DP Ibyiciro bibiri

Umusaruro:

Ibyo bita duplex idafite ibyuma mubisubizo byayo bikomeye bya ferrite na austenite bihura buri gice, mubisanzwe ibitarimo nibirimo nabyo bigomba kugera kuri 30%.Kubijyanye na C nkeya, Cr ibirimo 18% kugeza 28%, Ni ibirimo 3% kugeza 10%.Ibyuma bimwe na bimwe birimo Mo, Cu, Nb, Ti, N nibindi bintu bivanga.

 

Ibyiza.

Icyuma gifite ibiranga ibyuma bya austenitis na ferritic,

1. ugereranije na ferrite, plastike, ubukana burenze, nta bushyuhe bwicyumba cyo mucyumba, kurwanya ruswa yangirika hagati yimikorere no gusudira byateye imbere kuburyo bugaragara, mugihe nanone bikomeza ibyuma byujuje ibyuma bitagira umuyonga 475 ℃ ubwitonzi nubushyuhe bwinshi, hamwe nubushuhe nibindi nibindi.

2. Ugereranije nicyuma cya austenitike kitagira umuyonga, imbaraga nyinshi no kurwanya kwangirika kwimitsi no kurwanya ruswa ya chloride byateye imbere cyane.

3. Duplex idafite ibyuma idafite imbaraga zo kurwanya ruswa, ariko kandi igice cyicyuma cya nikel.
