At the time of thermochemical finishing manner in order the aural masking to do the component, the device and the excavation component

摘要

(57) Abstract This invention, manner in order the aural masking to do the excavation component, regards the device and the excavation component at the time of thermochemical finishing. It seems like the excavation tube or the excavation stick, the excavation component for placing excavation (1), same as the median channel for the media which flows at least has with the basic forma where 1 free destals (2) and the said component is extended substantially. The part which possesses the depth (d) and of the 1st surface is hardened (4), is formed to the jacket surface of the component at least partly. The part which is not hardened, is formed at least partly in the said free destal (2), in that case, the movement area which is the longitudinal direction between the material which is hardened and the material which is not hardened (6) has 1st length (b). Movement area (6) 1st length (b), 1st is longer than depth (d) of the surface.
