“…Besides the APS, spraying parameters affect the microstructure and properties of the coating, which is decisive for the operation performance of coatings in specific applications [10,11]. The literature presents the typical operational performance of ceramics evaluated under dry sliding wear conditions [12,13]. However, as far as the authors' knowledge is concerned, there is no report on the water environment sliding wear of Al 2 O 3 -13% TiO 2 (AT13) coatings.…”

Atmospheric plasma spraying is an up-to-date and systematically developed technology. One of the crucial ideas is injecting the sprayed feedstock powder internally or externally into the plasma arc. The spraying parameters affect the microstructure and properties of the coating, which is decisive for the operation performance of coatings and specific machine components. This paper investigates the effect of atmospheric plasma spraying parameters, namely the feedstock injection mode and the spray distance, on cavitation erosion and wet environment tribological behaviour of Al2O3-13% TiO2 coatings. The internal and external injection spraying mode, constant spray velocity (500 mm/s), and two spray distances to the substrate, namely 80 mm and 100 mm, were employed. The microstructure, porosity and hardness of the deposited coatings were studied. Cavitation erosion resistance was estimated using the ASTM G32 method. The sliding wear resistance has been estimated in the distilled water environment using the ball-on-disc apparatus. The results indicate that the internal injection supports the cavitation erosion resistance and the aquatic sliding wear. The coating fabricated with the 80 mm spray distance using the internal method is characterized by the smallest wear and the highest anti-erosion performance. A shorter spraying distance indicates greater coatings uniformity, while the increasing distance reduces the hardness and porosity, which are beneficial for the performance of the coatings. The main wet sliding wear mechanism has been fatigue-induced material detachment, while the cavitation erosion mechanism depends on the brittle fracture resulting in material detachment and pitting.
