Tribology is of fundamental importance to the design of all products and machinery that involve motion, and is all about friction, wear and lubrication. In practice, these translate into lifetime performance, reliability, energy efficiency, maintenance and often basic functionality. Tribology is ubiquitous; for example, in products that interact with the human body, tribology also plays a large part in determining comfort and discomfort, “feel” perception and damage to tissue.

Tribological behaviour, especially when considered as a function of time, is elusive and not easy to predict. Friction and wear are predominantly surface phenomena and are affected by many factors including the materials, forces, roughness and environment involved and, moreover, these factors often interact with each other. Unfortunately, this means that questions such as “What is the friction coefficient of steel?” and “What is the wear rate of aluminium?” cannot be answered in a simple way. Nevertheless, a basic understanding of how different factors can influence friction and wear behaviour can help greatly in designing the parts of products and machines where tribology phenomena are active.

In this talk, I will give an overview of how tribological behaviour can be influenced in design, what factors should be taken into account and why, and illustrate this using practical design examples.
