Summary
A model system consisting of a CrN coating approximately 5 μm thick deposited by magnetron sputtering on cartridge brass was deformed under uniaxial tension to study the failure mechanisms of the coating. The flow stress of the brass substrate was varied by annealing the cold rolled material to produce a variety of grain sizes. The evolution of cracks in the coating as a function of flow stress was studied by optical microscopy experiments. These results are explained in terms of current models of thin film cracking on ductile substrates.
