Research on Self Repairing of the Remanufacture Coating Based on Shape Memory Alloy

Shape memory alloy is getting more people's attention as a new functional material with its particular shape memory effects and super-elasticity.The working principle of SMA and its classification are described,the results at home and abroad has been made of SMA and for monitoring the status and the self-healing principles and status to be introduced.The changes of mechanical properties on the SMA with temperature,stain,amplitude,and the relationship between the axial stain and resistance change rate of the alloy at room temperature are investigated,which will provide theoretical support for its application on the self-healing.Moreover,its applications on remanufacture coating self-healing are prospected and problems to be solved are analyzed.
