Abstract
Official abstract text for this publication.
A coating system for an aluminum component includes a substrate formed from an aluminum material, a zinc or zinc alloy sacrificial layer deposited on the substrate, and an aluminum coating deposited over the zinc or zinc alloy sacrificial layer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A coating system for an aluminum component which comprises: a substrate formed from an aluminum material; a zinc material sacrificial layer deposited on said substrate; and an aluminum coating deposited over said zinc sacrificial layer. 2 . The coating system of claim 1 , wherein said sacrificial layer is zinc. 3 . The coating system of claim 1 , wherein said sacrificial layer is a zinc alloy. 4 . The coating system of claim 1 , wherein said sacrificial layer has a thickness of less than 10 microns and said aluminum coating has a thickness in the range of from 5 microns to 50 microns. 5 . The coating system of claim 1 , wherein said substrate is an aluminum alloy. 6 . The coating system of claim 1 , wherein said aluminum coating is pure aluminum. 7 . The coating system of claim 1 , wherein said aluminum coating is an electroplated aluminum coating. 8 . The coating system of claim 1 , wherein said substrate is a turbine engine component. 9 . The coating system of claim 1 , wherein said substrate is a fan blade used in a turbine engine. 10 . A method for forming a coating system which enhances resistance against corrosion comprising the steps of: providing a substrate formed from an aluminum material; forming a zinc material underlayer on a surface of said substrate; and forming an aluminum coating on said zinc material underlayer. 11 . The method of claim 10 , wherein said underlayer forming step comprises depositing a zinc or zinc alloy on said surface using at least one zincating process. 12 . The method of claim 11 , further comprising plating zinc or a zinc alloy onto said deposited zinc or zinc alloy. 13 . The method of claim 10 , wherein said aluminum coating forming step comprises depositing aluminum or an aluminum alloy onto said underlayer. 14 . The method of claim 10 , wherein said aluminum coating forming step comprises electroplating aluminum onto said underlayer.
