Abstract:

The study analyses the tribological properties of a composite plasma sprayed with Al 2 O 3 -3TiO 2 mixed in various proportions with CaF 2 , which is known as a solid lubricant. The coatings were plasma-sprayed in air and were tested using a pin-on-disc tribological set-up. The tests enabled to study their wear resistance and determine the coefficient of friction on the basis of friction force obtained in the course of continuous measurement at a set load. Experiments were optimized by the use of the two-level experiment design aimed at finding the optimal content of CaF 2 in the composite. The influence of the spraying parameters on the coefficient of friction, hardness and surface roughness was determined by means of regression analysis. Metallographical studies of the plasma-sprayed composite were conducted with the use of a scanning microscope with an energy dispersion spectrometer (EDS).
