Surface engineering is a collective term for all technologies that can be used to change the properties of surfaces. This can be a coating, for example by galvanizing or painting, but also the removal of surface structures, for example by sandblasting, electropolishing or vibratory grinding. Which technology is used for surface processing always depends on the material of the workpiece or component - and, of course, on the function it will perform after the surface treatment.
Surface engineering can mechanically protect components against wear, friction and corrosion. Also, the electrical conductivity of a workpiece can be made possible or prevented by a surface treatment. Certain optical properties such as reflection or absorption of light waves can be achieved. And of course it is also possible to combine different surface treatments for the desired result.
