Abstract

Nitriding and carburizing by laser irradiation in combination with a process gas is a common method to enhance the surface properties of various materials. This chapter discusses the different aspects of the process starting from fundamental mechanism up to engineering applicability. It will introduce and classify the method followed by a brief but detailed summary on the basic physical and chemical mechanisms involved. Further, the most common materials, their suitability ...
