Abstract
A behavior of interface of cold forging tool coated by hard film is analyzed by FEM. The indentation of a hemispherical tool of SUJ2 in JIS coated by electroplated coating of chromium into a cylindrical workpiece of S25C in JIS is performed. The proposed constitutive equations are implemented by the non-linear springs model at the interface. Calculated results show that the maximum interfacial normal displacement is observed at an immediately forward from the lip of the indentation, whereas maximum interfacial tangential displacement is at the immediately backward of the lip of the indentation.
