Titanium and its alloys present high interests for technological applications due to their high corrosion resistance, mechanical properties and biocompatibility. In combination with these remarkable characteristics, some Ti applications require specific surface properties that can be imparted with suitable surface functionalizations of the TiO(2) oxide layer. The present work aims to study the ...

The paper proposes an Induction Heating Principle using Full Bridge Inverter where a Single phase full bridge inverter consists of one rectifier, one capacitor, four mosfets and at the load side one induction heating rod is connected. So by this when any ac supply is given to the input side, we will get the square wave at the output side[1][3]. In this concept the induction heating rod is heate...

Cobalt ferrite (CoFe2 O4 ) nanoparticles have attracted significantly attentions for spintronics, recording media and bioapplications due to their unique magnetic and chemical properties. In this work, single phase CoFe2 O4 nanoparticles were synthesized at various coprecipitation temperatures (60, 80 and 90 °C) without post calcination. The effects of oleic acid as surfactant on the microstruc...

Periodic arrays of micrometer-sized ferromagnetic structures with perpendicular magnetic anisotropy are prepared by nanoindentation at the surface of a Fe(67.7)B(20)Cr(12)Nb(0.3) glassy ribbon initially showing in-plane magnetic anisotropy. The indented regions exhibit enhanced coercivity and saturation magnetization with respect to the surrounding nondeformed matrix. These effects are due to a...

The magnetic circuits of the developed high currents induction sensors for electric power supply systems devices transport are researched, analytical expressions flux in ferromagnetic connecting elements and voltage, replacement circuit elementary section, as well mathematical models sensors, obtained.

This paper presents the study of hardness profile of spur gear heated by induction heating process in function of the machine parameters, such as the power (kW), the heating time (s) and the generator frequency (kHz). The global work is realized by 3D finite-element simulation applied to the process by coupling and resolving the electromagnetic field and the heat transfer problems, and it was p...

The inverters are commonly used for medium power induction heating applications. In the process of induction cooking, a disc of metal is surrounded by a copper coil through which an alternating current is made to flow. The disc has a finite diameter and thickness. It is placed at a given distance from the coil and concentric to it. Secondary current is induced in the disc and this induced curre...
