“…31,32 However, there are very few quantitative models that account for the development and growth of defects from smooth surfaces. Those models cited in the literature, [33][34][35][36] critically are dependent upon the application of Linear Elastic Fracture Mechanics (LEFM). This application of LEFM parameters to the modelling of microstructural dependent crack grow is considered to be inappropriate and a comment on this effect is given later.…”

It is now recognised that a complex load history may lead to structural damage that cannot be predicted on the basis of simple uniaxial loading conditions. The application of a single overload can induce sufficient crack growth such that the fatigue limit of a material is compromised. In a similar manner, it is possible to transgress the fatigue limit of a material by applying a number of corrosion cycles which lead to an increase in the size of the defect(s) present in the material beyond that of a 'threshold condition'. Damage accumulation within materials arises owing to the load and environmental history experienced throughout the lifetime of a component or structure. Furthermore, damage owing to load or environment in isolation impacts less on the durability of a structure/component, compared with that when conjoint effects of load and environment are experienced. This paper discusses the contribution that arises from environmental processes, such as corrosion, to final material failure. Synergy owing to corrosion and static/cyclic stress are discussed for both passive (stainless steel) and active (carbon steel) materials.

Influence of Substrate Material on Plain Fatigue and Fretting Fatigue Behavior of Detonation Gun Sprayed Cu-Ni-In Coating

et al. 2007

Cu-Ni-In coating was formulated on two substrate materials-Ti-alloy (Ti-6Al-4V) and Al-alloy (AA 6063) fatigue test specimens using detonation gun (D-gun) spray process. Coating on both substrates was dense with low porosity, high hardness, and high surface roughness. Relatively higher surface compressive residual stress was present at the coating on Ti-alloy specimens. In case of the coating on Al-alloy samples, tensile residual stress was also present in some places. Uniaxial plain fatigue and fretting fatigue experiments were conducted on uncoated and coated specimens. The detrimental effect of life reduction due to fretting was relatively larger in the Al-alloy compared to the Ti-alloy. While Cu-Ni-In coating was found to be beneficial on the Ti-alloy, it was deleterious on the Al-alloy substrate under both plain fatigue and fretting fatigue loading. The results were explained in terms of differences in the values of surface hardness, surface roughness, surface residual stress, and friction stress.
