Status of the course

Course objectives

Students will acquire knowledge that enables them to perform self-monitoring or
performing electroplating process. The knowledge acquired can also use to explore and improve the electrodeposition processes.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After successfully passing the exam, students will be able to:
1. Select the most appropriate metal coating for the corresponding metal surfaces.
2. Independently run or monitor the electroplating process.
3. Distinguish all process parameters that affect the quality of metal coatings.
4. Examine the quality of the obtained metallic coatings.
