“…In this process, laser is used to heat the deposition zone in order to soften both substrate and powder particles thus allowing formation of a coating at a much reduced impact velocity of particles [26,27]. In the research of Lupoi [28], Bray [27], Luo [29] and Jones [30], Stellite 6 was coated on a steel substrate and tungsten was deposited onto a molybdenum substrate with SLD technique. Although SLD technique has been proposed for depositing hard materials [31], the SLD process has not been well studied, in particular, for hard Ni-based alloy as binding matrix.…”

Cold spray (CS) is an emerging materials deposition technique in which metallic particles are accelerated to a high velocity in a supersonic gas flow and then impinged onto a substrate to form a coating at a temperature well below the melting point of sprayed materials. The coating microstructure and properties are greatly influenced by particle preheating and substrate softening. This article presents a study of CS process of copper powder, with assistance of synchronous laser irradiation. The influence of synchronous laser irradiation on the Cu coating characteristics was investigated. The results show that the coating surface with laser irradiation is smoother than that without laser irradiation. The peak coating thickness is increased by about 70% as synchronous laser irradiation is employed, indicating an improvement in deposition efficiency. It is also found that with synchronous laser irradiation the coating is denser and the coating-substrate interfacial bonding is better as compared with that without laser irradiation. Moreover, the EDS and XRD analyses find Cu oxidation occurrence in the SLD coating, but the oxide is trivial. The aforementioned improvements on the coating largely arise from particle preheating and substrate softening by synchronous laser irradiation in the CS process.

“…Matthew et al [8,9] successfully combined laser cladding with cold spraying together to prepare high-density coatings consisting of Ti and Ti alloy, and used cold N 2 as a carrier gas to reduce the cost of cold spraying. The supersonic laser deposition (SLD) method offers many advantages by combining laser with cold spraying, in particular, the use of a laser to control the deposition temperature, which allows hard materials, such as Stellite 6 and carbide [10,11], to be deposited while maintains the key advantages offered by solid-state cold spraying and replaces high cost helium with nitrogen. Moreover, the high-speed impact of particles on the substrate produces severe plastic deformation, resulting in a good bonding of the coating and the substrate.…”

Ni60-WC particles are used to improve the wear resistance of hard-facing steel due to their high hardness. An emerging technology that combines laser with cold spraying to deposit the hard-facing coatings is known as supersonic laser deposition. In this study, Ni60-WC is deposited on low-carbon steel using SLD. The microstructure and performance of the coatings are investigated through SEM, optical microscopy, EDS, XRD, microhardness and pin-on-disc wear tests. The experimental results of the coating processed with the optimal parameters are compared to those of the coating deposited using laser cladding.
