Surface Combustion introduces a new Vacuum Carburizing Technology

Surface Combustion introduces a new vacuum carburizing technology, which will be commercially known as VringCARBTM.

The new vacuum carburizing process is performed at low pressure in a vacuum furnace using a high-purity napthene hydrocarbon as the carburizing compound. The carburizing compound is supplied in a liquid form to fuel injectors producing a vapor dispersion around the work, that results in uniform carburizing. The injector system provides precise metering of the carburizing compound into the furnace. The furnace is designed to be inert with respect to the napthene so cracking of the gas occurs only at the workpiece, minimizing carbon deposits. A wide range of test results processed in both oil quench and high pressure quench designs have yielded consistent and predictable results. Patent applications for the technology were filed in July 2002.
