ASTM F1147-05
(Test Method)Standard Test Method for Tension Testing of Calcium Phosphate and Metal Coatings
Standard Test Method for Tension Testing of Calcium Phosphate and Metal Coatings
SIGNIFICANCE AND USE
The tensile test method is recommended for tension testing of calcium phosphate/substrate or porous metal coating/substrate combinations and can provide information on the adhesive or cohesive strength of coatings under (uniaxial) tensile stress.
The test method may be useful for comparative evaluation of adhesive or cohesive strengths of a variety of types of coatings. Coatings may be applied using a variety of methods, including but not limited to plasma-spraying and sintering. Information developed using this test method may be useful for certain quality control and design purposes.
The test should not be considered to provide an intrinsic value for utilization directly in making calculations such as determining the ability of a coating to withstand specified environmental stresses.
Processing variables such as substrate preparation prior to coating, surface texture, coating technique variables or postcoating heat treatment variables may introduce a significant effect on the results of the tension test. The specimen being evaluated must be representative of the actual end use coating.
SCOPE
1.1 This test method covers tension testing of calcium phosphate and metallic porous coatings adhering to dense metal substrates at ambient temperatures. It assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in tension normal to the surface plane.
1.2 The values stated in inch-pound units are to be regarded as the standard.
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.
