COURSE DESCRIPTION

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.

Grading and evaluating student work in class and at the final exam

A student can pass a part or the entire exam by taking two partial tests during the semester. Students who do not pass the partial exams have to take an exam in the regular examination term. During the examination terms students take written and oral exam.
Scoring: <55% insufficient;55-66% sufficient (2); 67-78% good (3); 79-90% very good (4); 91-100% excellent (5)

Quality assurance methods that ensure the acquisition of exit competences

Keeping records of student attendance; annual analysis of the exam results; student survey in order to evaluate teachers, self–evaluation of teachers, feedback from students who have already graduated to relevance of curriculum.
