Abstract:
Herein disclosed is a dry type continuous wire drawing process which can retain satisfactory working circumstances while eliminating the problem of disposal of waste liquids. The wire drawing process includes the steps of descaling a wire to be drawn, coating the descaled wire with a lubricant, and drawing the lubricant-coated wire through a drawing die. The descaling step is conducted in a mechanical manner. At the lubricant coating step, the descaled wire is once coated with lime powder and then with metallic soap powder. Thus. the three steps recited are conducted under dry and continuous conditions. At the lubricant coating step, the lime-coated wire may be coated with powder of sodium stearate before it is coated with the metallic soap.

Abstract:
PROBLEM TO BE SOLVED: To provide dry film lubricant coatings by using a silicone resin binder, either as an aqueous emulsion or in a solvent-based system, to fix an alkaline earth metal fluoride to a substrate.SOLUTION: The compositions used to apply the coatings may also include relatively minor amounts of xylene, ammonium benzoate, a wetting agent, and/or a porosity-inducing agent, although none of those additives remains in the cured coating. Multi-layer dry film lubricant coatings are also disclosed, with the multi-layer coating having a basecoat layer as described above, and a topcoat layer made of a layer-lattice solid such as graphite or molybdenum disulfide, and a silicone resin, aluminum phosphate or an alkali metal silicate binder.

PCT No. PCT/DE96/00344 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed Feb. 23, 1996 PCT Pub. No. WO96/26793 PCT Pub. Date Sep. 6, 1996In accordance with the method according to the invention, for the production of the plastics overlay, first of all a paste is made of a plastics dispersion and fillers. This paste is free of organic solvents and is applied to a sintered porous metal layer. The multilayer material thus produced is then sintered. Since the use of organic solvents is dispensed with, health risks and the risk of fire are reduced. Moreover, the composite materials produced according to the invention exhibit excellent cavitation resistance. In addition to conventional lubricant-free applications, such as bearings, these composite materials may consequently be used in particular in gear pumps and shock absorbers.
