Electroplating and Thermal Coating

Contents:

The module follows on from the “Surface and Interface Engineering” module and expands on this with regard to industrially relevant coating processes. The focus here is on the topics of “Electroplating” and “Thermal Coating”.
Electroplating:
Relevant topics of wet-chemical coating processes are addressed and taught comprehensively.
Contents are
- Electrochemical fundamentals
- Modelling of electrochemical processes
- Fundamentals of electroplating
- Coating systems
- Coating processes
- Electrochemical analysis
- Coating characterization
Thermal coating:
The following thermal coating processes or coating process groups are considered in more detail:
- Thermal spraying
- Deposition welding
- CVD process
- PVD process

For these coating processes, the environmental relationships of the coating process and cross-process issues relating to the selection methodology for coatings are dealt with.
As both galvanic and thermal coatings are primarily used in tribological and/or chemical applications, the fundamentals of wear and corrosion are dealt with on the basis of corresponding applications. The potential for wear and corrosion protection on the coating side is derived and presented. However, surface coatings can also be used to specifically change a number of other properties (electrical and thermal conductivity, physical behavior, color, gloss, etc.), which is why these properties are also discussed in the course of this module. 

Qualification goals:

Electroplating:
Students master the essential processes of pre- and post-treatment as well as layer formation. This enables them to select coating systems for specific applications and to optimize processes.
Thermal coating:
Students are familiar with various groups of thermal coating processes that are specifically relevant to industry. They are able to correlate possible coating and substrate materials, coating formation and adhesion mechanisms and the resulting coating properties with the applicable coating processes and thus make a process and material selection for a possible thermal coating process based on the requirements profile for technical surfaces.
