States and Prospects of Crack Arrest and Healing Technology

doi:10.3901/JME.2016.07.122

Abstract

Abstract: Crack is the main failure form of mechanical products. Preventing the micro crack growth or healing the micro crack can not only ensure the mechanical products running safely, also extended their service life. Domestic and foreign research status of crack arrest and healing are reviewed, the application of electro pulsing in material processing is introduced, and the high intensity electro pulsing as the input of transient energy on crack arrest and healing is highlighted. With consideration of the features of remanufacturing products, electro pulsing treatment on crack arrests and healing in remanufacturing is put forward. According to the literature for nearly forty years, it prospects developing trends of crack arrest and healing in remanufacturing, and proposes the development strategies and suggestions.
