This paper assessed impact of dilution on the microstructure and properties of the Ni alloy In 625 deposited by Plasma Transferred Arc (PTA) on two substrates: carbon steel API 5LX70 (API 5L) and stainless steel AISI 316L. Differences due to the interaction with the substrate were maximized analyzing single layer coatings, processed with three deposition current: 120 A, 150 A and 180 A. Dilution was determined by the area ratio and Vickers hardness measured on the transverse section of coatings.

A gas metal arc welding robot was used to build a thin-walled component made of mild steel on a low-carbon substrate according to the AM principle. Thereafter, the specimens for observing microstructures and mechanical properties were extracted from the built thin-walled component. The microstructures of the specimen were observed by an optical microscope; the hardness was measured by a digital microhardness tester, and the tensile tests were carried out on a tensile test machine.

In this paper, the effects of the welding current in the WAAM process on the shape and the microstructure evolution of thin-walled low-carbon steel components were studied. For this purpose, the thin-walled low-carbon steel samples were built layer-by-layer on the substrates by using an industrial gas metal arc welding robot with different levels of the welding current. The shape, microstructures, and mechanical properties of the thin-walled samples were then analyzed.

In this study, high temperature oxidation-resistant NiCr/Al duplex coatings on carbon steel substrate have been fabricated by electrical wire arc-spraying process. The oxidation resistance properties of NiCr/Al duplex coating system have been evaluated at 800 °C during retention times of 1.5, 3.0, 4.5 and 6.0 hours. The morphology and chemical composition of their cross-sectional structures were investigated using scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS).

Reinforced concrete structures are damaged by salt attack, concrete carbonation, and sulfate attack, etc. The expansion stress by the corrosion of reinforcing steel causes crack in the cover concrete. Patch repair method is commonly applied to deteriorated RC structures. Deterioration mechanism of a patch-repair method in reinforced concrete is investigated through the experiment and analysis. The repair material selected is polymer-modified cement mortar re-emulsified by polymer resin.

The coatings present a compact structure, without any visible delaminations or defects. The morphology of the fracture of coatings is characterized by a dense structure, in some cases there is a columnar structure (Figs. 1, 2, 3). The fracture surface of the steel samples was examined and the deposited coatings show a sharp transition zone between the substrate and the coating.
