Abstract
When solid particles in liquid impact on the material surfaces, part of the surface materials is damaged or removed. This phenomenon is called "Erosion". Erosion raises some serious problem with the pipe bend parts and the valves of piping concerning the mixed tow-phase flow of gases and solid. Paying attention to the results obtained until now, we investigated the wear characteristic from the viewpoint of the shape of solid particles. Concretely, the erosive wear characteristic was evaluated by using the high chromium steel by the conventional experimental technique employed previously.
