Fretting corrosion test fixture

A test fixture for fretting corrosion testing of first and second material specimens in a variable temperature environment, comprising in combination:

• clamping means;
• a flexure bar fixed at one end in said clamping means and formed to secure the first specimen intermediate the ends thereof;
• a load bar fixed at one end in said clamping means parallel to said flexure bar and formed to secure the second specimen near the other end thereof and in abutment with the first specimen;
• force exerting means connected to the other end of said flexure bar for producing a reciprocating force thereon in the plane formed by the respective longitudinal axes of said flexure and said load bars, said force exerting means including an adjustable means for maintaining a compressive load applied at the speciment interface during the application of said reciprocating force;
• and
• heating means enclosing said load bar and said flexure bar intermediate said clamping means and said force exerting means for increasing the environmental temperature about the first and second specimens.
