Technologies of Surface Engineering
Contact
The lecture deals with the technical meaning of surfaces for the function of components in mechanical engineering. It will discuss the definition of the term surface and its characteristics and examinehe importance of the technical surface as an economically determining factor. Students learn to attach an adequate amount of importance to the respective application for future engineering functions of the technical surface, as is already the case for the volume function of a material. The lecture furthermore aims at explaining technologies that influence surface properties. In addition to thermal spraying processes, physical vapor deposition (PVD) and chemical vapor deposition (CVD) processes as well as deposition brazing and deposition welding, the class will also cover further surface technology processes. Starting from general and current application areas, material solutions and process solutions for the production of effective surface properties are presented and discussed. The focus is on wear and corrosion protection as well as protection against high temperature corrosion and oxidation, and protection against thermal stress. A further chapter will present the use of modeling and simulation in surface technology. During the exercises, students can deepen their knowledge regarding different surface technologies.
