Learning outcomes
|
The aim of the course is to acquaint students with methods and procedures used in surface modification of materials. Emphasis will be put on the methodology of preparation of surface treatments, the actual formation of coatings and determination of parameters of coating technologies. The lectures will introduce the basic types of surface modifications, their application in engineering and basic financial and environmental aspects. The individual exercises will present the theoretical and practical aspects of the possibility of surface treatment of technical materials.
Graduates of the subject "Surface treatment" acquire professional knowledge during their studies, professional skills and general competences about basic types of surface modifications and various possibilities of their implementation. At the same time, they acquire information on theoretical and practical aspects (exercises, company visits) of the possibility of surface treatment of technical materials in order to ensure certain useful properties of the surface. The subject is designed so that the student during the course of the study, to demonstrate the ability to use the acquired expertise, professional skills and general competences gained from theoretical lectures and practical exercises.
