Corrosive Wear of Ti-6AI-4V Coupled With Ultrahigh Molecular Weight Polyethylene.
… Corrosive wear occurs in a wide range of situations from massive industrial machinery to the delicate metal pivot in a jewel bearing of a test meter. The problems of corrosive wear are not only limited to machinery but also to synthetic devices in the human body, e.g., orthopedic implant …

Influence of oxidation treatment on the corrosion behaviour of Ti-6AI-4V alloy
Titanium-6Al-4V is a greatly desired alloy due to its attractive properties and exceptional corrosion resistance. Surface modifications such as thermal oxidation (TO) and oxygen boost diffusion hardening (OBDH) improve the tribological properties and wear resistance of Ti-6Al-4V. However, surface …

The role of Hydrogen as a temporary alloying element during the manufacturing stages of Ti-6AI-4V by the powder metallurgy route
The aim of this research was to investigate the effects of using hydrogen as a temporary alloying element in the manufacturing of titanium (Ti) and Ti-6Al-4V by the powder metallurgy (PM) route using commercially pure titanium (CP Ti), titanium hydride (TiH2) and Ti-6Al-4V powders as starting …

Analysis of phase transformations in hydrogenated titanium metals by non-isothermal dilatometry
… was used as a temporary alloying element in CP Ti and Ti-6AI-4V. The microstructural evolution and phase transformations were monitored, before, during and after hydrogenation with in-situ dilatometric testing. Wrought CP Ti and Ti-6AI-4V specimens were pre-annealed and experienced four …

Surface modification of titanium-based alloys
… Oxygen Diffusion Hardening (ODH) have been investigated on two alloys of titanium, Ti-6AI-4V and Ti-6AI-7Nb (by weight). The first route involves a controlled atmosphere where argon saturated with water was used to transport water into the test pieces at elevated temperatures. The controlled …

Adhesion study of thermoplastic polyimides with Ti-6Al-4V alloy and PEEK-graphite composites
High glass transition (eg. 360 °C) melt processable thermoplastic polyimide homopolymers and poly(imide-siloxane) segmented copolymers were prepared from a number of diamines and dianhydrides via solution imidization, polydimethylsiloxane segment incorporation and molecular weight control with …

Structure-property behavior of novel high performance thermoplastic and thermoset structural adhesives and composite matrix resins
… and well-defined phthalimide endgroups via solution imidization. They were characterized by intrinsic viscosity, DSC, TGA, and thermomechanical measurements. Molecular weight control was successful and these polyimides were thermally stable via dynamic TGA up to 500°C. Flame resistance was …

A Comparative Study on Micro Electro-Discharge Machining of Titanium Alloy (TI-6AL-4V) and Shape Memory Alloy (NI-TI)
<p>The purpose of this research was to investigate the surface modifications that take place during the machining of NiTi SMA and Ti-6Al-4V with micro-EDM. This was done by creating an array of blind holes and micro-patterns on both work-pieces. To analyze the machined surface and investigate the …

A Study on the Micro Electro-Discharge Machining of Aerospace Materials
… Discharge Machining (EDM) is a non-traditional machining process that uses hundreds of thousands of minute electrical sparks per second to machine any electrically conductive material, no matter the hardness or how delicate it is. EDM allows a much greater range of design possibilities, …
