We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. Measuring the adhesive quality of these products is essential due to their direct impact on implant degradation and bioactivity.
ASTM F Shear Testing for Calcium Phosphate and Metallic Coatings
Continue the test until the components have been completely separated. ASTM F is a standard test method for shear testing calcium phosphate adhesion strength to metallic substrates under uniaxial shear stress.
Combining values from the two systems may result in non-conformance with the standard. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F Force range of 5 kN to kN astk, 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.
We are confident that we have what you are looking for.
Zstm assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in shear, parallel to the surface plane. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Record the maximum load applied. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Testing Procedure Ast, a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least Historical Version s – view previous versions of standard.
Misaligned grips can easily introduce bending stresses that are not included in the typical stress calculation. Have a question about conducting the test for this standard?
ASTM F Shear Fixture for Testing Calcium Phosphate and Metallic Coatings | GF
Information developed using this test method may be useful for certain quality control and design purposes. Consider the right grip for the job. Link to Active This link will always route to the current Active version of the standard.
Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least This newer version provides a means of testing and comparing different calcium phosphate thermal sprays to determine the high adhesion characteristics.
Next, apply a shear load to each test specimen at a constant rate of cross-head speed of 0. Apply the coating of interest to the face of each in the ast, manner as for actual production devices. Cure the adhesive agent and prepare a minimum of five test specimens.
ASTM F1044 Shear Fixture for Testing Calcium Phosphate and Metallic Coatings | GF1044-788
Calcium phosphate and metallic coatings are used on a wide variety of f10444 substrates around the world, and commonly on orthopedic implants.
By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. The specimen being evaluated must be representative of the actual end-use coating. It is the responsibility of the user of aetm standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
