An Ni2Al3 coating was prepared via the electrodeposition of nickel followed by pack aluminization. Polarization curve and electrochemical impedance spectroscopy were performed to study the room temperature corrosion behavior of the coating in a 3.5 wt. % NaCl solution. The long-term impedance of the coating was also investigated after immersion for 30 days. Results show that the Ni2Al3 coating ...

The phase composition and structure of stationary nickel-aluminum promoted catalysts have been studied. It is shown that the consists intermetallic compounds NiAl, NiAl3, Ni2Al3. Changes in microscopic alloys are determined. Modern methods for evaluating hydrogenation catalysts, as well analyzing raw materials products catalytic hydrogenation, established. highest performance characteristic who...

In this paper, the SiCp/Al composites were bonded via laser-induced exothermic reactions of a Ni–Al–Zr interlayer. The interlayer was designed based on its property and chemical compatibility with composites. influences composition bonding pressure joint microstructure shear strength investigated. Results indicated that high occurred in realized reliable products eutectic structure NiAl+Ni2AlZr...

The synergistic effect of Si and Ce addition on the oxidation resistance a pack cementation aluminide coating applied Ni-based IN738LC superalloy substrate was investigated in this study. structural thermal influences both Ce, focusing morphology, behavior, scale spallation tendency, are accordingly discussed based experimental results using X-ray diffraction (XRD), scanning electron microscopy...
