The Effects of Thin Compressive Films on Indentation Fracture Toughness Measurements,
Abstract
Thin compressive films have been shown to decrease the lengths of radial cracks produced by a Vickers indentation in a variety of nonmetallic materials. The intrinsic stress of submicron thick films deposited by reactive ion beam sputtering was measured by a cantilever technique. The change in the apparent identation fracture toughness of the coated material was correlated with film thickness and stress, identation load, and the nature of the substrate.
