Tumour treatment by direct electric current: electrode material deposition

Direct current electrotherapy was demonstrated to be an effective and relatively inexpensive local treatment of murine solid subcutaneous tumours. The insufficient knowledge of the mechanisms involved hinders its more extensive use in clinical oncology. Attempts were made to establish the correlation between the effectiveness of electrotherapy and deposition of the electrode material in the tum...

Component repair using laser direct metal deposition

Recent studies have indicated that laser direct metal deposition can be used for repairing deep or internal cracks and defects in metallic components. In order to implement the method, it is necessary to machine a groove or slot to the depth of the defect and refill it. This work investigates advantages and potential problems with the technique and compares the results from using two different ...

Feasibility of Building an Overhang Structure Using Direct Metal Deposition

This paper summarizes a theoretical and an experimental approach to employ the Direct Metal Deposition (DMD) process to adjudge the feasibility of depositing overhang features. The DMD process is a process capable of directly manufacturing a fully dense metal part without the use of any intermediate steps. This process, comprised of a laser deposition setup coupled with a 5-axis CNC milling sys...

Direct Deposition of Metal Film Patterns Using Nitrogen Laser

Rhenium, gold and platinum film micropatterns were obtained by the LCVD method on the surface of silicon and glass substrates from vapors of R ~ z ( C O ) ~ ~ , (CHg)~Au(dpni), P t ( l~fa)~, respectively. The heated reaction chamber at atmospheric pressure with a flow of an inert gas-carrier was used. The high marginal sharpness and the thickness uniformity of deposited films was provided by th...
