A WATER-SOLUBLE POLYMER-BASED COMPOSITE LUBRICATING FILM

A solid lubricating film composed of a water-soluble cellulose derivat ion, acid phosphate, antiwear agent, corrosion inhibitor and moisture- resistant material, was studied for cold pressure working of ferrous m etal. The film adhered on the metal surface was examined by means of e lectronic probe microanalysis (EPMA), Auger electron spectroscopy (AES ), X-ray photoelectronic spectrum (XPS) before and after processing. A bout 6000 blocks (the shape shown in Table 1) were taken for actual ap plication experiments. Satisfactory results have been obtained.
