Abstract:
This invention relates to a structural coating comprising a polymeric resin, a borate-based additive, and a dynamic stabilization material. The borate-based additive provides corrosion protection through electrochemical binding of active surface corrosive sites, lubrication enhancement through the creation and re-supply to a surface where friction contact occasionally occurs of a weak slip lane crystalline material which may be a locally formed product utilizing local atmospheric humidity, and a material for reaction with an initiator to provide for freezing point depression during coating application. The dynamic stabilization material creates a balance of stabilized material for supply of corrosion protection product, lubrication reduction product, and freezing point depression product.

Dry film lubricant coatings are provided 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. 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.

Abstract:
According to the method of the invention, first a paste is produced from a plastics dispersion and fillers in order to form the plastics sliding layer. This paste is free from organic solvents and is applied to a sintered porous metal layer. The resultant multi-layer material is then sintered. Since organic solvents are not used, the risks to health and the risk of fire are considerably reduced. Furthermore, the composite materials produced according to the invention have exceptional resistance to cavitation. In addition to conventional fields of application relative to lubrication-free articles, such as bearings, these composite materials can therefore also be used in gear pumps and shock absorbers.
