Università Roma Tre

Understanding material characterization methods
- X-ray diffraction, electron microscopy (SEM-TEM) and Energy Dispersive Spectroscopy (EDS), micro- and nano-mechanical testing techniques. Notes on metallography and non-destructive testing.
Wet Corrosion
- Electrochemical aspects of degradation, wet corrosion, Pourbaix diagrams, corrosion kinetics, ddp and mixed potential theory - passive, corrosion in natural environments and hostile environments, prevention, protection, diagnosis and monitoring methods

Tribology
- Contact mechanics. Tribological aspects of degradation (adhesion, friction and wear), main types of wear (adhesive and abrasive).
- Theory, methods and standards for quantifying wear, protection strategies.
Protection of materials
- wear-resistant and corrosion-resistant coatings, thermal barrier coatings (TBCs).
- Deposition technologies: galvanic coatings, Physical vapour Deposition (PVD) and Chemical Vapour Deposition coatings, thermal spray.

Composite materials
- basic concepts (matrix-reinforcement-interface) and classification; rule of mixture, matrix reinforcement, durability and degradation (creep, fatigue, hydrolysis). Design criteria: laminated and sandwich composite structures; Production technologies: hand layup, Filament winding, hot stamping, vacuum bag, Resin Transfer Molding, Spray-up. Examples of applications of composites.

Advanced ceramics
- correlation between precursors, production, structure and properties of ceramics. Reliability criteria (Weibull statistics); Production technologies: sintering, hot isostatic pressing, slip casting, tape casting, co-deposition, thermal spraying. Examples of application of ceramics for refractory components and thermal barrier coatings. Wear and corrosion.
Material Selection Processes:
Materials Selection Processes using CES (Cambridge Engineering Selector) software: basic concepts, performance indices and their graphical representation, material selection problems in a number of relevant examples for mechanical and aeronautical engineering.
