HVOF Bond Strength
All coatings were prepared using standard Set A parameters, test method per ASTM C633 on 1020 carbon steel substrates with grit-blasted surface preparation.

*In these samples, the failure was in the epoxy. Therefore, the actual bond strength of these coatings is greater than the figures shown, but, it is impossible to determine by how much.
Bond data for JK™ 114 powder was also developed on a substrate of 4340 steel hardened to Rc55-60. Some applications for the JET KOTE™ II System are under development that would be applied to hardened substrates (i.e., cutting knives and blades found in various industries such as paper and plastics). The results show bond strength as good as on a 1020 carbon steel substrate.
The coating was prepared with standard Set A parameters.
