A study on the Fabrication of Graded-Boundary Ni-Cr/Steel Material by Laser Beam
레이저빔에 의한 계면경사 Ni-Cr/steel 재료 제조에 관한 연구
Abstract
For a development purpose of thick metal / metal Graded-Boundary Materials(GBM), a basic research on the fabrication of Ni-Cr/steel GBM was carried out by a laser beam and its mechanical properties and thermal characteristics were investigated. In order to produce a compositionally graded boundary region between substrate steel and added Ni-Cr alloy, a series of surface alloying treatments was performed with a high power CO
