Effects of Plasma ZrN Metallurgy and Shot Peening Duplex Treatment on Fretting Wear and Fretting Fatigue Behavior of Ti6Al4V Alloy
A metallurgical zirconium nitride (ZrN) layer was fabricated using glow metallurgy using nitriding with zirconiuming prior treatment of the Ti6Al4V alloy. The microstructure, composition and microhardness of the corresponding layer were studied. The influence of this treatment on fretting wear (FW) and fretting fatigue (FF) behavior of the Ti6Al4V alloy was studied. The composite layer consiste...
متن کاملCharacterization of modified Ti6Al4V alloy after fretting-corrosion tests using near- field microscopy
Fretting wear and corrosion of Ti6Al4V alloys at the bone/implant stem interface produces the release of wear particles and corrosive ions from the stem into the surrounding tissue that can induce bone resorption. In this work, oxidation treatments at 500o and 700 oC for 1 h have been studied for increasing the friction-corrosion resistance at these interfaces. The friction-corrosion process of...
متن کاملDecorating Carbon Nanotubes with Nanoparticles
The unique, well-defined tubular structure of carbon nanotubes (CNTs) continues to attract interest. CNTs are fascinating materials for basic scientific research with the potential for several promising applications in catalysis, electronic devices and chemical biology. In recent years, many efforts have led to the development of versatile methods to modify CNTs to obtain derivatives with more ...
متن کاملCrack Behavior of the Aluminum Alloy 2024 Under Fretting Conditions
The initial stage of fretting fatigue crack growth is significantly influenced by tangential force induced by fretting action along the contact surface where a mixed-mode crack growth is involved. Fretting crack behavior of aluminum alloy 2024 was studied, taking into account the problem of contact asperities. Finite element was used for the determination of the stress field near the contact su...
متن کاملAn investigation of tensile strength of Ti6Al4V titanium screw inside femur bone using finite element and experimental tests
The geometric optimization of orthopedic screws can considerably increase their orthopedic efficiency. Due to the high geometric parameters of orthopedic screws, a finite element simulation is an effective tool for analyzing and forecasting the effect of the parameters on the load-bearing capacity of different types of screws and bones. Thus, in the present study, the tensile strength of a typi...
