in situ synthesis of tic ti composite coating by high frequency Induction cladding
Journal of Alloys and Compounds, 2017Co-Authors: Wei Zhang, Hong Wang, Zhicui SongAbstract:Abstract The in-situ formation of TiC/Ti composite coating was achieved by Induction cladding (IC) approach. The powder mixture of 70 at% Ti and 30 at% graphite were preplaced on a Ti6Al4V substrate and irradiated with a high frequency Induction Heating Coil in Ar atmosphere. The cladded coating exhibited a practically dense and pore-free microstructure with metallurgical adherence to the substrate. Fine titanium carbides (TiC) were uniformly formed in the coating, which were confirmed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and transmission electron microscope (TEM) analysis. Two temperature peaks within the coating indicates the Induction cladding process is different from the point Heating sources. Dissolution-precipitation mechanism is used to explain the formation of the composite coating and the in situ synthesis of the TiC particle reinforcements. The nanoindentation hardness of the TiC particles is about 22 GPa, which makes the microhardness of the composite coating (600 HV 0.2 ) nearly twice the microhardness of the Ti6Al4V substrate (340 HV 0.2 ). The hardness evolution of the composite coating is evaluated by the rule of mixtures and the predicted results are consistence with the measured ones.

Induction heated pressure vessel system and method for the rapid extraction of lipids and trace polar micronutrients from plant material
Food and Bioproducts Processing, 2001Co-Authors: Larry F Stikeleather, J A SingletonAbstract:Alaboratory extractor has been designed and constructed that selectively extracts polar and non-polar components from oilseeds and other matrices using elevated pressure and temperature. The extractor is comprised of a 403 stainless steel pressure vessel heated by an electromagnetic Induction Heating Coil. An Induction Heating control circuit, from a commercially available Induction cooker, is used to drive a custom wound Heating Coil designed to cradle the pressure cell. The advantages of this system include low initial cost, greatly reduced solvent consumption, shorter extraction times, quantitative lipid recovery, use of multiple extraction solvents, and reduction in cost per sample. Neutral lipids were extracted from peanut and soybean meals in 50 minutes by this rapid extraction method compared to 1440 minutes required to extract the comparable amount of neutral lipids from a similar sample using the Soxhlet extraction method. Methodology and data on micronutrient extractions are also presented to verify extractor performance.

designing of suitable construction of high frequency Induction Heating Coil by using finite element method
IEEE International Magnetics Conference, 2005Co-Authors: A Boadi, Yuji Tsuchida, Takashi Todaka, Masato EnokizonoAbstract:This paper describes the three-dimensional (3-D) modeling of an Induction Heating system. To realize the suitable construction of a high-frequency Induction Heating Coil, numerical computations of eddy currents and heat conduction have been carried out by using the finite-element method (FEM) and also taking into account the dependence of material properties on temperature. For a high-frequency Induction Heating Coil, which is normally applicable for heat treatment, the tubular solenoid design is the most appropriate due to its high Coil efficiency. Coil efficiency is that part of energy delivered to the Coil, which is transferred to the workpiece. Besides Coil efficiency, the Heating pattern and the production rate are also important. As the Heating pattern reflects the Coil geometry, optimal Coil design is a prerequisite to attain the desired Heating. Several modifications, such as spacing in between Coil turns, the motion of the workpiece relative to the Coil, and dimensional parameters, were carried out until optimal design was achieved.
