Testing Procedure Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least Continue the test until the components have been completely separated. Calcium phosphate and metallic coatings are used on a wide variety of metal substrates around the world, and commonly on orthopedic implants.
ASTM F1044 Shear Testing for Calcium Phosphate and Metallic Coatings
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Record the maximum load applied. Historical Version s – view previous versions of standard. Combining values from the two systems may result in non-conformance with the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
This newer version provides a means of testing and comparing different calcium phosphate thermal sprays to determine the high adhesion characteristics. Information developed using this test method may be useful for certain quality control and design purposes.
Measuring the adhesive quality of these products is essential due to their direct impact on implant degradation and bioactivity. We are confident that we have what you are looking for. Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least By means of our testing expertise and modular product design, we will help find the testing solution that is right for you.
It assesses the degree of adhesion of coatings to substrates, or astn internal cohesion of a coating in shear, parallel to the surface plane. ASTM F is a standard test method for shear testing calcium phosphate adhesion strength to metallic substrates under uniaxial shear stress.
The specimen being evaluated must asttm representative of the actual end-use coating. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F Apply the coating of interest to the face of each in the same manner as for actual production devices.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Link to Active This link will always route to the current Active asfm of the standard.
Next, apply a shear load to each test specimen at a constant rate of cross-head speed of 0. Have a question about conducting the test for this standard? We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental astj humidity chambers, furnaces, baths and custom solutions for unique applications.

Misaligned grips can easily introduce bending stresses that are not included in the typical stress calculation. Consider the right grip for the job. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Cure the adhesive agent and prepare a minimum of five test specimens.
