The development of ion or plasma Nitriding started in the 1930s but was not commercially used until the 1970s.All three Nitriding methods have advantages and the selection of a particular method depends on the specific application of the nitrided component (2, 3). Plasma Nitriding can be used for the ium Gas bottle and many other fuel

Nov 15, 2018 · Laser shock peening was primarily adopted as a pretreatment prior to plasma nitriding for 42CrMo steel. It was found that laser shock peening had obvious enhancement effect on plasma nitriding. The thickness of compound layer and effective hardening layer could be effectively improved under the same plasma nitriding condition, which was about twice thicker as that of conventional plasma nitriding. Biological Behaviour and Enhanced Anticorrosive Aug 19, 2015 · The influence of gas nitriding surface treatment on the superelastic Ti-23Nb-0.7Ta-2Zr-0.5N alloy was evaluated. A thorough characterization of bare and nitrided Ti-based alloy and pure Ti was performed in terms of surface film composition and morphology, electrochemical behaviour, and short term osteoblast response. XPS analysis showed that the nitriding treatment strongly influenced the
Mar 25, 2021 · As a classic hard coating, titanium aluminum nitride (TiAlN) coating is widely applied in the aviation field due to its extremely high hardness and strength. Unfortunately, the large difference in hardness and thermal expansion coefficient between the coating and the substrate could also lead to the reduction of bonding force. In this paper, Double-glow plasma nitriding (DGPN) pretreatment Enhancing Forging Dies' Durability with Ion NitridingSep 17, 2020 · Gas- or plasma-assisted nitriding treatment is known for increasing durability of forging dies by a factor of 1.2-6, depending on the stress and the production volume of the hot working dies . Nitrided layers formed in the hot-working steels used for building such tools has increased hot strength and thermal stability.
Abstract In this work, novel duplex plasma nitriding is carried out on AISI-304 steel at fixed temperature of 400 °C, using aluminum and austenite steel cages. The influence of (1-h) aluminum cage nitriding is investigated before (pre) and after (post) the (4-h) austenite steel cage nitriding. The treated samples are characterized using Vickers hardness tester, X-ray diffraction, scanning Low-temperature plasma nitriding of titanium layer on Ti A nanostructured surface layer was fabricated on titanium layer of a Ti/Al clad sheet composite by means of the surface mechanical attrition treatment (SMAT). The low-temperature plasma nitriding treatment of the SMAT sample was investigated in comparison with the coarse-grained sample by using structural analysis (X-ray diffraction, scanning electron microscopy, and transmission electron
Made available by U.S. Department of Energy Office of Scientific and Technical Information ON THE PLASMA NITRIDING RATE OF 42CrMo STEEL-- With reference to their previous experiment on plasma nitriding of 42CrMo steel, and relevant mathematical relationships, and with the help of computer in processing the observed data, the authors formulated their mathematical model for diffusion layer, chemically combined layer, and temperature control.In this manner,they succeeded in computerization of the parameters of plasma nitriding.
