Nanostructured materials and coatings are a main subject in research and development thanks to their good physical and mechanical properties compared to crystalline materials [1]. Cold Gas Spraying (CGS) is a low-temperature method with deposition carried out in the solid substrates relative to conventional thermal spray [2]. The deposition is achieved through powder acceleration to supersonic velocities in the de Laval type nozzle [3] (Fig. 1). The technique was developed in the Institute of Theoretical and Applied Mechanics of the Russian Academy of Science in Novosibirsk [3]. The coating materials are injected into the carrier gas stream in nanopowder form at the inlet of the de Laval nozzle. It is accelerated in gas stream and propelled to the substrate with high velocities. In the special chamber gas is heated to temperature lower than the powder material’s melting point, before entering the nozzle [4]. Only particles which reach the velocity higher than the critical velocity could be deposited onto a substrate [5]. The low-temperature method, the very short time scales and the use of more or less inert carrier gases (nitrogen, helium) make the Cold Gas Spray technique useful for applications where it is vital to avoid oxidation, maintain stoichiometry and to retain properties of the powder in the coatings. In comparison to conventional thermal spraying, CGS has the another advantage of being simple to implement [6]. In the coatings titanium was used as a plastic binder. The hard titanium carbides improve wear resistance. The aim of this work is to present the results of microstructural and compositional investigation into Ti/TiC coatings deposited by means of supersonic spray[...]
