Objectives
The course has the main objective of forming students in the most different variants of the surface modification technologies for improving wear and corrosion behaviour of materials.This course intends to supply the student with the ability to:
1 - Select the best procedure for surface modification in order to achieve the envisaged objectives considering not only technical problems but also processing costs.
2 - Achieve a basic Knowledge level about surface modification technologies which allow the students to easily access future detailed information about each one.
3 - Be motivated for new techniques with potential to be developed worldwide.
Learning outcomes
At the end of this module, students shall be able to:
- analyse and understand the main phenomena intervening on the degradation of materials, mainly those related with wear and corrosion
- understand the importance of the technologies of surface modification to avoid and control the problems created by the degradation of materials.
Skills outcomes
Analysis and synthesis
Knowledge of a foreign language
Use of internet as a communication via and information source
Critical reasoning
Ability to apply in practical situations the theory
Syllabus
1. Introduction and motivations - why surface modification; advantages and drawbacks of these technologies; economical aspects
2. Surface modification processes - with changes in the chemical composition; without changes in the chemical composition; coatings (by atomic deposition; by particles deposition; by diffusion; bulk coatings); selection of a coating technology; main steps in coatings deposition; main fields of coatings applications.
3. Global perspective in the surface treatments for tribological applications - mechanical; thermal; by surface melting; thermochemical (cementation, nitruration, and carbonitruration);ionic implantation; chemical treatments; welding; plasma spraying; CVD and PVD.
4. Sputtering - different sputtering modes; steps in the sputtering process; influence of deposition parameters on the coatings properties; reactive sputtering; residual stresses; adhesion.
5. Growing and deposition of coatings for tribological applications, nucleation /structure, chemical composition, morphology.
