Since the 1980s, the pace of technology innovations has accelerated exponentially. The advent of high efficiency yet environmental friendly diesel engine technology, micro-electro-mechanical devices (MEMs), better and more durable biomaterials, and ever increasing data storage technology make performance demands on mechanical systems at an unprecedented level. Tribology has again become the bottleneck in many of these technologies.In diesel technology, a million mile durability without an engine overhaul is the current OEM goal. To reach this goal, materials and lubrication technologies have been reexamined to see what is feasible. Is it possible to achieve lubrication for life for some of the engine components? What are the barriers that prevent this from happening? In MEMs, current design and practice avoid the use of moving parts as much as possible. But if the friction and durability requirements (billions of cycles) can be solved, the potential of MEMs could increase hundred folds. Human joint replacement currently has 10 to 15 years life, yet because of longer life span we enjoy, a 30 years joint replacement technology is needed. In all these examples, the control of friction and wear over a long period of time is the central issue.High performance tribosystems today require the following characteristics: life-time constant/predictable level of friction and wear; long durability; cost effective design; robust design; easy and low cost maintenance or lubricated for life.
