Technology of Materials

By the end of this subject, students will be able to have: 1. a systematic understanding of the key aspects and concepts of surface engineering 2. coherent knowledge of surface engineering including some at the forefront of the branch in mechanical engineering; 3. awareness of the wider multidisciplinary context of engineering. 4. the ability to apply their knowledge and understanding to identify, formulate and solve problems of surface engineering using established methods; 5. an understanding of methodologies in corrosion and wear of surfaces and an ability to use them. 6. the ability to design and conduct appropriate experiments of corrosion and wear testing and coating of surfaces, interpret the data and draw conclusions. 7. workshop and laboratory skills in surface engineering. 8. demonstrate awareness of the health, safety and legal issues and responsibilities of engineering practice, the impact of engineering solutions in a societal and environmental context, and commit to professional ethics, responsibilities and norms of engineering practice;

During the lectures, the main concepts will be explained and the students will delve into them thorough short oral questions they should be reason out. During the fourteen weeks the lectures last, eight assessment exercises will be raised to the students to be individually solved with the aim of going more deeply into the contents taught during the lectures. Students should attend to two lab sessions, obtain the required experimental data and solve in small groups the raised questions. The lab session will have the following contents. -session 1: Corrosion -session 2: Coatings
