Erosion Study of AM355 and Al2O3 Ceramics.

Abstract

The need for the knowledge and better understanding of material erosion behavior is necessary for the use of these materials in future helicopter engines with confidence. The present experimental investigation presents a detailed study of the erosion behavior of a typical ductile material (steel AM355 alloy) and a nonductile (brittle) material Aluminum oxide. The experimental results show the influence of the particle size, particle velocity and temperature on the erosion rate. Electron micrographs of the eroded surfaces under various conditions are presented and compared. Empirical correlations for the erosion results are also presented. Keywords: Erosion ductile material, Erosion nonductile material, steel, alloys, ceramic materials, helicopter engines.
