To improve the manufacturing quality of welded structures, to prevent failures at weld joints and to predict their lifetime, measurements of the residual stresses generated by welding in the structures are extremely useful. The residual stresses may reduce the component life due to phenomena that occur at low applied stresses such as brittle fracture, fatigue and stress corrosion cracking. Weld...

Titanium alloy (Ti-6Al-4V) can be economically machined with high-pressure coolant (HPC) supply. In this study, an artificial neural network (ANN) model was developed for the analysis and prediction of tool wear parameters when machining Ti-6Al-4V alloy with conventional flow and high-pressure coolant flow, up to 203 bar. Machining trials were conducted at different cutting conditions for both ...

Thigh pain after uncemented total hip arthroplasty (THA) remains a controversial topic. Our objective was to assess the effect of material composition in the development of thigh pain after primary THA. A cohort of 241 primary THAs was followed for a minimum of 2 years. All patients received identically shaped tapered cementless femoral components; the first half received a Cr-Co-Mo implant and...

The next great wave of innovation and development for implantable medical devices focuses on surface engineering. This would enhance their performance, restore lost functions and ultimately reduce pain. Biomimetic coating is a promising approach, used in that concern. In the present work, an attempt was made to develop the function of the biomimetic coating rather than the classical biocompatib...

Titanium alloys are extensively used in various fields of engineering, medicine, aerospace, marine due to its excellent mechanical properties. Its usage is more pronounced today in the field of biomedical implants due to its superior biocompatibility, corrosive resistance and high strength to weight ratio. It has poor abrasive wear resistance due to high coefficient of friction and low thermal ...

The use of artificial implants provides a palliative or permanent solution for individuals who have lost some bodily function through disease, an accident or natural wear. This functional loss can be compensated for by the use of medical devices produced from special biomaterials. Titanium alloy (Ti-6Al-4V) is a well-established primary metallic biomaterial for orthopedic implants, but the toxi...

Surface Plasmon Polaritons (SPPs) have been known since the late 1950s with the work of Richie [1]. Today most research with these surface waves is aimed at production of subwavelength components in an attempt to merge the subjects of electronics and photonics on a nanometer scale. However, the features produced by SPPs could have uses in direct engineering applications due to their surface tex...

This study investigated the microstructure evolution of TiC/Ti-6Al-4V matrix composite produced using a 1073 nm continuous wave (CW), IPG Ytterbium fibre laser. The influence thermal gradient, overlap, and re-melting previous layers on TiC/Ti6Al4V samples was analyzed scanning electron microscope (SEM). showed that are composed undissolved TiC, in-situ TiC (eutectic primary TiC), α Ti β Ti. Whi...

Near-net shape processes, such as laser metal deposition (LMD), offer a unique combination of process flexibility, time savings, and reduced cost in producing titanium alloy components. The current challenge in processing titanium alloys using LMD methods is understanding the complex microstructural evolution as a part is fabricated layer by layer. The microstructure is affected by the repeated...

STATEMENT OF PROBLEM The poor chemical bonding of a denture base resin to cast titanium framework often introduces adhesive failure and increases microleakage. PURPOSE This study evaluated the shear bond strengths of a heat cure denture base resin to commercially pure titanium, Ti-6Al-4V alloy and a cobalt-chromium alloy using two adhesive primers. MATERIAL AND METHODS Disks of commercially...
