The chapter presents recent advances in developing numerical models for multiscale simulation of the femur–endoprosthesis system for the case of hip resurfacing arthroplasty. The models are based on the movable cellular automaton method, which is a representative of the discrete element approach in solid mechanics and allows correctly simulating mechanical behavior of a variety of elastoplastic materials including fracture and mass mixing. At the lowest scale, the model describes sliding friction between two rough surfaces of TiN coatings, which correspond to different parts of the friction pair of hip resurfacing endoprosthesis. At this scale, such parameters of the contacting surfaces as the thickness, roughness, and mechanical properties are considered explicitly. The next scale of the model corresponds to a resurfacing cap for the femur head rotating in the artificial acetabulum insert. Here, sliding friction is explicitly computed based on the effective coefficient of friction obtained at the previous scale. At the macroscale, the proximal part of the femur with a resurfacing cap is simulated at different loads. The bone is considered as a composite consisting of outer cortical and inner cancellous tissues, which are simulated within two approaches: the first implies their linear elastic behavior, the second considers these tissues as Boit’s poroelastic bodies. The later allows revealing the role of the interstitial biological fluid in the mechanical behavior of the bone. Based on the analysis of the obtained results, the plan for future works is proposed.

In this work, powder immersion reaction assisted (PIRAC) chromium carbide coatings prepared on Q235 steel at 800 and 900°C were heat‐treated in vacuum at 900 and 1000°C, respectively. The effects of heat treatments on the phase compositions, microhardness, and oxidation behavior in the air of the as‐prepared PIRAC chromium carbide coatings were investigated. Under further heat treatments, Cr23C6 in the chromium carbide coatings was carburized due to the diffusion of carbon and transformed into Cr3C2 and Cr7C3 and subsequently, the microhardness of the coatings increased. The higher the heat treatment temperature, the higher the amount of Cr3C2 and Cr7C3 and the greater microhardness of the coatings. The as‐prepared and heat‐treated chromium carbide coatings experienced similar parabolic oxidation weight gains with time. Further heat treatments led to the oxidation‐induced weight gain and the parabolic oxidation rate constant decreased.

“…The coating obtained by PVD and CVD techniques have low adhesion and may delaminate under dynamic loading, while adhesion of the coating obtained by PIRAC is much higher. Furthermore, PIRAC allows depositing a wide range of compositions such as carbides, borides, and nitrides [4,5]. That is why PIRAC appears to be very promising for producing hardening coating of metal implants.…”

Friction between the moving parts of the endoprosthesis has a significant impact on the endoprosthesis operation time. Primarily, it concerns the endoprosthesis of hip and knee joints. To improve the tribological characteristics of the metal endoprosthesis, hardening nanostructured coatings are used. Usually, titanium and titanium alloys are used as metal, and titanium nitride is used as a coating. Herein, we propose an approach to multilevel modeling of the system “bone-endoprosthesis” which is based on the movable cellular automaton method and accounts for friction between the moving parts of the hip resurfacing endoprosthesis. We validated the models of the friction system materials using the instrumented scratch test simulation. Then, we simulated friction at the mesolevel, explicitly considering roughness of the coating. The results obtained at the mesolevel were used as tribological characteristics of the coating in the macroscopic model of the hip resurfacing endoprosthesis.
