Uniform nitride film and oxynitride film are formed by low-temperature and high-speed nitriding, not dependent on nitriding time and nitriding temperature of nitriding reaction.
Provided is a steel for nitriding, which has a reduced strength before nitriding and therefore exhibits improved machinability.
The type of nitriding can be freely selected.
Rabourdin has their own in-house nitriding line called GR nitriding.
This may be by nitriding, ferritic nitrocarburising or ion nitriding.
Methods of nitridation and selective oxidation are provided herein.
A fixed charge layer may be formed by plasma nitridation.
A plasma nitridation is performed on the first dielectric layer.
After this, an additional nitridation step (20) and anneal is performed.
A supplemental silicon oxide layer is then formed (106) over the exposed SiON sidewalls, followed by nitriding (107) and a post-nitridation anneal (108).
The surfaces of the die, including surfaces inside the extrusion holes, are hardened by gas nitriding or plasma nitriding.
Proposed is a nitriding method characterized in that nitriding is conducted using a plasma which contains nitrogen atoms.
Provided is a steel sheet for soft nitriding which is excellent in terms of formability and strength stability after soft nitriding.
The friction surfaces (R) are after-treated by way of carboring, carbonitriding, case hardening, gas nitriding, oxide nitriding, gas nitro carburizing, plasma nitriding, plasma oxidizing, borating, plasma carborating or plasma borating.
The composition facilitates nitriding to heighten the surface hardness.
This steel for nitriding can be easily cut before nitriding, and is suitable for use as a material for a nitrided component such as a ring gear for automobiles.
Nitriding belongs to the thermochemical processes.
An electrode for glow discharging is arranged in the nitriding zone.
Prior art nitriding grade alloy steel generally have relied on molybdenum, nickel and other expensive alloy additions to provide nitridability and core hardness.
The surface treatment occurs preferably by means of nitridization and heat treatment.
nitriding is applied to obtain a solid nitrogen solution in the matrix %1F BTL
After this treatment, nitriding enables a further lowering in the brightness of black.
The nitriding and heat-treating may occur subsequently or simultaneously.
A steel strip is subjected to a nitriding treatment.
The surface of the guide is treated using nitriding, post-oxidation and micro-lubrication processes.
