SURFACE TREATMENT OF METALS, METHOD OF TESTING WITH RADIO-ACTIVE ISOTOPES

Abstract

An experimental technique is described for nondestructive testing of bond strength for aluminum metal surfaces bonded with organic adhesives. The new technique uses radioactive tracers (C(14)) in stearic acid to determine the amount of soil removed during cleaning operation. It also uses chromate ion (Cr(51)) in FPL solution, (sodium dichromate sulfuric acid), during the deoxidizing and etch treatment. The correlation between Cr(+6) sorbtion and bond strength was demonstrated as approximately linear.
