Abstract:

Titanium is used in industry to manufacture many consumer products such as softball bats and golf clubs. It is also widely used in aerospace and the defense industries. At issue is that titanium does not maintain a good adhesive bond with organic coating systems. This study evaluates the adhesion of two nonchromate DoD primer, MIL-P-53022 and MIL-PRF-23377 Class N, relative to a direct to metal process using no primer. The evaluation method was based on ASTM D 4541 and used standard hydraulic adhesion testing equipment testing. The effectiveness of each method is then discussed with respect to strength values and failure modes.
