“…By this process it is possible to enhance simultaneously the wear and corrosion resistance. The phase formed by PIII is called 'expanded' austenite [5,6] or γ N phase [7,8]. However, despite numerous investigations, the structure and formation of this phase is not completely understood.…”

Plasma immersion techniques of surface modification are known under a myriad of names.The family of techniques reaches from pure plasma ion implantation, to ion implantation and deposition hybrid modes, to modes that are essentially plasma film deposition with substrate bias.In the most general sense, all plasma immersion techniques have in common that the surface of a substrate (target) is exposed to plasma and that relatively high substrate bias is applied. The bias is usually pulsed. In this review, the roots of immersion techniques are explored, some going back to the 1800s, followed by a discussion of the groundbreaking works of Adler and Conrad in the 1980s. In the 1990s, plasma immersion techniques matured in theoretical understanding, scaling, and the range of applications. First commercial facilities are now operational. Various immersion concepts are compiled and explained in this review. While gas (often nitrogen) ion implantation dominated the early years, film-forming immersion techniques and semiconductor processing gained importance. In the 1980s and 1990s we have seen exponential growth of the field but signs of slowdown are clear since1998. Nevertheless, plasma immersion techniques have found, and will continue to have, an important place among surface modification techniques.

“…4 A wealth of research was devoted to explain the nature of expanded austenite, so far without a satisfactory understanding of its formation and structure. [5][6][7][8][9][10][11] According to literature, the expanded austenite is the main phase in different austenitic stainless steel surfaces after nitrogen ͑N͒ ion implantation. 12 It was recently suggested the presence of two different phases in the nitrided layer.…”

The magnetic properties and crystalline structure of expanded austenite obtained by ion beam nitriding of AISI 316 steel are investigated. Magnetic force microscopy reveals that the nitrogen expanded austenite has two different layers, an outermost ferromagnetic layer and a paramagnetic layer beneath it. Superimposing the nitrogen concentration profile determined by secondary neutral mass spectrometry and the magnetic force microscopy image, one can see that the paramagnetic-ferromagnetic transition takes place at the inflection point of the nitrogen concentration profile at about 14Ϯ 2 N at. %. Conventional and glancing angle x-ray diffraction suggests that nitrogen could occupy first tetrahedral interstitial positions ͑nitrogen-poor paramagnetic phase͒ and then, after saturation of Cr traps, octahedral interstitial positions ͑nitrogen-rich ferromagnetic phase͒. The ferromagnetic-paramagnetic transition is seen to be governed by Cr ͑traps͒-N interactions.
