Abstract
The possibility of using the low-pressure cold gas spraying (LPCS) method to create composite coatings hasbeen known and used for a long time. This method makes it possible to create coatings from physically andchemically different powders and to regenerate components damaged during operation. Composite coatingsof titanium and aluminium at different weight concentrations were selected for the study. The research wasconducted to optimise the influence of the chemical composition of the composite coatings on their tribologicalproperties. This paper presents the results of tribological wear testing of composite coatings applied using thelow-pressure cold gas spray (LPCS) method. Wear resistance tests were performed using the ball-on-platemethod in reciprocating motion using a steel ball. Tribological testing of the coatings included determiningthe effect of contact force on wear and the value of the kinetic coefficient of friction of the friction pairs tested.The study determined the optimum chemical composition of the Ti-Al composite coatings to improve wearproperties.
