Aims
On completion of this TLP you should:
- understand that surfaces that feel smooth to the touch and look smooth to the naked eye actually are not on a fine scale
- appreciate that two nominally flat surfaces are only in contact at certain points ("asperities")
- gain a more in-depth knowledge of friction and why it occurs
- know about different types of lubricant and why lubrication affects friction
- be aware of different types of wear processes
