Übersetzung für "Plasma nitriding" in Deutsch

For instance, there are known methods for plasma carburizing, plasma nitriding or plasma coating of metals.

The thin second oxide layer is then likewise subjected to plasma nitriding.

Carborating, oxide nitriding, plasma oxidizing and plasma carborating can be used as further methods.

This may be performed for example by gas nitriding, plasma nitriding or pressure nitriding.

Plasma nitriding with BALITHERM IONIT involves diffusing nitrogen 0.2 millimeters into the steel.

The layer composition of the surface layer O after the plasma nitriding corresponds to the layer composition with gas nitriding already illustrated.

For highly loaded components such as gears, plasma nitriding is the best solution.

By the use of hardening processes such as, for example, plasma-nitriding, gas-nitriding or carbureting, by which the surface structure on the armature 27 and/or core 2 is altered, it is even possible to completely relinquish direct coating procedures.

Useful for this are the known processes, such as finishing of the shaft by means of one or several finishing methods selected from the group comprising nitrocarbonizing, plasma-nitriding, treating with boron, laser hardening, hardening without carbonizing, induction hardening, flame hardening, electron-beam hardening, case hardening.

The plasma nitriding has the effect that nitrogen atoms are incorporated in the first oxide layer 4 outside the mask structure 6 in a region near the surface.

In order to refine a method for electric heating of furnaces for heat treating metallic workpieces, especially vacuum furnaces usable for plasma carburizing or nitriding, in which the heater elements of a furnace are supplied with a heating voltage that is generated in the secondary circuit of a three phase transformer connected to the three phase power network such that a comparatively small reactive power component can be obtained in a simple and economical manner, it is proposed that the primary coil windings of the three phase transformer be switched in the delta connection during a first heating phase and in the star connection during a second heating phase, whereby the switchover time from the delta connection to the star connection is determined as a function of operating parameters characteristic for the heating process.

The invention concerns a method for electrical heating of furnaces for heat treatment of metallic workpieces, especially for vacuum furnaces usable for plasma carburizing or nitriding, where the heating elements of the furnace are supplied with a heating voltage that is generated on the secondary circuit of a three phase transformer connected to a three phase network.

In order to avoid ionization of the furnace atmosphere in the area of the heating elements during plasma carburizing or nitriding, known furnaces are provided with heating elements that have low ohmic resistance and are supplied with a low heating voltage.

Above all, in connection with plasma carburizing or plasma nitriding, the latter leads moreover to avoiding ionization in the furnace atmosphere in the region of the heating elements.

Suitable as hardening processes for this purpose are, for example, the known nitride processes such as plasma nitriding or gas nitriding or carbureting.

The surface friction drag can be reduced by plasma-nitriding the friction surfaces, whereby at the same time the requirements for a reliable protection against rust are met.

The die according to any one of claims 1 to 4, wherein the die is surface-treated by means of plasma nitriding.

In the case of these cited low-temperature processes (nitriding and plasma-nitriding) for the indicated steels in the temperature range up to at most 595° C., in fact nitrogen diffuses into the steel surface but no phase conversion/austenitising takes place.

Oerlikon Balzers’ proven ability to replicate successful market penetration is a key enabler for acceleration of the thermal spray and plasma nitriding services and rapid geographic expansion – especially in emerging markets.

By means of the subsequent after-treatment by means of carbonizing, carbonitriding, case hardening, gas nitriding, oxide nitriding, gas nitro carburizing, plasma nitriding, plasma oxidizing, borating, plasma carborating or plasma borating, these advantageous properties are improved further.
