atmospheric carburizing
atmospheric carburizing

Atmospheric carburising Carburising is a case hardening process that introduces carbon into a solid ferrous alloy. This is accomplished by heating the metal in a carbonaceous atmosphere above transformation temperature for a pre-determined ...

LPC

Low pressure carburising (LPC) LPC is a case hardening process carried out in a vacuum furnace using hydrocarbon gases at very low pressure and elevated temperatures to obtain a hardened surface layer of tempered martensite and a tough ...

automotive carbonitriding

Carbonitriding Carbonitriding is an austenitic (above A3) case hardening process similar to carburising, with the addition of nitrogen (via NH3 gas), used to increase wear resistance and surface hardness through the creation of a hardened ...

ARCOR DT

The ARCOR DT treatment was specially developed for the low-temperature nitriding of engine valves. Since the treatment temperatures can vary between 490°C and 530°, it is therefore easy to nitride engine valves (made of martensitic ...
