Predictive modelling of pulsating waterjet erosion of biometals

Anotace

Pulsating water jet technology offers to generate a specific 3D surface architecture, morphology, and roughness, which potentially enhances the rate of osseointegration. Using an effective and environmentally friendly method, it utilises pure water to obtain a medically clean surface without implant contamination by undesirable particles. Applying a pulsating water jet causes surface structuring and subsurface modification, mainly in terms of the dislocation substructure. Besides the effect on mechanical properties such as fatigue, hardness, or wear, surface properties such as wettability or surface energy are also affected. Achieving a desired functional surface with known properties requires appropriate tuning and optimising many process parameters. Predictive modelling of specific stages of erosion of biometals (Ti and AISI alloys) by pulsating water jets using machine learning approaches can largely contribute to predicting and selecting the optimal combination of the parameters and their levels, resulting in desired outcomes.
