The notched coating adhesion specimen: a fracture test for coatings and accelerated screening test for adhesion
A simple adhesion test method is proposed to provide estimates of the debond toughness of adhesive bonds. Notched coating adhesion (NCA) specimens consist of single substrates coated with thin layers of adhesive. The coating is notched to induce initial debonds, and the specimen is then loaded in a …

A chemical and mechanical evaluation of interfacial fracture in dicyandiamide cured epoxy/steel adhesive systems
… double cantilever beam (DCB), fatigue DCB, and notched coating adhesion (NCA) interfacial fracture performances all increased. X-ray photoelectron spectroscopy (XPS) and tunneling electron microscopy (TEM) analyses of the failed specimens revealed that chemical changes were more prominent at the …

Durability of Polyimide/Titanium Adhesive Bonds: An Interphase Investigation
… temperature aging on the following systems: 1) Notched coating adhesion (NCA) specimens and 2) bulk samples of dispersed substrate particles in an adhesive matrix. The NCA test has the advantages of an accelerated aging geometry and a mode mix that leads to failure through the interphase, the …
