Urupapuro rwibikoresho 17-4PH
Ibibanza
Ibikoresho bitagira umwanda 17-4 PH irangwa nimbaraga nyinshi zitanga umusaruro, kurwanya ruswa neza no kwihanganira kwambara cyane. 17-4 PH nimwe mubyuma byingenzi bishobora gukomera. Nisesengura ni kimwe nibikoresho 1.4548 na 1.4542.
Gukoresha mubushyuhe buke burashoboka hamwe na H1150 na H1025. Imbaraga zidasanzwe zagaragaye nazo zitangwa ku bushyuhe bukabije.
Bitewe nuburyo bwiza bwo gukanika no kurwanya ruswa, ibikoresho birakwiriye gukoreshwa mubidukikije byo mu nyanja, ariko birashobora kwangirika kwangirika mumazi yinyanja ahagaze.
17-4PH izwi cyane nka AISI 630.
Ibikoresho 17-4PH bikoreshwa mu nganda zikora imiti, inganda z’ibiti, umurenge wo mu nyanja, mu bwubatsi bw’ubwato, mu buhanga bw’imashini, mu nganda za peteroli, mu mpapuro, mu nganda za siporo. Inganda zo kwidagadura kandi nka verisiyo yongeye gushonga (ESU) mu kirere no mu kirere.
Niba imiterere yubukanishi hamwe no kurwanya ruswa ya martensitike idahagije, irashobora gukoreshwa 17-4PH.

Ibyiza
Umutungo umwe udasanzwe wibikoresho 17-4 PH nuburyo bukwiranye nubushyuhe buke kandi birashoboka kugeza hafi. 315 ° C.
Guhimba:Guhimba ibikoresho bibera mu bushyuhe bwa 1180 ° C kugeza kuri 950 ° C. Kugirango habeho gutunganya ingano, gukonjesha ubushyuhe bwicyumba bikorwa n'umwuka.
Gusudira:Mbere yuko ibikoresho 17-4 PH bishobora gusudwa, bigomba kwitabwaho kumiterere yibikoresho fatizo. Muburyo butajegajega, umuringa uboneka mubikoresho. Ibi biteza imbere kutavunika.
Kugirango ubashe gukora gusudira uburyo bwiza bwo gusudira burasabwa. Inenge cyangwa gusudira inenge zirashobora gutuma habaho urwego. Ibyo bigomba kwirindwa. Kugira ngo wirinde ko havuka ibibazo, ibikoresho bigomba kongera gukemurwa kugirango bikemurwe hamwe no gusaza nyuma mugihe gito cyane nyuma yo gusudira.
Niba nta nyuma yubushyuhe bubaho, indangagaciro-tekinoloji muri weld hamwe na zone yibasiwe nubushyuhe kubintu fatizo birashobora kuba bitandukanye cyane.
Kurwanya ruswa:iyo imiterere ya mashini hamwe no kurwanya ruswa ya martensitike idahagije, 17-4 PH irakwiriye gukoreshwa mubidukikije byo mu nyanja. Ifite imiterere yimashini nziza cyane hamwe no kurwanya ruswa.
Mu mazi yo mu nyanja ahagaze, 17-4 PH irashobora kwangirika. Ibi bisaba uburinzi bwinyongera.
Imashini:17-4 PH irashobora gutunganywa muburyo bukomeye kandi bukemurwa. Ukurikije ubukana, machinability iratandukanye, ibi bizaterwa nuburyo bimeze.
Kuvura ubushyuhe
Hagati ya 1020 ° C na 1050 ° C ibikoresho 17-4 PH ni igisubizo-gifatanye. Ibi bikurikirwa no gukonjesha byihuse - amazi, amavuta cyangwa umwuka. Ibi biterwa no guhuza ibice.
Kugirango uhindure byuzuye kuva austenite ujya kuri martensite, ibikoresho bigomba kuba bifite ubushobozi bwo gukonja mubushyuhe bwicyumba.

Ibyiza byo gukata
Gutunganya hamwe nicyuma ni uburyo bwo gutunganya ibikoresho, bivamo kugabanuka gukabije kutateganijwe no kongera ubukana kumiterere ihari, nko gukata amashyuza.
Rero, imashini yakozwe ifite imiterere imwe ndetse no kumpera, idahinduka mugukomeza ibikoresho.
Ibi bihe bituma kurangiza ako kanya igihangano hamwe no gusya cyangwa gucukura. Ntabwo rero ari ngombwa guhuza ibikoresho cyangwa gukora ibikorwa bisa mbere.
