Measurement and Evaluation of Surfaces By Evaporative Rate Analysis III Quality of Seal on Anodized Aluminum 660373

First studies of the quality of seal of anodized aluminum through measurement and evaluation of the surface by evaporative rate analysis of an added test solution showed a generally orderly response; that is, the greater the extent of seal, the more rapid the evaporation of the test material. However, more detailed studies have shown some marked anomalies in evaporative response; quantitative data are presented herein for the first time.
The evidence presented indicates that even modest high humidity aging of nonboil sealed surfaces is superior to any boil sealing insofar as desorptive phenomena are concerned.
