Influence of high-cycle fatigue actions on physical-mechanical state of the plane samples hardened case

The influence on the characteristics roughness and microhardness of high-cycle fatigue actions of the plane samples from the alloy EI698 VD, previously hardened in the rate of the air shot blasting, was researched. It became clear, that microhardness correlates with the value of the compressing remaining tensions at hardened case, but roughness doesn't depend on rates and character of fatigue actions.
