This document specifies the procedure to determine t
he tensile adhesive strength and/or the coating strength
of a thermal sprayed coating under tension load in the
direction normal to the surface of the coating by
applying a tensile test. Using this method compar
ability of the test results is ensured.
The test is intended to determine the tensile adhesive
strength between the spray coating and the parent
metal or between the bond and top coat and/or of the co
hesive strength of the conc
erned coat of the coating
This test is sufficient to compare coatings manufactur
ed using same or similar spray materials and processes
with each other. The tensile adhesive strength test is not intended to provide set values for calculation
purposes of loadings.
The test is used to assess the effects of the preparat
ion of the part’s surface to be coated, the spraying
conditions, and the process parameter on the adhesive st
rength of thermal spray coatings or to monitor the
constancy of the manufacture and the spray works.
In that way a decisive contribution can be made to
process and quality assurance of production.
