Experimental study on metal melt deposition

Metal melt deposition involves thermo-physical processes such as the formation, morphological evolution, flow and solidification of metal melts. According to the discontinuous characteristics of liquid metal flow, a metal melt deposition device was designed and developed. By studying the development process of metal melt deposition experimental platform and software control system, the key parameters (pulse pressure, melt temperature, substrate temperature, etc.) in the process of metal melt fluid deposition are controlled and monitored. The results show that the monitoring and control of the key parameters (scanning speed, melt temperature, substrate temperature, etc.) in the process of metal melt deposition is realized by this experimental device, which provides the necessary experimental software and hardware basis for the further study of melt deposition forming technology.
