Most engineers that have day-to-day interactions with lubricants are mechanically trained. Whether from a trade background as a fitter, turner or mechanic, or possibly an engineer from a mechanical, manufacturing or mechatronic discipline. Unfortunately, lubricants require a decent amount of chemistry knowledge. Lubricants ARE chemistry. So in this short course, we’ll try to run through a refresher of all the high school chemistry that you need to know in order to understand some of the key aspects of lubrication.
