Properties of Surface Layers Processed by a New, High-Temperature Vacuum Carburizing Technology with Prenitriding - PreNitLPC®

Influence of laser alloying with boron and niobium on microstructure and properties of Nimonic 80A-alloy

“…However, some processes, widely used for steels such as case-hardening or diffusion carburizing [5,6], were not appropriate for Ni-based alloys because of the very low solubility of carbon in nickel [7]. While such a surface treatment as boriding [8][9][10][11][12][13][14][15][16][17][18][19], nitriding [20][21][22][23][24][25][26][27][28][29][30] as well as physical and chemical vapor deposition [31][32][33] increased the hardness and wear resistance of the considered superalloys.…”

The Effect of the Quenching Method on the Deformations Size of Gear Wheels after Vacuum Carburizing

“…They are currently implemented in specialized furnaces or universal ones, making possible, depending on the type, the cooling of components (including quenching) in oil baths or in a stream of gas under high pressure -usually nitrogen [1][2][3][4][5][6]. Both carburizing and nitriding are currently realized in a controlled manner that allows, using computer-aided design processes, accurate control of the morphology of the surface layer [2,3,7,8].…”

“…Carburizing finds a very wide application in case of gears and toothed elements [1,3,5,9]. Vacuum carburizing process is better than conventional carburizing due to its efficiency; it also has certain other advantages, such as: no internal oxidation, higher uniformity of the carburizing layers produced in the process, energy efficiency and environmental friendliness [1][2][3][4][5][6].…”

The Impact of Prenitriding on the Microstructure and Mechanical Properties of the Carburized Surface Layer in a Martensitic Stainless Steel

“…Kula et al only tried to increase the carburizing efficiency by adding nitrogen during the heating process of carburizing for a low‐alloy steel. [ 26–28 ] Nevertheless, the method is quite different from prenitriding method used in this study, and the high alloy content makes the nitriding of stainless steels more particularly than that of low‐alloy steels.…”
