Abstract
A hose and a method of producing the same. The hose includes a tubular resin inner layer, a metal plating layer formed on an outer peripheral surface of the resin inner layer, and a resin outer layer formed on an outer peripheral surface of the metal plating layer, wherein a chromium oxide film is formed on the outer peripheral surface of the resin inner layer and a metal film is formed on an outer peripheral surface of the chromium oxide film between the resin inner layer and the metal plating layer and the metal plating layer is formed on an outer peripheral surface of the metal film. Further, a chromium oxide film is formed between the metal plating layer and the resin outer layer.
Claims3
A hose comprising a tubular resin inner layer, a metal plating layer formed on an outer peripheral surface of the resin inner layer, and a resin outer layer formed on an outer peripheral surface of the metal plating layer, wherein a multilayered film comprising a chromium oxide film and a metal film is formed between the resin inner layer and the metal plating layer, the chromium oxide film of the multilayered film is positioned on the outer peripheral surface of the resin inner layer, the metal plating layer is positioned on an outer peripheral surface of the metal film in the multilayered film, a single-layer film of a chromium oxide film or a multilayered film comprising the chromium oxide film is formed between the metal plating layer and the resin outer layer, and the resin outer layer is positioned on an outer peripheral surface of the chromium oxide film in the multilayered film.
