Investigation of Distortion Behaviour of Machine Components Due to Carburizing and Quenching
Original language description
Machine components (gear wheels and pinions) made from low-carbon structural steel 18CrNiMo7-6 were gas carburized to a standard case depth of 0.7 mm, nitrogen gas- or oil - quenched and tempered to a resulting surface hardness of 60 HRC. The dimensional(shrinkage, growth)- and shape distortion (out-of-roundness, out-of-flatness, teething deviations in transversal as well as longitudinal direction), caused by these treatment methods were measured. Also the positional effect in the test batch on the distortion and core hardness was assessed, in order to make a relationship between these parameters and to make a possibility to optimize the process in future. Finally, the distortion was correlated to the corer hardness as well as the CHD and the relationship between hardness and distortion was established.

Výzkum deformačního chování dílů v důsledku cementace a kalení
Czech description
Strojní díly (ozubená kola a pastorky) vyrobené z oceli 18CrNiMo7-6 byly cementovány v plynu ma houbku vrstvy 0.7 mm, kaleny dusíkem anebo v oleji a popuštěny na výslednou tvrdost 60 HRC. Změny rozměru a tvaru v důsledku tohoto tepelného zpracování bylyanalyzovány. Dále byl vyhodnocen viv uložení dílů na přípravku na deformace a stejně tak vliv tvrdosti jádra.
