D213 Effect of Impact Angle on Liquid Droplet Impingement Erosion of Sl5C Carbon Steel

Abstract

For piping systems in power plants ， low carbon steels are used 」 n this study ， the effect of impact angle on liquid droplet impingement erosion of S l 5C carbon steel is discussed by comparison with that of pure aluminurn ． It was found that the impact angle dependency was evaluated in tems of Vsin 0 ( 7； impact velocity ，〃：impact angle ) ． The threshold flow velocity was obtained ， below which no erosion occurred ． The norma 且component ofthe threshold velocity increased with the decreased impact angle ， Key Mords ： Erosion ， Low carbon stee1 ， Liquid Droplet ， Impact angle ．
