In-Situ Raman spectroscopic analysis of surface oxide filma on Ni-base alloy/LAS dissimilar metal weld interfaces

摘要

In, this work, a hydrotherral cell for in-sin surface xoide analysis using Raman spectroscopy were designed and assembied. And the preliromary results of the Raman soectroscopic analysic with reference powders as well as DMW samples in aqueous conditions are good agreement with the previous data.
