Optimization of a transferred arc reactor for metal nanoparticle synthesis
The demand for metal nanoparticles is increasing strongly. Transferred arc synthesis is a promising process in this respect, as it shows high production rates, good quality particles and the ability of up-scaling. The influence of several process parameters on the performance of the process in terms of production rate and particle size is investigated. These parameters are the electrode design ...
متن کاملDestruction of organo-halogenated compounds by DC non-transferred arc plasma
The actual technologies for the destruction of organo-halogenated substances are reviewed and compared with the emerging plasma processes based on the non transferred arc plasma torches. The associated costs are presented.
متن کاملPROCESS CONTROL AND DEFECTS IN Ti-6Al-4V ADDITIVE MANUFACTURING, USING PLASMA TRANSFERRED ARC (PTA) TECHNIQUES
Defects during Plasma Transfer Arc (PTA) beam fusion additive manufacturing (AM) processing of Ti-6Al-4V, including lack of fusion, porosity variations, and solidification cracking, have been monitored using near infrared (1.62 μm) imagery at 300 Hz, 300 μm spatial resolution and melt pool sizes of greater than 12μ. The temperature evolution exhibits a periodic temperature modulation of more th...
متن کاملEffect of Asymmetrical Distribution of Current Density on the Three-Dimensional Non-Transferred Arc Plasma Torch
In this study, three-dimensional steady-state non-transferred arc plasma torch was investigated by computational fluid dynamics (CFD) method with user defined function (UDF). Two-equation current density profile was developed to simulate the complex plasma flow inside the torch. The effect of asymmetric distribution of current density (ADCD), particularly the deviation distance (distance betwee...
متن کاملMicrostructural Study of 17-4PH Stainless Steel after Plasma-Transferred Arc Welding
The improvement of the surface qualities and surface hardening of precipitation hardened martensitic stainless steel 17-4PH was achieved by the plasma-transferred arc welding (PTAW) process deposited with Co-based alloy. The microstructure of the heat affected zone (HAZ) and base metal were characterized by optical microscope (OM), scanning electron microscope (SEM) and transmission electron mi...
