The results of the investigation of the intermetallic Ni–Ti system coating obtained by the complex method of cold gas dynamic spraying and laser treatment are presented. The dependence of the coating charge composition on the initial powder composition is shown. Its structure, porosity, and microhardness are studied, and also the results of X-ray phase analysis confirming the presence of the intermetallic phase are presented. The microhardness is increased by more than a factor of 5 to 632 HV, and the porosity is decreased by a factor of 25 to 0.2%. Investigation of the substrate–coating boundary shows the presence of mutual diffusion.
