“…Precipitation and growth of secondary phases from the coating matrix are highly affected by reference temperature at which cooling occurs after laser deposition. This is in support of action of higher heat input as stated by [32]. Higher reference temperatures are obtained from higher laser powers, while large temperature gradients between the coating and the bulk substrate are associated with increased laser powers.…”

Metallic Ti-Co binary coatings were fabricated on titanium alloy (Ti-6Al-4V) substrate by laser surface cladding technique using a continuous wave RofinSinar 4 kW Nd: YAG laser. The influence of laser power on microstructure, hardness and tribological performance of Ti-Co laser clad coatings on titanium alloy (Ti-6Al-4V) was examined. Laser powers of 750 and 900 W were varied with constant scan speed of 1.2 m/min. A beam size of 3 mm and argon shield gas flow rate of 1.2 L/min were set as the operating laser parameters. Phase identification and morphological studies of the coatings were carried out using X-ray diffractometry (XRD) and scanning electron microscopy (SEM), respectively. Based on the results of laser process optimisation, it was observed that both laser powers produced clad coatings with good metallurgical bond with no cracks or pores in the coatings. With respect to the substrate (Ti-6Al-4V), the microstructure, hardness and friction/wear behaviour of Ti-Co coatings on Ti-6Al-4V substrate were enhanced obviously.

“…To improve these properties, nickel matrix composite coatings with different reinforcements have been developed. Among various reinforcing ceramic particles, TiC has been particularly more attractive due to its low density, high hardness and melting point, high temperature strength and good wear resistance [8,9].…”

NiMo-5%TiC, NiMo-15%TiC, and NiMo-25%TiC coatings were prepared on GCr15 steel by laser cladding (LC). The microstructure and the phases of the obtained coatings were analyzed using ultra-depth-of-field microscopy (UDFM) and X-ray diffraction (XRD), respectively. A ball-on-disk wear test was used to analyze the friction-wear performance of the substrate and the NiMo-TiC coatings under grease-lubrication condition. The results show that the grain shape of NiMo-TiC coatings is dendritic. The wear resistance of NiMo-TiC coatings is improved by the addition of TiC, and the depths of the worn tracks on the substrate and on the NiMo-5%TiC, NiMo-15%TiC, and NiMo-25%TiC coatings are 4.183 μm, 2.164 μm, 1.882 μm, and 1.246 μm, respectively, and the corresponding wear rates are 72.25 μm3/s/N, 32.00 μm3/s/N, 18.10 μm3/s/N, and 7.99 μm3/s/N, respectively; this shows that the NiMo-25%TiC coating has the highest wear resistance among the three kinds of coatings. The wear mechanism of NiMo-TiC coatings is abrasive wear, and the addition of TiC plays a role in resisting wear during the friction process.
