Fretting Corrosion Test Fixture
Abstract
The patent application describes a fretting corrosion test fixture, for evaluating materials or coatings in variable temperature environments, having a load bar and a flexure bar rigidly mounted at their respective one ends in the jaws of a vise and separated by a shim of selected thickness. The load and flexure bars are cantilevered out from the vise, the other end of the flexure bar being connected to an eccentric drive assembly for deflecting the flexure bar. A pair of material specimens having a combined thickness equal to that of the shim are attached, respectively, near the end of the load bar and intermediate the ends of the flexure bar and in contact with each other. A cylindrical furnace is mounted for enclosing the specimens for high temperature evaluation. Fretting corrosion is produced on the attached fretting specimens under controlled conditions by deflecting the flexure bar a predetermined amount resulting in relative movement and load at the interface of the specimens.
