Abstract
The profiles of individual tracks were experimentally studied considering the powder flow rate, nozzle speed and temperature when creating a coating from a monometallic aluminum powder, a mixture of two monometallic powders of the aluminum-nickel and nickel-titanium systems, as well as composite powder from a mixture of monometallic powder of aluminum and corundum. Aluminum and nickel powders were chosen as the investigated ones, since they are the basis for most functional coatings. The dependence of the track profile on the scanning speed is established, the step between the tracks is determined, which ensures uniform coverage.
