Surface: Functions and Properties

This lecture explores the functions and properties associated with surfaces, covering topics such as heat dissipation, roughness, porosity, thermal contact, energy dissipation, adhesive properties, and surface treatments. It delves into the translation of vague requirements into physical specifications, essential physical properties of surfaces, and common surface metrics. The importance of surface roughness on mechanical properties is discussed, along with surface treatments like coatings, conversion methods, and thermo-chemical processes. Optical properties, optical scattering, and the influence of surface smoothness on light reflection are also examined.
