Abstract
The present study explores the effect of an electrodeposited nickel layer on Inconel-718 alloy produced using different additive manufacturing (AM) routes, like Laser Powder Bed Fusion (L-PBF), Electron Beam Powder Bed Fusion (EB-PBF), and Laser-Directed Energy Deposition (L-DED). Comparative analyses were conducted by characterizing the physical, mechanical, and surface properties of Ni-coated AM-built Inconel-718 alloy surfaces. Different microstructures of Ni coatings were observed for different AM-built surfaces of Inconel-718 alloy. Influence on the Ni-layer hardness was also noted, plausibly as a consequence of variations in the residual stress of coated specimens. The hardness of Ni-coated specimens was not correlated well with the scratch resistance due to the unique natures of the Ni layer interface with the substrate surface, depending upon the AM route adopted to produce the Inconel-718 alloy builds. A comprehensive analysis of the scratch failure in identically coated specimens built using different AM routes has also been discussed.
This study aims to investigate the microstructure, mechanical properties and corrosion resistance of nickel-aluminum bronze (NAB) coatings fabricated on Q235 steel using laser fused wire additive manufacturing.
The coatings were characterized using X-ray diffraction, electron backscatter diffraction and elec...

Ni-Co alloy coatings exhibit well-known properties, including mechanical, wear, and anticorrosive resistances, high magnetic performance, thermal stability at high temperatures, and good adhesion. However, these coatings exhibit hydrophilic characteristics, which hinder their applications under high-humidity condit...

Producing complex-shaped products of oxynitrides is one of the biggest challenges of the modern industry. The machining of those ceramics encounters challenges in terms of their physical and mechanical properties, such as their high brittleness and insulating electric properties. The problem may be solved by assisted e...

Three kinds of surface treatments, including permanganate, molybdate, and phytic acid conversion films, were fabricated on La-Ce mischmetal containing AM60B magnesium alloy. Their effects on the corrosion and tribological behaviors of the alloy in 3.5 wt% NaCl solution were systematically investigated via Mott–Schottky...
