3. Conclusion

Mechanical surface treatments are a category of treatments that have been used by the mechanical engineering, automotive, aeronautics and space industries for a very long time. While know-how has evolved over the years, the actual integration of mechanical surface treatments into advanced design is still in its infancy. To this day, they are still seen as a range of back-up processes that can be introduced at the end of the design chain, or as a treatment that extends the life of a product on the market without the need for a new design. However, thanks to research carried out over the last twenty years, we now have a full range of tools for simulating residual stresses and fatigue life of associated mechanical parts. Advances in stress analysis methods give us access to the distribution of residual stresses in depth. This is very important both for optimizing the range of processes to...
