Intercalation of Mg into epitaxial graphene was investigated using chemical vapor deposition (CVD) and physical vapor deposition (PVD) for the formation of n-type doped graphene. Scanning electron microscopy and atomic force microscopy indicate PVD has significantly greater metal deposition and surface roughness compared to the CVD process. Findings from x-ray photoelectron spectroscopy infer the formation of Mg intercalated quasi-freestanding epitaxial graphene indicated by shifting of the SiC peak in C 1s spectra. This is substantiated by visual evidence from scanning tunneling electron microscopy of one or more layers of Mg residing underneath EG. Furthermore, an invariant 2D peak position in Raman spectra taken over a 7-day period in ambient conditions support arguments of the stability of electron doped Mg-intercalated epitaxial graphene. CVD offers a cleaner and smoother surface compared to PVD due to improved control over when the substrate is subjected to Mg exposure, but PVD allows for greater Mg concentrations per minute that may increase the amount of intercalated metal.

MP35N® NACE Nickel Cobalt Alloy is a Multiphase® cobalt nickel-based superalloy, consisting of 35% Nickel and 35% Cobalt. MP35N NACE Nickel Cobalt Alloy is produced using a 2-step melting process, the first step is a vacuum induction melted (VIM), this is then followed by vacuum arc remelted (VAR). This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N NACE Nickel Cobalt Alloy is produced specifically for use in sour gas (H₂S) service. It is produced by aging, to restrict hardness and limit the susceptibility to cracking in these environments.

This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N Nickel Cobalt Alloy can be aged to increase mechanical properties beyond those of stainless and nickel alloys, without sacrificing corrosion resistance. MP35N Nickel Cobalt Alloy can be supplied per AMS 5844 (Sol Treated and Cold Worked), and can then be age hardened to increase mechanical properties.

Cobalt based metals are alloyed with chrome, nickel, and tungsten. Due to the high cost of these alloys, they are used where severe conditions prevail and require high temperature strength and hardness, excellent wear, galling, corrosion, and/or erosion resistance.

Due to the high chromium content (25% – 30% for the grades listed below) cobalt-based alloys provide superior corrosion resistance at high temperatures. The materials are more weldable than nickel-based alternatives. While not as strong as nickel alloys at lower temperatures, above about 1700°F / 930°C cobalt alloys show higher strength. Nickel melts at 2651°F / 1455°C while cobalt melts at 2723°F / 1495°C.
