Experimental study on Laser Metal Deposition of FGMs with Ultrasonic Vibration

摘要：

　　Referring to the ultrasonic vibration effect on casting,welding and laser cladding,the paper demonstrates the feasibility that it can be also used in Laser Metal Deposition(LMD)of titanium alloy to protect the defects such as crack,pore and oxidation and refine the grain size and improve the distribution uniformity of solidified structure.So the paper applies ultrasonic vibration system to fabricate the functionally graded materials(FGMs) samples and analyses its effect on the specimen microstructure and mechanical property by experiments.The results show that ultrasonic vibration can suppress the formation of pore,refine the grain and make the TiC hard phase more homogeneous in the FGMs parts,which is also indicated by the microhardness tests.
