Students acquire basic theoretical and practical knowledge in the field of tribology and tribological systems, theory of lubrication, wear and damage of the surfaces, anti friction materials, lubricants, motor oils, and other fluids as well as reliability theory and its application in machine exploitation and maintenance

Students are capable of routinely using the acquired knowledge and skills working independently or in teams, as well as the ability of further advancement in the complex area of machine usage.

Fundamentals of tribology. Notion and definitions of tribology and tribological systems. Characteristics of tribological surface: structure, geometry and shape of tribological surface, relation of tribological surfaces in contact. Friction. Theories of lubrication: boundary, total and mixed lubrication. Wear and damage of the surfaces: definition and classification. Mechanical wear: adhesive wear, abrasive wear, flow erosion, fatigue wear, electrical erosion. Other forms of wear and damage of material surface: chemical, thermal and biological wear. Light metals and anti friction alloys. Lubrication oils and grease: composition, physical and chemical properties, diagnostics and exchange criteria, classification and specifications according to rheology and operation properties. Organization of lubrication service and its tasks. Storage and distribution of lubricants. Lubricant handling. Waste lubricants and their treatment. Motor oils and other engine fluids. Reliability and application of reliability in machine exploitation and maintenance.

Oral presentation of the material accompanied with the use of suitable illustrations, schemes and diagrams. Auditory practice is related calculations and examples and laboratory practice is conducted using suitable laboratory equipment in the laboratory or service and repair workshops
