英文摘要	Brittle intermetallic compounds in brazing joints of titanium and steel easily worsen their weld organization and mechanical properties. In order to solve this problem, a series of contrast tests in which the Ni layer was plated on the matching surface of base metal or not were conducted and the influencing mechanism of Ni clad layer on the atomic diffusion behavior, microstructure and mechanical properties of the brazing joint were investigated. The results show that the Ni layer blocks the atom diffusion of brazing joints; however, the degrees of obstruction are different among Fe, Ti and other atoms. The difference is closely related to the physical location of Ni layer in the joint region. The obstruction of Ni layer alters osmotic concentration of the atoms, slows down the metallurgical reaction degree, and reduces the content of brittle intermetallic compounds. Consequently, Ni clad layer can effectively improve the microstructure and mechanical properties of the brazing joints. © 2016, Science Press. All right reserved.
