Laser surface processing of ultralight magnesium alloys

Abstract

for making the effort to participate in my qualifying examination. Second, I would like to express my appreciation to Machining Technology Group from Singapore Institute of Manufacturing Technology for providing me privileges to use their facilities and for providing great help through my study. I would like to thank Dr. Zheng Hongyu for his brilliant guidance and caring financial support. He opened up a whole new world of laser science to me. I am also grateful to Dr. Li Zhongli for her countless contribution to this work. Her great knowledge on lasers and ingenious experimental techniques has helped me numerous difficulties and guided me to become a skilled researcher. Third, I would like to thank the other great members of our research group for their nice friendship on my research work and life during the past four years.

Laser Brazing of Diamond Grits with a Ni-Based Brazing Alloy

“…The observation of the phase components and morphology of the compounds in the interfacial reaction region of diamond crystal and Cr-coating mentioned above gives some information on the relevant reaction mechanism. The Cr carbide may be formed by the reaction between Cr and C at elevated temperature, and the corresponding Gibbs free energy (unit: [J]) (T unit: [K]) could be described as follows [5,6]:…”
