“…Alloys with elevated concentrations of Cr, Mo, and N (e.g., 904L), as indicated by the pitting resistance equivalent number (PREN) index, are generally more resistant to crevice corrosion. [118][119] Copper and tin additions to austenitic SS can increase passivity and pitting resistance in certain environments, such as sulfuric acid. 108 SS 304LSC and 316LSC are alloys of this type that are commercially utilized for powder metallurgy part production.…”

The corrosion of additively manufactured (AM) metallic materials, such as stainless steels (SS), is a critical factor for their qualification and reliable use. This review assesses the emerging knowledgebase of powder-based laser AM SS corrosion and environmentally assisted cracking (EAC). The origins of AM-unique material features and their hierarchal impact on corrosion and EAC are addressed relative to conventionally processed SS. The effects of starting material, heat treatment and surface finishing are substantively discussed. An assessment of the current status of AM corrosion research, scientific gaps and research needs with greatest impact for AM SS advancement and qualification is provided.

“…Nitriding improves the surface hardness and wear resistance of various steel materials, such as tool steels and stainless steels. Thermo-chemical diffusion treatments such as nitriding and carburizing processes alter the surface of austenitic stainless steels as a main group of these materials [3][4][5][6]. However, the investigators carry out nitriding merely at low temperatures using liquid, gas or plasma environments; the industry is being more interested in plasma nitriding over traditional gas and bath nitriding [7][8][9].…”

Silicon nitride compound deposited by plasma enhanced chemical vapor deposition (PECVD) on plasma nitrided stainless steel 316L using tetraethylorthosilicate (TEOS):H 2 :N 2 mixtures. Plasma nitriding is extensively used to improve the hardness and wear performance of steels. It is also known that silicon nitride compounds can have interesting properties, such as low friction coefficient, high hardness and wear resistance. Therefore the deposition processes were carried out at optimized gas compositions and temperatures in order to obtain a combination of the best mechanical and enhanced tribological properties. The composition and structure of the surface layers were characterized using XRD, Glancing angle X-ray diffraction (GAXRD), optical and EDX built in electron microscopy, Microhardness and pin-on-disc wear tests. The compound of α-Si 3 N 4 was found on the top surfaces of PECVD and plasma nitrided austenitic stainless steel 316 L. The nitride compounds were composed of Fe 2-3 N, Fe 4 N in addition to chromium nitride. PECVD treatments substantially improved the hardness and wear resistance of plasma nitrided SS 316 L and reduced the friction coefficient and wear rate of the samples. The investigation showed that the combination of PECVD of organosilicon compounds and plasma nitriding results in superior high hardness, low friction and high wear resistance of treated surfaces if compared to those of conventional plasma nitrided surfaces.
