Yini na ukuba ihlabe lentsimbi lingagungqi libuye?

Abantu bahlala becinga loo ntoivalveyentsimbi engenasimo kwaye ayiyi kuba yingca. Ukuba iyakwenza oko, inokuba yingxaki ngentsimbi. Le yimbono ephosakeleyo ngobunye malunga nokungaqondi kwentsimbi engenasimo, enokuqhubela phambili phantsi kweemeko ezithile.

Intsimbi engenasimo inamandla okumelana ne-oxidation-Oko kukuthi, ukumelana nokunganyangeki, kwaye kukwazi ukulungisa kwimithombo yeendaba equkethe i-acids, ialkalis, kunye neetyuwa-Oko kukuthi, ukumelana nokucoca. Nangona kunjalo, ubungakanani bokukhula kwayo ukungavisisani kutshintshiwe kukwenziwa kwekhemikhali kwentsimbi yayo, imeko yokhuseleko, iimeko zokusetyenziswa kunye nohlobo lweendaba zokusingqongileyo.

Intsimbi engenasimo idlahlulwe yahlulwa ngokwahlukeneyo:

Ngokwesiqhelo, ngokwesistim ye-thlograc, intsimbi engenasiseko yahlulahlulwe yangamacandelo amathathu: i-austititic yentsimbi, i-ferric staic, i-ferric steen kunye nentsimbi engenasicabala. Kwisiseko sesithathu sezakhiwo ezisisiseko ze-feellographic, kwiimfuno ezithile neenjongo ezithile, izigaba ezibini zenqanaba, ukuxhoma izitho zibe zizinto ezingenasitali kunye nezixhobo eziphezulu ezinomxholo ongaphantsi kwe-50% zithathwe.

1. Intsimbi engenasitayile engenasibala.

I-matrix ilawulwa yi-Austedite yesakhiwo (isigaba se-CAD) sotywala obujolise kubuso, ongesozibuthelo, kwaye somelezwa ikakhulu kukusebenza kubanda (kwaye kunokukhokelela kwi-magnetic) intsimbi ethile. Iziko le-Iron kunye ne-SEEL lichongiwe ngamaNqaku kwiinguqu zochungechunge lwama-200 no-300, ezinjengama-304.

I-2. Intsimbi engenasimo ingenasinga.

Imatrix yile ilawulwa sisimo se-ferrite ((isigaba) sesakhiwo sekristali esigxile kwi-cuige, esingenakuphawuleka ngokuphathwa gadalala, kodwa somelezwe kancinci ngokusebenza kwe-430 nelama-436.

I-3. Mayeza intsimbi engenasibala.

I-Matrix yisakhiwo se-martix (i-cubic egxile emzimbeni okanye i-cubic), i-magnetic, kunye neepropathi zayo zinokuhlengahlengiswa ngonyango lobushushu. IZiko le-American American kunye ne-SEEL lonyulwa ngamanani angama-410, 420 kunye ne-440. UMartenite unesakhiwo esinamaqondo aphezulu, kwaye xa uguqulwa kwi-Marterite (It, ilukhuni).

I-4. I-Austetitic-Ferric (i-Deppex) intsimbi engenasibala.

I-matrix inama-Austerite kunye ne-Ferrite yeSiseko seSiseko seSiseko seSiseko seSithuba seSithuba seSigaba esiPhakathi, kwaye i-matrix encinci i-matrix ngokubanzi inkulu kune-15%. I-magnetic kwaye inokomelezwa kukusebenza kubandayo. 329 yintsimbi eqhelekileyo yenqwaba. Xa kuthelekiswa nentsimbi engenasitayile engenasiseko, intsimbi yesibini inamandla aphezulu, kwaye ukuxhathisa kwi-interrasion yosulelo kunye ne-chloride yoxinzelelo kukuphuculwa kakhulu.

I-5. Ukulinganisa ukulimaza intsimbi engenasibala.

I-matrix i-austedite okanye isakhiwo seMartiatic kwaye sinokukhula ngokuqina. IZiko le-American kunye ne-SEEL liphawulwa ngenombolo yama-600 yenguqulo, njengo-630, eyi-17-4ph.

Ngokubanzi, ukongeza kuma-Alloys, ukumelana ne-corrosion yentsimbi engenasimo ilungileyo. Kwindawo encinci yokungakhathali, i-Ferricc Staic Staines inokusetyenziswa. Kwindawo enobulali obuthathaka, ukuba loo nto kufuneka ukuba iphakame kakhulu okanye ubunzima obukhulu, i-martiaticic staines yentsimbi kunye nentsimbi eyenzakaliswa yintsimbi engenasitali.
