Objective

The student can describe the anti-corrosive painting process. He or she is able to recognize impurities on steel surfaces and can select the right cleaning methods for them. He or she can explain the protection mechanisms of anti-corrosive paints and select proper pre-treatment methods, paint systems and application methods of paints. The student can describe the quality control specifications for surface treatment and carry out inspections needed in quality control. He or she can present the occupational and environmental safety requirements in anticorrosive painting. The student can calculate a tender for an anti-corrosive painting contract and can present the bidding process.
The student is able to describe the components and phenomenon of paints and adhesives that determines their performance and apply this knowledge to tasks related to painting and adhesive bonding.
The student can describe the corrosion prevention principles and coating processes of hot-dip coatings. The student knows the effects of dipping time, temperature and different pre-treatments on the coating properties. He or she knows the effects of steel composition on the coating, its microstructure and properties. In addition, he or she is able to take into consideration the structural design of steel components for successful galvanizing. The student knows the mechanical, corrosion and paintability properties of hot dip coated surfaces.
