Thin Film Coatings for Biomaterials and Biomedical Applications 

It is important to determine stresses in thin films in relation to mechanical stability as a result of the deposition process and the temperatures involved. The stress developed in a film is made up of three components. The first component is intrinsic, which is the result of factors such as deposition, structure, and mode of growth the second is the result of the mismatch in thermal expansion between film and substrate and the third is related to externally applied stresses (Lepienski et al., 2004). Once the values of intrinsic stress ( r(intrinsic)) thermal stress ( (thermal)), and externally applied stress ((T(extemal)) are determined, the stress developed within a film can be calculated using the following equation
