| The goal | The aim of this course is to introduce students to all phases in the deposition of metal coating, the mechanism of deposition, as well as the functions of metallic coatings. The student should master the technology of deposition of different metallic coatings and protection by metallic coatings and to learn the differences of protection by applying metallic and/or non-metallic coatings. | |||
| The outcome | Student has acquired basic theoretical knowledge of the types of metallic coatings, the methods of deposition and properties of metallic coatings. Student learnt what type of plating solution to use for a particular metallic coating, depending on the application of a particular coated object. Student is able to apply basic calculations in electrodeposition, as well as different experimental methods of metal coatings deposition, depending on their shape, size and properties. | |||
