The constituent elements of a machine, instrument or equipment are subject to different kinds of physical and/or chemical phenomena corrosive environments, high temperatures, contact loads, fatigue that can lead to the gradual loss of its functional integrity and the performance of the engineering system to which they belong, by degradation that usually starts on its surface Batchelor et al., 2002; ASM, IOM Communications, 2005.
