Publicerad: 15 januari 2020

COURSE SYLLABUS, third-cycle courses
Sista ansökningsdatum 14 februari 2020

Entry requirements: Basic knowledge in tribology (especially lubrication regime) and well trained scientific method (stepwise and logical algorithm).

Course content: 
(1) Introduction: Definition of tribo-chemistry and mechano-chemistry, terminology in chemistry and lubrication engineering, key references, tips for online database.
(2) Description of chemistry: elements, chemical formula, chemical structure, chemical bonds, isomers and allotrope, electron transfer in chemical reactions.     
(3) Friction modifiers (FM): Typical molecular structure and the role, kinetics of the boundary film formation, physical and chemical interactions between substances.   
(4) Anti-wear agents (AW): Typical molecular structure and the role of active elements, driving forces for the reaction, stability of boundary film against rubbing. 
(5) Extreme pressure additives (EP): Typical molecular structure and active elements, the importance of controlled wear to prevent failure, engineering trade-off. 
(6) Solid lubricants and coatings: Chemical/physical properties and role, similarity and dissimilarity to FM/AW, technical challenges in comparison with FM/AW/EP.   
(7) Antioxidants (AO): Different types of antioxidants and roles, radical chain reaction mechanism, reactions under EHL, ageing and monitoring for maintenance.
(8) Tools for mechanistic investigations: Instrumental analysis of rubbed surfaces, the importance of chemical and spatial resolutions, link to the mechanical properties, in situ and in lubro analyses, in silico study the importance of complemental analysis.

Learning outcomes: Demonstrate broad knowledge and systematic understanding of the research field as well as advanced and up-to-date specialized knowledge in a limited area of this field, and demonstrate familiarity with research methodology in general and the methods of the specific field of research in particular.

Course methods: Lectures and exercise in literature survey (Students use their own laptop computer).

Examination form: Home assignment (80%) and final report (20%, deadline is 9 April 2020).

Grading scale: Pass/Fail

Course literature: Each attendee will receive handouts as pdf, by e-mail

Education cycle: LP3-4, VT20 

Course is given periodically: This is a part of serial course on “Topics in tribology”. The next program will be “sustainable development goals with tribology” during autumn in 2020. 

Deadline for application:  2020-02-14
