I am in need of information such as a formula to add in FEA calculation of the reduction in life cycle due to plating of tool steel.
Any info or DOE of plating on tool steel would be appreciated.
Please supply more information such as types of coatings and what the steel is used for.
The application is hand tools (wrenches).
Material is 4140 @ HRC 44
The plating is Ni strike/Bright Ni/ Tri Chrome
Electrolytic chrome plating can reduce the endurance limit by as much as fifty percent (50%). See Fundementals of Mechanical Design, 4th Ed., Shigley and Mitchell. How you apply fatigue to a FEA model is an interesting question.
