Resumen

This study aims to enhance the corrosion performance of cold-sprayed titanium/baghdadite (Ti/BAG) bio-composite coatings. Laser post processing was performed to reduce porosity and improve mechanical properties. The process parameters for laser treatment of cold-sprayed coatings were verified experimentally using scanning electron microscopy (SEM) and a thermal imaging camera. The laser-treated coatings are analyzed with SEM, energy-dispersive spectroscopy (EDS), ImageJ software, and X-ray diffraction (XRD). Furthermore, electrochemical analysis of the laser-treated and as-sprayed coatings was conducted in Ringer?s solution. The results of this study revealed that laser treatment helps significantly in enhancing resistance to corrosion for Ti/BAG composite coatings in a Ringer?s solution. The reduction in porosity and surface roughness is ascribed as the reason for their superior performance relative to as-sprayed coatings.
