Okwesibili, ukwakheka kwe-microstructure ye-nickel-based superalloy, okungukuthi, uhlobo, i-morphology, usayizi, okuqukethwe nokusatshalaliswa kwesigaba ngasinye, ikakhulukazi isigaba esinqanyuliwe, sinquma ukushisa okuphezulu kwempahla nokusebenza kwempilo yokusebenza. Kodwa-ke, ukwakheka okuncane kwe-alloy kunqunywa ukwakheka kwayo. Ngakho-ke, umthombo wokunquma ukusebenza kwe-alloy ulele engxenyeni ye-alloy uqobo, okungukuthi, uhlobo nokuqukethwe kwento ngayinye eyakha ingxenye ye-alloy. Ake sibheke ukwakheka kwe-INCONEL 625 alloy:

I-INCONEL 625 / UNS N06625 / DIN 2.4856

Lokhu ingxubevange has izici ezilandelayo:

• 1. Inokumelana okuhle nokugqwala kwimidiya eyahlukahlukene ebhubhisayo ezindaweni ezinamakhemikhali nokwehlisa izindawo
• 2. ukumelana Excellent pitting futhi crevice ukugqwala, futhi ngeke kuveze ukucindezeleka ukugqwala nokuqhekeka okubangelwa chloride
• 3. Ukugqwala okuhle kakhulu kuma-acid angaphili, njenge-nitric acid, i-phosphoric acid, i-sulfuric acid, i-hydrochloric acid kanye ne-acid exubile ye-sulfuric acid ne-hydrochloric acid,
• 4. Ukumelana okuhle kakhulu nokugqwala kwezixazululo ezahlukahlukene ezingxube ze-asidi
• 5. Lapho izinga lokushisa lifinyelela kuma-40 ℃, lingakhombisa ukumelana nokugqwala okuhle ezindaweni ezinhlobonhlobo zesisombululo se-hydrochloric acid
• 6.Ukusebenza okuhle nokuqina, akukho ukuzwela kokuqhekeka ngemuva kokushisela
• 7. Yenza isitifiketi sesitsha sengcindezi esinamazinga okushisa odonga phakathi kuka -196 ～ 450 ℃
• 8. Kuqinisekiswe yi-American Society of Corrosion Engineers standard ye-NACE (MR-01-75) ukuhlangabezana nezinga eliphakeme kakhulu le-VII lokusetshenziswa ezindaweni zegesi ene-asidi

● I-Inconel 625 isakhiwo se-metallographic

I-625 iyisakhiwo se-cubic lattice esibheke ebusweni. Lapho igcinwa cishe ku-650 ℃ isikhathi esanele ngokwanele, izinhlayiya zekhabhoni nesigaba esingazinzile se-quaternary sizongena siguqulwe sibe isigaba esizinzile se-Ni3 (Nb, Ti) orthorhombic lattice. Ngemuva kokuqiniswa kwesixazululo esiqinile, izingxenye ze-molybdenum ne-niobium ku-nickel-chromium matrix zizothuthukisa izakhiwo zomshini wento, kepha i-plasticity izoncishiswa.

● I-Inconel 625 ukumelana nokugqwala

I-alloy 625 ikhombisa ukumelana nokugqwala okuhle kakhulu kwabezindaba abaningi. It has ukumelana omuhle pitting ukugqwala, crevice ukugqwala, ukugqwala intergranular nokuguguleka e chloride abezindaba. It has ezinhle ukugqwala ukumelana acid wezinto, ezifana nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, njll. Ukumelana okusebenzayo kwe-chloride ion-ekunciphiseni ukucindezela kokugqwala. Cishe akukho ukugqwala emanzini olwandle nasezimbonini zegesi, futhi inokumelana okuphezulu nokugqwala kumanzi asolwandle kanye nezixazululo zikasawoti, ngisho nasezingeni eliphakeme lokushisa. Akukho ukuzwela ngesikhathi sokushisela. Iyamelana ne-carbonization ne-oxidation ezindaweni ezimile noma ezijikelezayo, futhi iyamelana nokugqwala ngamagesi aqukethe i-chlorine.

● Hlukanisa izindawo zezicelo ezingu-625

Ingxubevange ethambile futhi enamathiselwe ephansi engaphansi kwe-625 isetshenziswa kabanzi embonini yenqubo yamakhemikhali. Ukumelana nokugqwala kwayo okuhle namandla amakhulu kuyenza ibe yingxenye yesakhiwo esincanyana. Ingxubevange engu-625 ingasetshenziswa ezinhlelweni ezihlangana namanzi olwandle futhi ezimelana nokucindezela okukhulu kwemishini. Izindawo ezijwayelekile zohlelo lokusebenza:

• 1. Izingxenye zezinqubo zamakhemikhali eziqukethe i-chloride, ikakhulukazi lapho kusetshenziswa khona izinto zokuvikela i-acid chloride
• 2. Umgudu wokugaya ukudla nokhokhishela obusetshenziswa ekwakheni uginindela nephepha lemboni
• 3. Umbhoshongo wokumunca, ukushisa kabusha, ukudideka kokungena kwegesi, i-fan (emanzi), i-agitator, i-deflector, ne-flue ohlelweni lwe-flue gas desulfurization
• 4. Isetshenziselwa ukwenza imishini nezinto ezisetshenziselwa imvelo yegesi ene-asidi
• 5. I-Acetic acid ne-acetic anhydride reaction generator
• 6. Isithwesi se-sulfuric acid

Kutholakala ku-INCONEL 625 ukuthi kudingeka okuqukethwe okuphezulu kwezinto ezingxube i-oxidizable alloy ezifana ne-chromium, molybdenum, cobalt, titanium nezinye izinto eziqinisayo. La ma-alloys e-oxidizable element kanye nezinsimbi ze-nickel uqobo ziba yizinto ezibalulekile zokungcola okuyingozi ku-alloy, ikakhulukazi iSulfure ne-phosphorus Source, okuqukethwe kwezinto ezingcolisayo eziyingozi S no-P kuma-superalloys asuselwa ku-nickel kudingeka ukuthi abe ngaphansi kuka-0.010-0.020%.
---------------------------------------
Ngaphezu kwalokho, izindlela zokushisa ze-alloy eziphakeme kakhulu zifaka phakathi ukwakhiwa nokusakaza. Inqubo yokusakaza isebenzisa uketshezi lwe-superalloy engamanzi ukugcwalisa umgodi wesikhunta ukwakha umkhiqizo oyifunayo. UKWAKHA inqubo yezobuchwepheshe lapho ingxubevange eshisa kakhulu idlula khona-okushisa okushisayo okuphezulu okushisayo kwe-thermoplastic ukugcwalisa isikhunta, ngaleyo ndlela kwakheke umkhiqizo owuthandayo. Kokubili kunezinzuzo nezinkinga. Phakathi kwabo, ukusakaza kuhle ekwakheni izingxenye eziyinkimbinkimbi, futhi ukwakhiwa kusekelwe ekuthuthukiseni ukusebenza komkhiqizo.
---------------------------------------
Ekugcineni, ake sibheke ifomu lokunikezwa kwe-INCONEL 625 superalloy:

• Ukucaciswa kweshidi le-INCONEL 625: 0.5-60MM
• INCONEL 625 induku impahla Φ8-Φ200MM (black lesikhumba, induku ukukhanya)
• Inganikezwa kubude bekhasimende:
