Lezi zinkampani ziyaziwa ngobuchwepheshe bazo bokukhiqiza izingxenye zekhwalithi ephezulu ze-sintered kanye nezingxenye zezimboni ezihlukahlukene, ezihlanganisa ezezimoto, i-aerospace, zezokwelapha, nezimboni.

Iyini Ingxenye Ye-Sintered?

Ingxenye ene-sintered into eqinile eyakhiwe ngenqubo yokucwilisa, okubandakanya ukuhlanganisa nokushisisa izinto eziyimpuphu ngaphandle kokuzincibilikisa ngokugcwele. Nazi izici ezibalulekile zezingxenye ze-sintered:

Inqubo Yokwakheka

Izingxenye ezihlanganisiwe zidalwa ngokucindezela kuqala izinto eziyimpuphu (njengezinsimbi, izitsha zobumba, noma amapulasitiki) zibe yisimo esifiswayo bese kushisisa ifomu elicindezelwe libe izinga lokushisa elingaphansi kwendawo yalo yokuncibilika. Le nqubo ihlanganisa i-voids futhi ibangele into eminyene cishe engu-100%.

I-Bonding Mechanism

Ngesikhathi sokushisisa, izinhlayiya ku-powder ocindezelweyo zakha isibopho ndawonye ezindaweni zazo zokuxhumana, zenze inqwaba eqinile. Le nqubo iqinisekisa amandla nobuqotho bomkhiqizo wokugcina.

Izinto zokwakha

Izingxenye ezisikiwe zingenziwa ngezinto ezihlukahlukene, okuhlanganisa izinsimbi (njengensimbi, nickel, nethusi), izitsha zobumba, namapulasitiki. Impahla ngayinye inikeza izakhiwo ezihlukile ezifanele izinhlelo zokusebenza ezahlukene.

Izakhiwo

Inqubo ye-sintering ikhiqiza izingxenye ezinamandla amakhulu nobulukhuni. Izici zokugcina zengxenye zincike ezintweni ezifana nokwakheka kwezinto, izinga lokushisa le-sintering, nobude besikhathi.

Izinhlelo zokusebenza

Izingxenye ze-Sintered zisetshenziswa ezimbonini eziningi, kufaka phakathi ezezimoto, i-aerospace, ne-electronics. Ziwusizo ikakhulukazi ekudaleni izimo eziyinkimbinkimbi nezingxenye ezinamaphoyinti aphezulu okuncibilika.

Izinzuzo

I-Sintering ivumela ukukhiqizwa kwezingxenye ezinobukhulu obunembile, ijometri eyinkimbinkimbi, kanye ne-porosity elawulwayo. Iphinde ingabizi kakhulu ekukhiqizeni ngezinga elikhulu izingxenye ezincane, eziyinkimbinkimbi.

Ngemuva kokucubungula

Ngemuva kokucwiliswa, izingxenye zingase zithole ukwelashwa okwengeziwe njengokusebenza ngomshini noma ukushisisa ukuze kuzuzwe izici ezifiselekayo zokugcina.

Empeleni, ingxenye ye-sintered iyinto eqinile eyenziwe ngezinto eziyimpuphu ngokusebenzisa inqubo yokushisa elawulwayo, okuholela engxenyeni eqinile, eminyene efaneleka izinhlelo zokusebenza ezihlukahlukene zezimboni.

Izingxenye Ezihlanganisiwe

Iyini Inqubo Yokukhiqiza Izingxenye Ze-Sintered?

Inqubo yokukhiqiza izingxenye ezisikiwe ngokuvamile ibandakanya lezi zinyathelo ezibalulekile ezilandelayo:

Ukwakhiwa Kwempushana

Izimpushana zensimbi ezifanele kanye nanoma yiziphi izithasiselo ziyakhethwa futhi zixutshwe ukuze kuzuzwe izakhiwo zezinto ezibonakalayo ezifiselekayo engxenyeni yokugcina.

Ukucinana

Ingxube yempushana icindezelwa ibe yisimo esifunwayo kusetshenziswa isikhunta noma ukufa, ngokuvamile ngaphansi kwengcindezi ephezulu. Lokhu kwakha ingxenye "eluhlaza" ebambe umumo wayo kodwa engakaqini ngokugcwele.

I-Sintering

Ingxenye eluhlaza iyashiswa esithandweni somoya esilawulwayo ukuze sibe nezinga lokushisa elingaphansi kwendawo yokuncibilika yensimbi eyinhloko. Lokhu kubangela ukuthi izinhlayiya zempushana zihlangane ndawonye, ​​zenze inqwaba eqinile.

Ukupholisa

Ngemuva kokucwiliswa, izingxenye zipholiswa ngendlela elawulwayo ukuze zigcine ubuqotho bazo besakhiwo.

Imisebenzi yesibili (uma kudingeka)

Ukucutshungulwa okwengeziwe kungenziwa, njengokusebenza ngomshini, ukwelashwa kokushisa, noma ukuqedwa kwendawo, ukuze kuzuzwe ukucaciswa kokugcina.

Izici ezibalulekile zenqubo ye-Sintering zihlanganisa:

• Ukulawula izinga lokushisa: Izinga lokushisa le-sintering lilawulwa ngokucophelela, ngokuvamile lifinyelela ku-1429°C ezingxenyeni zensimbi.
• Ukulawula Umkhathi: Isimo se-sintering silawulwa ngokucophelela ukuze kuqinisekiswe ukuhlangana okufanele futhi kuvimbele ukugeleza kwe-oxidation.
• Ukuminyana Kwenyuka: Ngesikhathi sokucwilisa, ukuminyana kwengxenye kuyanda njengoba i-voids phakathi kwezinhlayiya isuswa, okuholela ekutheni kube into eminyene engu-100%.
• Ukuthuthukiswa Kwezakhiwo: Inqubo ye-sintering ithuthukisa izakhiwo zokugcina zemishini nezomzimba zengxenye.

Le ndlela yokukhiqiza ivumela ukukhiqizwa kobunjwa obuyinkimbinkimbi ngokunemba okuphezulu futhi kubiza kakhulu ukukhiqizwa okukhulu kwezingxenye ezincane, eziyinkimbinkimbi. Isetshenziswa kabanzi ezimbonini ezahlukahlukene, kanti izimoto ziyindawo esetshenziswa kakhulu.

Izingxenye Ezihlanganisiwe

Isiphetho

Ukukhetha umkhiqizi wezingxenye ze-sintered ezifanele kubalulekile ukuze uqinisekise ikhwalithi nokuthembeka kwemikhiqizo yakho. Abakhiqizi abayi-10 abaphezulu abasohlwini lwalesi sihloko bafakazele ubuchwepheshe babo nokuzibophezela ekuletheni izingxenye ezisezingeni eliphakeme ezifakiwe kuzo zonke izimboni ezahlukahlukene. Ukuqonda ubunkimbinkimbi bezingxenye ezisikiwe kanye nenqubo yazo yokukhiqiza kungakusiza wenze izinqumo ezinolwazi futhi ukhethe uzakwethu ongcono kakhulu ngezidingo zakho. Kungakhathaliseki ukuthi udinga izingxenye zezimoto, i-aerospace, noma izinhlelo zokusebenza zezimboni, laba bakhiqizi banikeza ubuchwepheshe, ulwazi, nokuqinisekiswa kwekhwalithi edingekayo ukuze kuhlangatshezwane nezicaciso zakho.
