Interface strength and degradation of adhesively bonded porous aluminum oxides

Surface coating: interface strength and degradation Chromic acid anodizing has been the dominant electrochemical process used to create a thin aluminum oxide layer upon aluminum alloys. Such thin layers are critical to the corrosion protection of alloys that enable many of our daily expectations, in...
