Biofilms forming on the surface of biomaterials can cause intractable implant-related infections. Bacterial adherence and early biofilm formation are influenced by the type of biomaterial used and the physical characteristics of implant surface. In this in vitro research, we evaluated the ability of Staphylococcus epidermidis, the main pathogen in implant-related infections, to form biofilms on...

A reliable bonding interface between steel and Ti alloy is required for producing a steel/Ti bimetal composite. In this study, molecular dynamic simulations diffusion welding experiments using the hot isostatic pressing process were conducted to study atomic at Fe-Ti interface. The simulation results indicate that layer thickness thinner in single crystals compared polycrystals same temperature...

Thermodynamic analysis and computations of the equilibrium solution for the multivariable secondary phase in steels have been conducted, based on the chemical equilibrium. Solid solution precipitation in the Ti–N–C microalloy steel for the secondary phase was analyzed, and its engineering application in the development of carburizing gear steels was investigated. The complete dissolution temper...

Bronization and carburization of fine-grain superplastic stainless steel is reviewed, and new experimental results for fine grain Ti88.5Al4.5V₃Fe₂Mo₂ are reported. In superplastic duplex stainless steel, the diffusion of carbon and boron is faster than in non-superplastic duplex stainless steel. Further, diffusion is activated by uniaxial compressive stress. Moreover, non-superplastic duplex st...

The field of biomedical materials plays an imperative requisite and a critical role in manufacturing a variety of biological artificial replacements in a modern world. Recently, titanium (Ti) materials are being used as biomaterials because of their superior corrosion resistance and tremendous specific strength, freeallergic problems and the greatest biocompatibility compared to other competing...

Orthodontic torque expression is the result of axial rotation of rectangular archwires within a rectangular bracket slot. This study investigates the effect of bracket material on torque expression. Torque exerted by a rotating archwire on each bracket will be measured as well as the relative deformation of each bracket slot. A total of 60 tests were performed where archwires were rotated withi...

the aim of the paper presented here is to develop the ti - micralloyed steel in otrer to oprtmize the mechanical properties after direct quenching from hot forging temperature. for this purpose, seven melts containing various amounts of titanium were prepared and cast in metal and sand molds. from the ingots, cast in metal mould, tractor links were produced by hot forging. the produced links we...

Music Structure Discovery (MSD) aims at estimating the underlying structure of a music track using observations of the audio signal. For this, a given time ti of a music track is supposed to belong to one of the following categories: • if ti contains information similar to its adjacent times, ti is said homogeneous [7] and belongs to a ”state” [8], • if ti is similar to a foreign time tj , and ...

Abstract The paper presents the results of comparative studies Ti-Al-N and Ti-Al-N-Ni coatings deposited on 20H13 (DIN 1.4021) steel, used as bearings in shipbuilding working a friction pair with UGET (carbon epoxy fabric) carbon plastic. It was found that addition nickel into composition significantly improves corrosion resistance sea water. study tribological characteristics indicates an incr...
