This paper presents a comparison of the deformations and residual stresses in gear wheels after vacuum carburizing process with quenching in high-pressure nitrogen and oil. The comparison was made on a medium-sized gear wheels, made of AMS6265 (AISI 9310) steel. This steel is applied in the aerospace industry for gears. The study has provided grounds for an assessment of the effect of the method of quenching on the size of deformations. Compared to oil quenching, high-pressure gas quenching following vacuum carburizing resulted in more uniform and smaller deformations.

“…Most especially, the sc-HSMG exhibited a susceptibility to reversible gas sorption, including selective sorption of hydrogen from the Ar -H 2 gas mixture. We commend the sc-HSMG for further investigation into its application as a functional nanomaterial for future gas sensors [26][27][28][29][30][31][32] and/or efficient hydrogen storage systems [33][34][35][36][37][38][39].…”

Gas sorption conditions on the graphene surface, as well as their influence on graphene properties, play a significant role when applications are considered. The influence of temperature and pressure on electric properties of graphene were investigated and discussed within this work, which was conducted in order to determine the border values for the sorption and desorption process of hydrogen on the graphene surface. The temperature was changed within the range of 243-373 K. Two types of graphene were used for comparison: one of graphene synthesised by our own method using chemical vapour deposition (CVD) and one of high strength metallurgical graphene (HSMG) in both conducting (cHSMG) and semiconducting (scHSMG) varieties. The characteristics were determined under hydrogen atmosphere in a fitted apparatus under pressure. The overall target material relies on the hydrogen storage of a designed graphene-based composite [1,2].

“…However, despite their higher heat transfer coefficient, particularly that of hydrogen, neither gas is likely to be applied as a modern cooling agent in heat treatment. Helium is extremely expensive and requires costly and extensive recycling systems; while hydrogen, due to its high risk of explosion, poses a logistics problem -although attempts are being made to eliminate this, for example by storing hydrogen in hydrides [2,9,16].…”

One of the many advantages of low pressure carburizing (LPC) is that it can be combined with high-pressure gas quenching. This makes it possible to achieve workpieces with pure metallic surfaces, less distortion hardening, and, above all, it allows a more reliable and repeatable treatment than conventional oil quenching. This article presents a study of the distortion rate of workpieces carburized at low pressure then quenched in nitrogen at 1.4 MPa. By comparing the distortion which takes place during the carburizing stage only and the carburizing combined with post-carburizing heat treatment it will be possible to assess the distortion rate and its causes at the different stages of the heat treatment process.
