Abstract

Refractory ceramic coatings are desirable for their physical and chemical natures, which make the coatings suitable for many applications involving wear and corrosion environments. The synthesis of a refractory ceramic coating on a metallic substrate can be achieved using laser surface engineering. In this article, laser surface engineering is demonstrated for the synthesis of a TiB2 coating on plain carbon steel. The predeposited layer of a TiB2-based precursor in an organic vehicle treated with a laser produced a variety of microstructures within the modified surface that are unattainable with conventional coating methods.
