Abstract
The present invention relates to the use, as a hydraulic fluid or metalworking lubricant, of compositions having water as a base and yet possessing superior lubricating and wear preventing characteristics. The fluids of the invention comprise (1) a sulfurized molybdenum or antimony compound and (2) a phosphate ester or salt thereof. The compositions can be thickened, if desired, using for instance polyglycol, polyacrylic and polyvinyl alcohol-type thickeners. The use of corrosion inhibitors, metal deactivators and other adjuvants conventional in this art is also contemplated.
