substrate using NiCr-based powders mixed with 12.5, 15, 17.5 and 20 wt.% Ti additions. samples were tested at room temperature Na2SO4 0.1M + 0.1 ppm F-. potentiodynamic polarization curves are presented before after subjected accelerated stress tests, for 6 hours each, +0.736 V (cathodic environment) -0.493 (anodic environment). Afterwards, scanning electron microscopy (SEM) investigate effect addition terms morphology. Energy-dispersive X-ray spectroscopy (EDS) performed chemical surface corrosion tests.
