This report is an evaluation of various parameters in the phosphate- fluoride treatment stabilized for surface prep- aration of titanium preparatory to adhesive bonding. The process was compared to the standard phosphate-fluoride treat-ment. The stabilized process was found to provide an improvement in the durability of adhesive- bonded joints exposed to moisture and stress. This process was developed by R.F. Wegman at Picatinny Arsenal.
