摘要： A METHOD FOR IMPROVING THE ADHESIVE BOND BETWEEN AN ALUMINUM SURFACE AND OTHER MATERIALS COMPRISING PRETREATING THE ALUMINUM SURFACE BY ANODIZING IN AN ACIDIC ELECTROLYTE IN SUCH AS MANNER THAT AN INITIALLY FORMED ANODIC OXIDE LAYER DISSOLVES AT ABOUT THE SAME RATE AT WHICH IT IS BEING FORMED AND PSEUDOBOEHMITE IS FORMED IN THE OXIDE COATING THAT REMAINS ON THE ALUMINUM SURFACE.

摘要： Aluminized steel strip is anodized during movement through a succession of anodizing tanks, each housing at least one anodizing stage. The strip is subjected to successively higher current densities in successive anodizing stages. The current density in the first anodizing stage is controlled to prevent pitting, and the increase in current density from one anodizing stage to the next is relatively large.

摘要： In procedure for producing colored coatings on aluminum by first anodizing the aluminum surface and then treating such anodically coated surface with alternating current in an acidic bath containing Ni or Co ions to produce a colored deposit in the coating, simplified control with effective coloring results is achieved by providing a content of combined aluminum in the acidic bath while maintaining the bath at a pH, notably about 5 to about 6, which restricts the dissolved A1 ion concentration to a low value.

摘要： A RADIATION RESISTANT CHROMIUM ACTIVATED ALUMINUM OXIDE SCINTILLATOR PRODUCED BY IMMERSING AN ALUMINUM ANODE AND LEAD CATHODE IN AN ANODIC BATH AND GRADUALLY INCREASING AN APPLIED POTENTIAL UNTIL BRIGHT FLASHES OR "ANODIC SCINTILLATION" OCCURS WHEREBY CR IONS FROM THE SOLUTION ARE INJECTED INTO HE AL2O3 BASE LATTICE. THE SCINTILLATORS PRODUCED BY THIS PROCESS MAY BE READILY UTILIZED TO VISUALLY AID IN THE CONTROL AND TRANSPORT OF HIGH INTENSITY BEAMS WITHOUT RADIATION DAMAGE THERETO.
