Prevention of cathodic delamination of polyurethane adhesive from Ti-A16-4V alloy using fluorinated primers

摘要

The fluorosilane and FEP films greatly outperform TEOS and control films in preventing the CDL of polyure-thane adhesive from grit blasted titanium alloy. Priming grit blasted titanium alloy with cured (heptadecafluoro-1,1,2,2-tetrahydrodecyl) trimethoxysilane slows the CDL rate by an order of magnitude compared to a primerless control.
