Motivation

Additive Manufacturing Processes enable the realization of components with complex geometries using new material combinations. In addition to the mere fulfilment of structural-mechanical tasks, these components will have to offer additional functional properties to an increasing extent in the future. The surface quality, which is closely linked to the respective additive manufacturing process, often limits their possible applications. Restrictions can arise directly from the microstructure and the chemical and physical properties of the material combinations used.

Objectives

The PhD project pursues the approach of developing a novel ALD (Atomic Layer Deposition) process, which enables a tailored surface functionalization of additively manufactured components. The objective is a flexible process which allows to cover the different processes and material classes used in generative manufacturing. The coatings must show a high conformity and be able to functionalize (accessible) inner surfaces equally by penetrating the ALD precursors into complex geometries. Here metals, oxides or nitrides are to be applied in the form of individual thin layers as well as structures from several layers.
