Materials and Surface Engineering is arguably the most important engineering discipline today. Starting from the study of structure, composition and properties of materials it covers the manufacturing and processes details. Surface Engineering has emerged in recent years as the avant-garde of Materials Technology, whereby expensive materials with adequate mechanical, chemical and thermal properties are deposited on he surface of regular substrates in order to achieve what is called as surface engineered materials. These are cost effective, long life and in some cases only options available for a severe and demanding application. Special applications range from aeronautical, chemical and textile industry to space and defense industry.
