... of erosion mechanisms that are dependent on the particles’ kinetic energy. Microscopic examinations of damaged surfaces revealed that extruded lips indentation was the major mechanism of erosion, which occurred at 5 m/s speed and 30-deg impingement angle. Ploughing was proved that it was the predominant...

... morphology features revealed that the predominant erosion mechanism was fatigue failure, irrespective of the temperature. Cavitation is defined by the ASTM standard ( 1 ) as the formation and subsequent collapse of cavities or bubbles that contain vapor or mixture of vapor and gas within a liquid...

... of NiCrAlY coating as compared to Ni - 20 Cr coating under the tested conditions. Erosion mechanisms of plasma sprayed coatings are discussed. Two types of alloy powders, NiCrAlY and Ni - 20 Cr , were used in the study (Table 1 ). The NiCrAlY is also used as a bond coat...
