Abstract:

Purpose: The purpose of this study was to investigate the microstructure and the properties of the Ti coatings cold sprayed using spheroidal powder on the Al 7075 alloy. Design/methodology/approach: The Ni powder with irregular shape of grains was applied in the cold spraying process. The coatings were sprayed by means of a Impact Innovations 5/8 system with of nitrogen as process gas. Findings: The high kinetic energy of titanium particles causes their significant deformation and splats strongly adhere to the substrate and to each other. Cold sprayed titanium coatings exhibit negligible porosity and different mechanical properties caused by varying deformation degree of titanium powder. There were no phase changes in titanium powder during the spray process, and the coating consist of crystalline titanium. Practical implications: Titanium and its alloys have unique properties such as a high strength to weight ratio, excellent corrosion resistance and bio-compatibility. These features make it a material that is ideally suited for use in the aerospace, medical, and corrosive industries. Originality/value: The main advantage of cold spraying is elimination of influence of temperature on the particles of the coating material and the substrate that occurs in conventional thermal spraying methods. Therefore, the properties of such formed coatings are not available in other technologies.
