In literature, few treatment parameters have been tested to analyze the surface integrity influence on fatigue properties. The self-heating method under cyclic loading is used to quickly determine fatigue properties by coupling them with intrinsic dissipation. Investigations on dissipation mechanisms of coating and substrate enable to develop self-heating models. That is the first step to build a lifespan forecast model based on temperature measurement to study shot-peening and coating influence on fatigue properties. %G English %2 https://hal-ensta-bretagne.archives-ouvertes.fr/hal-03761317/document %2 https://hal-ensta-bretagne.archives-ouvertes.fr/hal-03761317/file/1-s2.0-S2212827122004863-main.pdf %L hal-03761317 %U https://hal-ensta-bretagne.archives-ouvertes.fr/hal-03761317 %~ UNIV-BREST %~ ENSTA-BRETAGNE %~ CNRS %~ UNIV-UBS %~ UBS %~ ENIB %~ IRDL %~ ENSTA-BRETAGNE-MECA %~ ENSTA-BRETAGNE-PTR5-IRDL
