It consists of four independent horizontal tubes for deposition. Silicon nitride films were deposited at two temperatures 800, 850 °C with varying mixture of dichlorosilane (SiH 2 Cl 2) and ammonia (NH 3 ). The thickness and phase constitution of the resulting nitriding layers can be selected and the process optimized for the particular properties required. The advantages of gas nitriding over other variants are: Precise control of chemical potential of nitrogen in the nitriding atmosphere by controlling gas flow rate of nitrogen … Ver mais Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-alloy steels. They are also used on titanium Ver mais The processes are named after the medium used to donate. The three main methods used are: gas nitriding, salt bath nitriding, and plasma nitriding. Gas nitriding In gas nitriding the donor is a nitrogen-rich gas, usually Ver mais • Boriding • Carburization • Carbonitriding • Ferritic nitrocarburizing Ver mais • "MIL-S-6090A, Military Specification: Process for Steels Used In Aircraft Carburizing and Nitriding".
