Unit Description and General Aims

The objective in presenting this unit is to provide students with a thorough overview of Tribology fundamentals, comprehension of the key lubricant properties and types, and the knowledge to select the right lubricant for a particular application. The emphasis is on enabling students to get the most up-to-date information on lubrication related issues and best practices.

Students will also be instructed on the many aspects of maintenance, the latest maintenance techniques and technologies, be equipped with the skills to perform condition monitoring tasks and to recognize and solve precision maintenance issues in a structured manner towards improved reliability and performance.

The subject matter covered in this unit will include the fundamental Tribology concepts; lubricant and additive properties; the identification of the different lubricant types; lubricant storage and stability; preventive and predictive maintenance strategies; condition monitoring tasks; and, precision maintenance programs. Students will also undertake project work involving a sample preventive maintenance strategy for a given application and carry out failure analysis for a given equipment/system.

Detailed knowledge of Tribology concepts and lubricants is key to effective and efficient maintenance. Many operational problems can be traced to inadequate knowledge of lubricants, lack of basic maintenance, and poor asset management skills. It is through the detailed knowledge of Tribology concepts, lubricants, and timely implementation of maintenance practices, that failures can be averted and/or their symptoms can be accurately identified, and corrective measures initiated well in time to prevent unscheduled and sometimes even catastrophic failures. At the conclusion of this unit, students will have been imparted with the requisite knowledge of lubricants and maintenance issues to appreciate this and ensure that effective products and effective maintenance strategies, plans, and programs are utilised, established, and perpetually sustained.
