Abstract:
Lecture 1: Introduction to Tribology
- Definition, history, and
significance - Early civilizations’ friction
reduction methods (e.g., rollers, wheels, bearings) - Middle Ages to Industrial
Revolution: bearing material evolution - 20th Century: oil additives,
analytical tools (SEM, AFM, XPS) - Recent advances: nanotribology,
bio-tribology, biodegradable lubricants, quantum levitation

Bio:
Dr. Lorne Floyd Brock CLS – Over 40 years in Industrial Lubrication
Lorne, in retirement, is President and technical advisor for ENROL Inc., a consulting company that provides lubrication solutions, sales support and training for clients worldwide (North and South America, China, India, and Europe).
Before Enrol Inc, Lorne Brock spent 34 years in lubrication R&D, marketing and lubricant application, beginning in 1978 as an R&D chemist with Imperial Oil and Paramins (Infineum) and a member of the ExxonMobil organization until his retirement when he was Global Product Technical Advisor for Application and Development of Industrial Lubricants, synthetic EP fluids and greases with responsibility for the resource industries (Mining, Pulp and Paper, Power Generation, Steel and Cement.)
He has lectured on Tribology and Lubrication practices at the University of Toronto, University of Wisconsin Madison, University of Edinburgh; Engineering, Tsinghua University Beijing, Mechanical Engineering and the Indian Institute of Technology, Delhi.
Dr. George Staniewski, P.Eng., CLS, OMA I&II, has combined academic (11 years) and industrial (37 years) experience in the field of Tribology. He has been internationally recognized as a Fellow of the Society of Tribology and Lubrication Engineers (STLE member since 1982) for his work on phosphate ester fire-resistant fluids in EHC systems. He has been a member of STLE since 1982 and held several positions on national and international committees (Power Generation and OMA and CLS Certification).
George was the leading expert in the field of Tribology at Ontario Hydro/OPG, responsible for providing technical support to the Engineering, Operations and Maintenance departments. He was also the OPG subject matter expert on mechanical seals, plain and rolling element bearings, lubricant degradation, lubrication fundamentals and the corporate Predictive Maintenance program coordinator.
He also gave several presentations on lubrication to the INPO, NMAC, STLE, ASTM, and EPRI, along with authoring several OPG standards, specifications, and instructions. George has chaired several OPG lubrications and PdM self-assessments.
