Additive manufacturing and gas technology applications

As the demand for additive manufacturing (AM) products has steadily increased, so have the many enabling technologies including laser powder bed fusion, laser metal deposition (LMD), wire arc additive manufacturing, thermal spraying, and electron beam melting (EBM). All of these rely — directly or indirectly — on industrial gases such as nitrogen, argon, and helium. […]

Plasma/ion nitriding for enhancing component properties

Thermochemical surface treatments, such as plasma/ion nitriding, are effective ways of enhancing the mechanical properties of ferrous and titanium alloy parts [1, 2]. Through the thermochemical treatment, compound zone and/or diffusion layers are formed that reduce wear, friction, bending, and rolling contact fatigue (RCF). Additionally, with the sufficiently thick compound zone, corrosion resistance properties can […]

Using vanadium alloys

Vanadium is a commonly used alloying element in high strength low alloy (HSLA) steels because it improves strength and wear resistance through the precipitation of vanadium carbonitrides. The use of vanadium in powder metallurgy (PM) steels has so far been limited. A previous study demonstrated that by using a vanadium alloyed PM steel, the total […]
