Gd5Si2Ge2／Gd室温磁制冷复合材料激光熔覆成形工艺研究

Study on the Laser Cladding Process of the Room-temperature Magnetic Refrigerating Materials Gd5Si2Ge2/Gd

摘要:

就Gd5Si2Ge2化合物的激光熔覆成形工艺作了初步研究。实验表明：Gd5Si2Ge2在Gd基体上可以实现良好的冶金结合。在最小厚度不小于1mm的基板上，控制激光参数可以使熔覆层的稀释度保持在10％左右。

Abstract:

Some initial researches on the laser cladding process of GdGd_5Si_2Ge_2/Gd compounds were made in this paper.Experiment results indicate that good metallurgical bonding can be obtained between the Gd_5Si_2Ge_2 alloy and Gd base;on the Gd base whose minimal thickness is not less than 1mm,the dilution of t he cladding can be kept about 10%.
