It assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in shear, parallel to the surface plane.
Record the maximum load applied. Have a question about conducting the test for this standard? It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory f10444 prior to use.
Apply the coating of interest to the face of each in the same manner as for actual production devices.
Calcium phosphate and metallic coatings are used on a wide variety of metal substrates around the world, and commonly on orthopedic implants. The specimen being evaluated must be representative of the actual end-use coating. 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.
Referenced Documents purchase separately The documents listed below are asrm within the subject standard but are not provided as part of the standard. Measuring the adhesive quality of these products is essential due to their direct impact on implant degradation and bioactivity.
Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least We are confident that we have what you are looking for.
ASTM F is a standard test method for shear testing calcium phosphate adhesion strength to metallic substrates under uniaxial shear stress. Historical Version s – view previous versions of standard. Misaligned grips can easily introduce bending stresses that are not included in the typical stress calculation.
Information developed using this test method may be useful for certain quality control and design purposes. Next, apply a shear load to each test specimen at a constant rate of cross-head speed of 0. Combining values from the two adtm may result in non-conformance with the standard.
Continue the test until the components have been completely separated. Link to Active This link will always route to the current Active version of the standard.
We offer machines, apparatus, f10444, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. This newer version provides a means of testing and comparing different calcium phosphate thermal sprays to determine the high asym characteristics.
By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. Testing Procedure Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least Cure the adhesive agent and prepare a minimum of five test specimens.
