Leterrie The present work investigates the saturation damage state of a two-layer coating on a substrate (layer 1/layer 2/substrate) under uniaxial tensile loading in order to derive expressions for the interfacial strength...

Microcasting Shape-Deposition-Manufacturing is an approach to Solid-Freeform-Fabrication (SFF) process which is a novel method for rapid automated manufacturing of near-net-shape multi-material parts with complex geometries. By this method, objects are made by sequentially depositing molten metal droplets on a substrate and shaping by a CNC tool, layer by layer. Important issues are concerned w...

Electrodeposition of CuInSe2 (CIS) and CuInAlSe2 (CIAS) from aqueous solution has been systematically investigated by cyclic voltammetery implementing different scan rates. It has been shown that electrodeposited CIS and CIAS have been formed on the substrate through electrochemical-chemical interaction of reduces species on the substrate.  From the obtained results, it could be inferred that I...

Abstract: The possibility of vanadium carbide coating formation on AISI L2 steel was studied in molten salt bath containing 33 wt% NaCl- 67 wt% CaCl2. In this research, the effects of time, temperature and bath composition on growing layer thickness were studied. The vanadium carbide coating treatment was performed in the NaCl-CaCl2 bath at 1173, 1273 and 1373 K temperatures for 3, 6, 9 hours a...

The low cost, high efficiency, single-feed microstrip antenna with a two-layer substrate for circular polarization (CP) is presented. A new CP design of a singlefeed nearly square patch with two truncated square corners is also described here. The two-layer substrate consists of an FR4 dielectric layer and a foam layer. The effects of the foam substrate on the impedance bandwidth, axial ratio, ...
