In the test to determine the tensile adhesive strength of thermally sprayed deposits, the specimen is loaded in tension.
The test is conducted to determine the strength of the coating and/or the strength of the bond between the spray deposit and the parent metal.
The test is used to evaluate the effects of parent metal and spray material, preparation of the surface of the workpiece, and the spraying conditions on the bond and adhesive strength of thermally sprayed coatings, or for routine supervision of the spray works.
Comparative statements are to be based in the test report.
NOTE The tensile adhesive test method is not recommended for very thin and porous depsoits. In this case, a bend test has proved to be more appropriate.
