The effect of temperature on magnetic Barkhausen noise (MBN) can be divided into two types: the direct itself and indirect thermally induced stress. theoretical model is proposed in this paper to describe effects MBN signal. For case considering only, analytical allows prediction profile, and, based model, a simple linear calibration curve presented evaluate amplitude quantitatively. While for ...

Cathodic Protection is the " Electrical " method of controlling and stopping the rust process of underground/submerged steel pipelines and structures.

The performances of the synchronous reluctance motor are essentially dependent on the magnetic dissymetry of the machine, respectively of its rotor, as in [1], [2], [3], [4], [5], [6]. The last one is made from grain-oriented steel laminations, alternating with insulation and non-magnetic material. The fastening is realized with clamping plates and screws made from non-magnetic material (brass ...

This paper presents the characterization and analysis of a 16.8%-efficient 18 um silicon solar cell on steel substrate. Photoluminescence (PL) is used to monitor the solar cell’s fabrication step by step, and a correlation between PL intensity and implied open circuit voltage is established. PL images yield spatially resolved maps of key electrical parameters such as dark reverse saturation cur...

We report the synthesis of superhydrophobic coatings for steel using carbon nanotube (CNT)-mesh structures. The CNT coating maintains its structural integrity and superhydrophobicity even after exposure to extreme thermal stresses and has excellent thermal and electrical properties. The coating can also be reinforced by optimally impregnating the CNT-mesh structure with cross-linked polymers wi...

the permeability and the power losses are very important properties of non-oriented electrical sheets. the existence of a crystallographic easy magnetization plane and direction makes the distribution of grain orientations (texture) the most important factor in the improvement of the quality of a soft magnetic material [1]. the optimum texture is a fibre texture in which all the grains have a <...
