Provided are metallic sulfide coated travelers, particularly tungsten disulfide coated travelers, methods of forming metallic sulfide coated travelers, and systems for use of metallic sulfide coated travelers. The metallic sulfide coating results in reduced yarn loading on the coated travelers, reduced heat generation during the spinning operation, and reduced wear of the traveler.

The present invention relates to a method for producing an electrical contact, in particular an electrical plug contact, comprising the steps of a) providing a substrate, wherein the substrate has a metallic and/or metallized surface, and b) applying a low-friction surface to the metallic and/or metallized surface of the substrate, wherein the low-friction surface is applied by mechanical rubbing, polishing and/or buffing of a solid lubricant; or wherein the low-friction surface is applied by spray application of a solid lubricant; or wherein the low-friction surface is applied by applying a solid lubricant by means of a drum washer; and wherein the low-friction surface (6) has a film thickness of 0.001 ?m-4 ?m.

A method is disclosed for manufacturing a blade tip coating. The blade tip coating (152) comprising an abrasive (156) and a matrix (154). The method comprises forming a mixture comprising the abrasive, a precursor of the matrix, and an additional particulate (158). The mixture is pressed, the additional particulate acting as a stop to limit thickness reduction of the mixture.

The present application describes the development of a method for creating a continuous conductive metal layer on a surface of a component, the component preferably made of molded acrylonitrile butadiene styrene polymer (ABS) or polycarbonate/ABS (PC/ABS) blend, the method utilizing cold sintering. This method avoids the need for chromic acid etching pretreatment prior to the electroplating process. Continuous, conductive and thickness-controllable layers of metals such as Ni, Fe, Cu or Ni/Fe have been created on the plastic surface using the cold sintering. The method will also work with any other metal. Thus, molded ABS or PC/ABS parts can be further electroplated without the need to go through the undesirable etching process.

A method of compacting an anti-corrosive paint comprising metal particles and covering a mechanical part such as a turbine engine part, the method comprising a step of at least one spraying of solid ice particles on the part so as to densify and to make the paint electrically conductive.
