2. Bag-plateau or mixed diet: physico-chemical aspects
2.1 Additives and "metal" surface reactivity
2.1.1 Modes of action and nature of additives
Experience shows that the addition of small quantities of certain chemical compounds to lubricants, known as lubricant additives, reduces friction and wear rates. Their action is chemical, and is therefore highly specific to the chemical composition of the bodies involved, depending mainly on the concentration c of the additive in the lubricant and the temperature θ. There are two main types of additive action (figure...
