Abstract

An adhesively bonded article includes a metallic substrate that has an oxide layer thereon, a phosphonate bond promoter coating on the oxide layer, an adhesive material on the bond promoter coating, and a component bonded to the metallic substrate by way of the adhesive material.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An adhesively bonded article comprising:
 a metallic substrate having an oxide layer thereon;   a phosphonate bond promoter coating on the oxide layer;   an adhesive material on the bond promoter coating; and   a component bonded to the metallic substrate by way of the adhesive material.   
     
     
         2 . The adhesively bonded article as recited in  claim 1 , wherein the metallic substrate is an aluminum alloy. 
     
     
         3 . The adhesively bonded article as recited in  claim 1 , wherein the bond promoter coating is a monolayer. 
     
     
         4 . The adhesively bonded article as recited in  claim 1 , wherein the adhesive material is polymeric. 
     
     
         5 . The adhesively bonded article as recited in  claim 1 , wherein the adhesive material is epoxy. 
     
     
         6 . The adhesively bonded article as recited in  claim 1 , wherein the metallic substrate is an aluminum alloy and the oxide layer is aluminum oxide. 
     
     
         7 . The adhesively bonded article as recited in  claim 1 , wherein the component includes a honeycomb material. 
     
     
         8 . The adhesively bonded article as recited in  claim 1 , wherein the metallic substrate is a sheet. 
     
     
         9 . The adhesively bonded article as recited in  claim 1 , wherein the metallic substrate is an aluminum alloy sheet.
