Finite element investigation of nano-indentation of coated stainless steel

An finite element analysis was used to investigate the nano-indentation testing process in different kinds of coating on 316 Stainless Steel, in order to determine the properties of coating material and to and investigate the influence of different of the material coating materials on 316 Stainless Steel. The finite element analysis was based elastic-plasticity properties of material. The results were three main points: 1) the simulation force-depth relationship was agreed with the experimental force-depth relationship for 316 stainless steel; 2) the range of Modulus of Elasticity for specific coating was determined as between 5GPa to 60GPa; 3) the influence of the thickness of coating material on the force indentation depth relationship was investigated. The project offers suggestions to further design of coating process research.
