Insimbi Yensimbi Engagqwali

Incazelo emfushane:

Insimbi engagqwali yensimbi ingenziwa izingxenye. Amanzi ensimbi angenasici ancibilikisa esithandweni sokungeniswa ageleza aphume emgodini ovuzayo wombhobho, athomize ngamanzi acindezela kakhulu, futhi ajiyane ukuthola impuphu yensimbi engagqwali. I-powder ibiphelelwe amanzi emzimbeni, omisiwe, ahlanganisiwe futhi ananyisiwe, futhi ubukhulu bamanzi obuningi obungenawo insimbi engagqwali buyi-2.5 ~ 3.2g / cm.Ukwakhiwa ngaphansi kwengcindezi ka-550 ~ 830MPa.Ukuhlanganiswa kuhlanganiswe ku-hydrogen noma kumoya we-ammonia owonakele ngephuzu lamazolo -45 ~ -50 ℃ .I-sintering ye-vacuum nayo ingasetshenziswa, ukushisa kokushisa okungu-1120 ~ 1150 ℃ .Uma kudingeka izakhiwo ezinhle zomshini nokumelana nokugqwala, kusetshenziswa amazinga okushisa afinyelela ku-1315C.

Insimbi Yensimbi Engagqwali

Insimbi engagqwali yensimbi engenziwa ngensimbi ingenziwa insimbi.Amanzi ensimbi angenasici afakwa ku-powder nge-nitrogen ephezulu. Izinhlayiya ze-powder zazizindilinga, ukuminyana kokupakisha okuxekethile kwakucishe kube ngu-4.8g / cm, futhi okuqukethwe komoya-mpilo kwakungaphansi kuka-100 × 10. Ibhola lensimbi engagqwali ingaphinde ikhiqizwe ngokuzungezisa i-electrode pulverization nge-oxygen okuqukethwe (40 ~ I-70) × 10. Lezi powders zensimbi engagqwali zifakwa kukasi, kuvalwa i-vacuum, kubanda ukucindezela kwe-isostatic ekucindezelweni kwe-5kPa, bese kucindezela ukushisa oku-isostatic ku-1050 ℃ naku-2kPa ukucindezela okokusebenza. Ukuxinana okubandayo kwe-isostatic nakho kungashiswa kukhishwe zibe yizinduku ezihlanganayo namapayipi ku-1200 C .Iqhathaniswa nensimbi ejwayelekile neyakhiwe engagqwali, ukuhlukaniswa kwezinto ze-nickel, i-chromium ne-molybdenum kuzinsimbi ezingenazinsimbi ezenzelwe i-powder kuncane, usayizi wokusanhlamvu mncane kakhulu, futhi ukufakwa kwe-sulfide kulungile futhi ngokulinganayo Ngakho-ke kuyathuthukiswa:

1. Izinsimbi zensimbi ezingenasici eziyinsimbi

2. Izingxenye zensimbi engagqwali yensimbi

3. Izakhiwo zemishini nokumelana nokugqwala.

Izinsimbi ezikhethekile ezingenasici ezine-molybdenum ephezulu, i-nickel, i-nitrogen nokuqukethwe kwe-manganese zisetshenziselwa ukuqinisa ukumelana nokugqwala namandla ezindaweni ezinzima zasolwandle.
