ASTM F 1659 : 1995

CONTAINED IN VOL. 13.01, 2001 Specifies procedure for the performance of calcium phosphate ceramic coatings in shear and bending fatigue modes. This method, in the shear fatigue mode, evaluates the adhesive and cohesive properties of the coating on a metallic substrate, and in the bending fatigue mode evaluates the adhesion of the coating as well as the effects that the coating may have on the substrate material.

1.1 This test method covers the procedure for the performance of calcium phosphate ceramic coatings in shear and bending fatigue modes. In the shear fatigue mode this test method evaluates the adhesive and cohesive properties of the coating on a metallic substrate. In the bending fatigue mode, this test method evaluates both the adhesion of the coating as well as the effects that the coating may have on the substrate material. These test methods are limited to testing in air at ambient temperature. These test methods are not intended for application in fatigue tests of components or devices; however, the test method that most closely replicates the actual loading configuration is preferred.

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
