Abstract
In this present research work the solid particle erosion test carried on uncoated samples (Ti-31), and HVOF sprayed 10%Al2O3 -CoCrAlTaY on Ti-31 are made. Erosion test are done with impact angles of 30º, 60º and 90º. Solid particle erosion studies were carried out using air jet erosion test rig as per ASTM G76-02 standard.All the three angles of uncoated alloys exhibit erosion damage under ductile mode and less amount of erosive loss compared HVOF coated samples. The HVOF sprayed coated Ti-31 at various impact angles is brittle mode. The mechanism of material removal during erosion of brittle materials is explained by using SEM micrographs.
