Friction and lubrication of total hip replacement produced by 3D metal printing technology
Uhrová, Simona ; Horák, Zdeněk (referee) ; Vrbka, Martin (advisor)
This thesis investigates the tribological properties of total hip replacements manufactured by both traditional and additive technologies. The primary objective is to assess the impact of different manufacturing methods on friction and lubrication at the contact between the joint head and the acetabular cup. Techniques such as a pendulum joint simulator and optical methods are utilized to analyse the lubricant film formation and friction coefficient. The findings indicate that additively manufactured implants can potentially offer comparable or superior tribological properties compared to traditional methods, potentially leading to enhanced longevity and functionality of the implants. However, the need for appropriate surface treatment and further research into wear to ensure extended life and improved implant functionality is emphasised.
