浸渗法合金化纯钨表层的研究
Study on Infiltration Alloying of Tungsten Surface
摘要
Abstract
W-Ni-Fe alloying layer on tungsten was prepared by infiltration Ni-Fe melt. The micro-structures and the depths of alloying layer with different infiltration holding time were analyzed. Results showed that W-Ni-Fe alloying layer depths were 530μm and 700μm when the infiltration holding time was 10min and 20tnin, and the NiFe-rich phase region embedded in tungsten phase was very small. When the infiltration holding time increased to 30min and 40min, the W-Ni-Fe alloying layer depths were 750pm and 770pm, the NiFe-rich phase region significantly enlarged, and the shape of partial tungsten phase became spheroid. The forming mechanism of W-Ni-Fe alloying layer on tungsten was explained based on experimental results and W-Ni phase diagram.关键词
