have been included in lubricants for cold rolling of aluminium. They are organic compounds which contain a functional polar group e.g. acids,alcohols,esters. The presence of these polar groups causes the molecules to be attracted and adsorbed onto the metal surfaces. When a -component additive is dissolved in the base oil,there

Choosing a Metal-Forming Lubricant

Choosing a Metal-Forming Lubricant. Synthetics can be emulsified with water (sometimes known as neo-synthetics) to offer better lubricity. Solid (or dry) film lubrication is the use of solid materials (such as graphite) in conjunction with or without oil or water. The best applications are in extreme conditions such as low shaft speeds, high and low temperatures, and high pressures.

Friction and Lubrication - ASM International

Boundary lubrication is the most widely encoun-tered lubrication condition in metal forming. Mixed-layer lubrication (Fig. 7.2) is also fre-quently encountered in sheet metal forming. In this case, the micropeaks of the metal surface experience boundary lubrication conditions and the microvalleys of the metal surface become filled with the lubricant.
