Study the effect of corrosion on fatigue strength of alloy steel (CK45) using in crank shaft under shot peening processes

Author

Abstract
In this study fulfilled, prediction of fatigue life for alloy steel (CK45) at the several cases:
As received after shot peening after immersed in 36% Mgcl2, 30 day shot peening for specimens after corrosion.
All tests carried out under constant amplitude load, rotating bending at stress ratio (R = -1) and room temperature.
The following conclusions are obtained:
The fatigue strength increased 11% with shot penning process The fatigue strength decreased 18% after corrosion in corrosive medium The fatigue strength increased 14% with shot penning process after immersed in corrosive medium.
