Coatings for spinning applications and rings and travelers coated therewith

An improved ring and traveler system having high wear resistance and low friction characteristics for use in textile applications requiring winding of yarn onto rotating spindles, said ring defining at least one flange for receiving said traveler, said traveler having an intermediate portion and inturned horns defining a gap therebetween for sliding around said flange, said ring being fixedly mounted to a ring rail and concentrically disposed about a rotating spindle having a bobbin mounted thereon for reciprocating vertically thereabout, said applications further having yarn fed from drafting rolls for threading through said traveler and winding onto said bobbin for tensioning and guiding said yarn onto said bobbin, the improvement comprising:

• a coating on the surface of said traveler and said ring, said traveler being constructed of a first metal and said ring being constructed of a second metal wherein said first and second metals are capable of undergoing a replacement reaction, said coating comprising copper selenide chemically deposited on said traveler and said ring by a replacement reaction between copper and said respective first and second metals.
