Abstract
The role of particle size and solids concentration on the slurry erosion of a stainless steel was studied with base in laboratory tests and data from field inspections of two Pelton turbines. The slurry for the laboratory tests was composed of water and SiO2 sand particles with mean diameter ranging from 50 to 655â¯Î¼m and solids concentrations up to 1200â¯mgâ¯lâ1. The wear rate increased linearly with solids concentration within the range studied, while the sensitivity of the surface to changes in erosive particle size decreased with the particle size. A critical particle size range for the moderate-to-severe wear regime transition was found, which is practically unaffected by the variety of solids concentrations considered in this study.
