EM 562 - Surface Engineering ( Engenharia das superfícies ) Physical and chemical characterization of technical surfaces. Surface analysis and observation. Surface metrology; normalized parameters, limitations and applications. Real contact area and contact stresses. Friction; sliding friction and rolling friction. Life of mechanical parts – wear processes; adhesion, abrasion, erosion, surface fatigue and contact corrosion. Physical and mathematical models, most important parameters and ways to fight each wear mode. Materials for contacts. Coatings and surface treatments; most important characteristics and selection criteria. Organic coatings and polymers, enamels, metallic and ceramic coatings. Thermal and mechanical treatments. Objectives To sensitise the students for the importance of technical surfaces in the function, durability and liability of the equipments used everyday. To transmit, in a systematic way, the more important knowledge related to surface degradation by wear processes, as well as the ways to minimise in each case, the negative consequences of such phenomena. To endow the students with the information allowing selecting the more appropriate surface finish and/or surface treatment for a given application. To develop experimental, analysis and observation ability in the students, and in parallel, to confront them with the necessity of exposing, in writing and orally, the results of their works. <<<<<<<<<<  BACK  <<<<<<<<<<
