Simulation of the Load Bearing Capacity of hybrid Surface Modification Layer on TC4 Alloy Acquired by Plasma Immersion Ion Implantation and Deposition
The hybrid treatment involved two or more surface modification techniques has great potential to meet the new requests of practical applications, which are unobtainable through any individual surface modification method. However, up to now, the design of a hybrid surface modification layer is a difficult job for researchers. In order to study the wear resistance of the hybrid layer obtained by plasma immersion ion implantation and deposition (PIIID), a theoretical model to study the load bearing capacity of the hybrid layer was built. Compared with the substrate, the surface modification layer is very thin. Consequently, in order to save the simulation time and improve the precision, non-uniform grids were obtained in the simulation region. The simulation results reveal that the load bearing capacity of the TC4 substrate can be enormously improved by the PIIID hybrid treatment, because the transition layer can decrease the stress and strain at the interface. Compared with the sample with a single layer, the wear life of a sample by PIIID hybrid treatment was increased by 100 times.
