Ndiyenera kuchita chiyani ngati ng’anjo ya vacuum annealing kwambiri oxidized?

Mu ng’anjo ya vacuum annealing, chingwe chamkuwa chimakhala ndi oxidized, kusonyeza kuti ng’anjo ya vacuum ikudontha.

1. Yang’anani ngati vacuum yogwira ntchito ya vacuum pump ndi yabwinobwino. Gwiritsani ntchito vacuum gauge kuti muone ngati pali vacuum polowera polowera kuti muone ngati ingafike pomaliza pake. Ngati sichoncho, sinthani mafuta, kapena konzani, ndipo musasinthe mpope.

2. Gwiritsani ntchito chotolera chotupitsa kuti munyamule kudontha kwa ng’anjo ya vacuum. Ngati palibe chodziwira chotsikirira (chodziwikiratu chotsikirapo ndichokwera mtengo kwambiri), gwiritsani ntchito acetone (mowa wa m’mafakitale) kuti mutenge kudonthako, mulingo wodziwika bwino ndi 0.2Pa/h, pasakhale vuto.
