Popis: | The paper presents the results of experimental studies of the solid particles erosion resistance of titanium Ti-6Al-4V alloy samples, made using additive technologies with different types of protective coatings based on chromium and carbide chromium (Cr-CrC) and DLC (Diamond-Like-Carbon). By means of complex of laboratory equipment, the characteristics of the formed types of coatings were determined, such as thickness, composition, microhardness. Studies of the resistance to impact of solid particles were carried out on an experimental test stand for the study of solid particles erosion of materials and protective coatings at an air-abrasive flow rate of 170 m/s, a flow angle of attack of 30 ° and a sample temperature of 25 °C. It has been established that an ion-plasma coating based on Cr-CrC, 7–9 μm thick, increases the abrasion resistance of titanium alloy samples made using additive technologies not less than 1.5 times. |
