Abstract

Surface damage and wear in materials engineering and medical implants, both external and internal, in manufactured materials, or power plants causes economic loss, unnecessary plant stops, medical-surgical difficulties, and post-operation severe functional troubles. In the case of power plants, of operational time in modifications or repair. The wear in power plants is caused mainly by solid particles and water droplets. In medical technology, erosion and corrosion of implants, together with histocompatibility of the materials, creates serious surgical and post-surgical inconvenients. Erosion and corrosion of protective coatings constitute a number of significant engineering difficulties. “Trial and error” type methodology to improve the materials design is rather expensive, inaccurate and time consuming. Inverse methods [4, Casesnoves, 2017] and mathematical optimization and modelling are the current tools for overcome these difficulties. Mathematical modelling through optimization methods can solve partially/totally these engineering complications/difficulties, and reduce the experimental/tribotesting period. In medical technology/devices biotribotesting is more complicated because the clinical trials, in-vitro, and in-vivo tests require animal or human specimens and in the last stages of these clinical trials the medical ethics implies a carefully and cautiously upper-level phase to obtain the final device/implant ready for surgery or orthopedics. In this paper we provide a brief review of the current classified erosion and/or corrosion models and, additionally, detailed modern optimization methods for precise modelling of given applications. The Integral-Differential Model/Method is presented (Casesnoves, 2017), followed by the Stratrified Model (Casesnoves, Kulu, Surzhenkov, 2018). Bioengineering models for medical devices in hip implants, in erosion, are computationally-graphically optimized with specific algorithms. Ever the precision, from optimization algorithm to laboratory data implementation, computational optimization trials for an erosion models are presented with brief software details/approximations. Graphical Optimization (Casesnoves, 2017) for models is presented in materials tribology and biotribology with sharp images.
