Abstract

Cleaning is an important procedure of used parts remanufacturing process and the paint-removal on the surface of used parts is a difficulty during cleaning process. The surface paint of three materials cast iron HT250, cast steel ZG270-500, and carburizing and quenching steel 20CrMnTi were cleaned by high temperature decomposition process in this paper. Before and after cleaning, the dimensional accuracy, microstructure and hardness of the three materials were compared and analyzed. The results showed that high temperature decomposition has no effect on dimensional accuracy, microstructure and hardness of cast iron and cast steel. However, the microstructure of the carburizing and quenching steel has a phase change, and the hardness decreases sharply. Therefore, it is concluded that high temperature decomposition process is an effective method removing paint on the surface of casting iron and cast steel metal used parts, but not for carburizing and quenching steel.
