The use of Titanium alloys (Ti6Al4V) is highly evident in applications such as aerospace, automobile, marine and petrochemical environments owing to their outstanding specific strength to weight ration and good corrosion properties. Although they have high strength useful for fabrication of engineering components and movable parts in a mechanical system, Ti6Al4V are restricted to non-friction applications as a result of their low hardness and poor wear resistance. In this work, TiNi intermetallic hard coatings on Ti6Al4V alloy via coaxial laser cladding method. The effects of laser processing parameters on morphological evolution, microhardness and electrochemical behaviour were studied. The phase present and microstructural evolution were characterized using X-ray diffractometry (XRD) and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS) respectively. The corrosion behaviour of the synthesized hard coating was evaluated using potentiodynamic polarization technique in 0.5M H₂SO₄. The microstructures showed no evidence of porosity, crack or initiation of stress.
