Optimization of the coating process by cold gas dynamic spraying applied to production conditions of Ni–Ti and Ni–Al systems

This study developed practical recommendations for using the method of cold gas dynamic spraying to obtain functional coatings in a production environment using powders of nickel, titanium and aluminum of the grades: PNE-1 (Ni), PTOM-1 (Ti) and PA-VCh (Al). The temperature and speed parameters of the process were optimized using mechanical mixtures (Ni + Ti) and (Ni + Al) as an example. High adhesion of the coating and coefficient of powder use were ensured with maximum productivity at the DIMET-403 installation.
