14 lut 2023 · Here, we characterise the effects of time (up to 12 h) and temperature (490 to 560 ∘C) on nitridation with the aim to establish an effective regimen for the controlled synthesis of an aluminium nitride reinforcement powder for the production of metal matrix composites.
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, aluminium and molybdenum.
19 paź 2010 · Most treatment processes involve coating the surface of AlN particles with long chain organic molecules, such as carboxylic acids, particularly stearic acid, or through use of cetyl alcohol, n-decanoic acid, dodecylamine acid and so on (Egashira et al., 1991; Egashira et al., 1994).
18 lip 2013 · First a solution was prepared by dissolving reagents (aluminum nitrate, urea, and glucose) in water. Then the solution was heated in an electric furnace to 90 – 100°C. As a result of solution evaporation a gel-like mass was obtained.
This article provides information on the structure and properties of nitrided layers, and the technologies and mechanisms used for nitriding aluminum and its alloys. It also describes the nitriding behavior of aluminum alloys.
NITREG® is a modern heat-treating process, capable of meeting the metallurgical requirements of all nitriding specifications that may have been originally written for salt bath, plasma or traditional gas nitriding.
28 cze 2022 · Nitriding heat treatment is one of several surface hardening heat treat processes. Nitriding diffuses nitrogen into the surface of certain metals creating a hard surface more resistant to wear and corrosion.
