Composite coatings are fabricated by laser cladding of titanium alloy Ti-6Al-4V with graphite and silicon mixed powders. X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) indicate that the coatings mainly consist of pre-eutectic TiC and eutectic Ti5Si3 compounds. Test results show...

In-situ synthesized TiB2 particles reinforced Ni-base composite coatings with different compositions were fabricated on medium carbon steel using laser cladding. Cracking behavior in different coatings was studied by microanalysis. Results show that the coating quality is good with optimal laser...

Purpose – Refurbishing may be the most practical approach under the low volume production. This effort aims to achieve robotic laser cladding with the main purpose of achieving maximum processing flexibility, predictably high quality, lower maintenance and operating costs. This study aims to...
