Coatings shear testing
WebThe shear test method ( Fig. 6.4 (b)) uses a similar approach, but the load is applied to the bonded coating layer parallel to the interface ( Wei et al., 1999 ). The test depends on the use of a sufficiently strong bonding agent to remove the coating from the substrate with an applied shear stress.
