ASTM F1044 PDF

A number in parentheses indicates the year of last reapproval. It assesses thedegree of adhesion of coatings to substrates, or the internalcohesion of a coating in shear, parallel to the surface plane. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.

Calcium phosphate and metallic coatings are used on a wide variety of metal substrates around the world, and commonly on orthopedic implants. Measuring the adhesive quality of these products is essential due to their direct impact on implant degradation and bioactivity. This newer version provides a means of testing and comparing different calcium phosphate thermal sprays to determine the high adhesion characteristics.

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. Apply the coating of interest to the face of each in the same manner as for actual production devices. Next, apply a shear load to each test specimen at a constant rate of cross-head speed of 0. Continue the test until the components have been completely separated.

Record the maximum load applied. Consider the right grip for the job. Misaligned grips can easily introduce bending stresses that are not included in the typical stress calculation. By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F Recommended Test Machine Force range of 5 kN to kN 1, lbf to , lbf 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 Recommended Testing Accessories Designed in accordance with ASTM F Compression, compression-shear, and torsion models available.

ASTM F1044 Shear Testing for Calcium Phosphate and Metallic Coatings

Shaktigami Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM F is a standard test method for shear testing calcium phosphate adhesion strength to metallic substrates under uniaxial shear stress. 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. Misaligned grips can easily introduce bending ast that are not included in the typical stress calculation.
