Abstract
A method of low pressure carburizing (LPC) of elements made of iron alloys and of other metals in a device for continuous, in-line thermochemical surface treatment, with a constant time-step, with saturation at a temperature from 820° C. to 1200° C. in gaseous atmosphere, wherein into the vacuum chamber of the device a gaseous carbon carrier is introduced using impulses in a constant flow-time sequence, synchronized with the working time-step of the device.
