Low-pressure carburizing systems: A review of current technology
BHM Berg- und Hüttenmännische Monatshefte, 2006Although the great majority of carburizing is still carried out at atmospheric pressure, recent developments in vacuum furnaces and steel technology have meant that carburizing can now be carried out in a more environmentally friendly way under low pressure.

Precision Case Hardening by Low Pressure Carburizing (LPC) for High Volume Production*
HTM - Journal of Heat Treatment and Materials, 2017 Traditionally, case hardening is based on carburizing in atmospheres and oil quenching; this is carried out in sealed quench furnaces and in continuous lines (pusher, roller or rotary furnaces).

Predictions of Carbon Fluxes During a Low Pressure Carburizing Treatment
Heat Transfer: Volume 6 — Heat Transfer in Materials Processing, 2001Abstract This paper presents the qualitative assessment of a novel device developed for the regulation of carburizing processes in industrial vacuum furnaces. The proposed device involves a U-shaped thin wall iron tube: the outside surface of the tube is exposed to the carburizing atmosphere simultaneously with the workload, while the ...

Heat Treating Conference, 2015
Abstract For more than 20 years now Low Pressure Vacuum Carburizing (LPC) has taken over several industries as the main carburizing choice. These industries take advantage of LPC’s clean environment, versatility, “just in time” processing, along with possible distortion control that comes with gas quenching capabilities to process ...

Low Pressure Carburizing Distortion Data Comparing Oil and High Pressure Gas Quenching
Heat Treating Conference, 2017Abstract This presentation will discuss data on parts tested in Low Pressure Carburizing using oil and gas quenching. We will present data on metallurgy, distortion and load design to optimize each quenching media. As we know oil and gas quench respond differently, we will explore the evolution of high pressure gas quenching as it exist ...

Vacuum Heat Treatment and Low Pressure Carburizing of APS NiCr Coatings
International Thermal Spray Conference, 1998Abstract Duplex processes consist in applying a treatment, like annealing, carburizing, or nitriding for example, to a plasma sprayed coating in order to improve particular physical characteristics of this coating. Trials of vacuum heat treatment or low pressure carburizing have been performed on APS NiCr coatings, previously sprayed on ...

Development of New Alloy Steel for High-Temperature Low Pressure Carburizing
SAE Technical Paper Series, 2002<div class="htmlview paragraph">Gas carburizing is a surface hardening method that is used for automobile steel parts such as gears. The conventional gas carburizing(at 1223K) takes longer time. Shortening the carburizing time will contribute greatly to the energy saving and CO<sub>2</sub> reduction of parts production.</div> ...
