Expert Commentary
The benchmark for Adhesion or Cohesive Strength of Thermal Spray Coatings. A loading fixture is bonded to the coating and pulled in tension. The critical technical variable is the alignment of the pull. If the loading blocks are not perfectly coaxial, the coating will peel at the edge, giving a false low reading. MTO provides a self-aligning Spherical Seat tension jig that ensures the force is perfectly perpendicular to the coating plane. This is vital for jet engine turbine blade coating validation.
