| Abstract | ||||
| Corrosion and erosion-corrosion behavior of Al-6061 was investigated. Tests were performed in 3 wt. % NaCl solutions with and without sand particles using the rotating sample method at 5.65 and 11.3 m/sec. Both the tests showed an increased weight loss with test duration. In erosion- corrosion tests, weight loss of the samples was accelerated by the impingement of the electrolyte at corroded sites leading to easy removal of corrosion products from the surface. The presence of sand particles in the electrolyte accelerates the process of material removal due to rapid formation of pits and craters. The effect of velocity and heat treatment on the mechanism of erosion- corrosion was investigated. An analysis of the affected surfaces of typical specimens by SEM enabled the understanding of the operating wear mechanisms under specific test condition. | ||||
