Appl. No.:

09/493907

Inventors:

Guido M. Campagna - Farmington Hills MI
James D. McDaniel - Ortonville MI

Assignee:

ITT Automotive, Inc. - Auburn Hills MI

International Classification:

B29D 2200

US Classification:

428 3691, 428 358, 428 359, 428192, 138143, 138146

Abstract:

A method for preparing a multi-layer tube, useful prior to endforming for brakeline connections, comprises the steps of forming a metal tube having an outer surface and an end and bonding a corrosion resistant layer to the metal tube outer surface. A surface treatment layer is bonded to the corrosion resistant layer. A first polymeric layer is extruded onto the metal tube, such that is bonds to the surface treatment layer; and a second polymeric layer is extruded onto the metal tube, such that it bonds to the first polymeric layer. The method further comprises the step of vaporizing and removing at least a portion of the first and second polymeric layers from an area adjacent the end by rotating an axially defocused, generally elliptical cross-sectionally shaped laser beam 360Â about the area, while leaving the corrosion resistant layer intact.

Abstract:

A corrosion resistant multi-layer tube comprises a metal tube; a zinc layer bonded to the metal tube outer surface; a surface treatment layer bonded to the zinc layer; a priming layer; a first polymeric layer bonded to the priming layer; a second polymeric layer bonded to the first polymeric layer. A process for manufacturing the tube comprises the step of extruding multiple layers of a melt-processible thermoplastic to a pretreated metal tube having an external surface with at least a zinc based coating, a sealant coating on top of the zinc based coating, and a primer coating on top of the sealant coating. The primer coating is preferably applied by an airless spray system in a closed atmosphere, wherein substantially no volatile organic compounds escape into the atmosphere. The polymeric layer(s) remain adhered to the metal tube, even when exposed for prolonged periods to aggressively corrosive environments.

Abstract:

A multi-layer tube having a metal tube having an outer surface and a zinc layer bonded to the metal tube outer surface. The zinc layer being selected from the group consisting of zinc plating, zinc nickel alloys, zinc cobalt alloys, zinc aluminum alloys, and mixtures thereof. A surface treatment layer is bonded to the zinc layer, wherein the surface treatment layer is selected from the group consisting of a zinc/aluminum/rare earth alloy, phosphate, chromate and mixtures thereof. A first polymeric layer is bonded to the surface treatment layer, wherein the first polymeric layer is selected from the group consisting of a thermoplastic elastomer, an ionomer, a nylon, a fluoropolymer, and mixtures thereof. A second polymeric layer is bonded to the first polymeric layer, wherein the second polymeric layer is selected from the group consisting of a nylon, a thermoplastic elastomer, a fluoropolymer, and mixtures thereof. The tube also has a continuous interior layer made of non-reactive material which is preferably made of a polymeric material which is substantially non-reactive in the presence of short chain alcohols.
