FEM Simulation of Sclerometric Test of Nickel Aluminide Layered Coatings

Abstract

3D simulation by the finite element method (FEM) using MSC.Marc of sclerometric test with a conical indenter of a nickel aluminide intermetallic coating has been determined. The effect of the coating thickness and composition on the strain distribution has been determined. It is shown that an increase in the thickness of the coating makes it possible to reduce the magnitude of the maximum plastic strain. NiAl and Ni3Al coatings reduce maximum value of plastic strain and the penetration depth of indenter by 40% compared to a coating made of Ni2Al3.
