Effects of Permanent Magnet Electromagnetic Stirring on TA15 Laser Metal Deposition

Abstract:

Electromagnetic stirring (EMS) is an important method to homogenize the hard phase of the cladding layer. Rotary Permanent magnet electromagnetic stirring (PEMS) is adopted during the experiment. The changes of heat affected zone, solidification character, microstructure and hardness of TA15 Laser Metal Deposition (LMD) based on PEMS have been researched during the experiment. The results show that the PEMS can refine the grain, homogenize the microstructure, eliminate the disfigurement and enhance the hardness.
