| In this paper the results of cavitation erosion test of ceramic coatings are presented. The Al2O3–13% TiO2coatings were manufactured by powder atmospheric plasma spraying. The plasma spray experimental parametersincluded two variables: (i) spray distance varying from 80 to 100 mm and (ii) torch linear speed varying from300 to 500 mm/s.The as sprayed surface roughness was measured. The coatings structure was investigated usingSEM. Porosity was investigated according to the ASTM E2109-01 Standard procedure. Additional microhardnessmeasurements were conducted. The cavitation tests were carried out on vibratory test rig according to the ASTMG-32 standard regarding to the stainless steel (grade 304) reference sample. The cavitational worn areas wereexamined using SEM microscopy and roughness measurements. The influence of coatings microstructure andmicrohardness on the cavitation erosion resistance was investigated. The coatings microstructure was stronglydependent on spray distance as well as torch linear velocity. Decrease of the hardness was a result of less compactstructure and lower degree of well molten particle. On the contrary, the best cavitation erosion resistance wascharacteristic for coatings which have quite good and compact structure but on the other hand the heat flux waslower. Higher heat flux caused thermal stresses, which were visible as cracks in the structure. Moreover, the type ofthe structure was important because from the point of view of the cavitation erosion resistance, lamellar architectureis more preferred than the columnar one. Finally, the structure type was linked to the process parameters. |
