Izinto ezili-10 ekufuneka uzazi ngentsimbi engenasici

Intsimbi engagqwaliyo iye yaba yenye yezona zinto zisetyenziswa kakhulu nezithembekileyo kuluntu lwanamhlanje. Ukususela kwizakhiwo ezinde kunye nemibhobho yemizi-mveliso ukuya kwizixhobo zotyando kunye nezixhobo zasekhitshini, intsimbi engagqwaliyo ikho kuyo yonke indawo. Ukuthandwa kwayo kuvela kudibaniso lwayo olulodwa lwamandla, ukuqina, kunye nokumelana nokugqwala kunye nokubola. Sekunjalo, abantu abaninzi bayazi intsimbi engagqwaliyo kuphela "njengesinyithi esikhazimlayo" ngaphandle kokuqonda iimpawu zayo ezinzulu.

Ukukunceda uqonde ukuba kutheni intsimbi engagqwaliyo ibaluleke kangaka, naziIzinto ezili-10 ekufuneka uzazi malunga nentsimbi engagqwaliyo.

1. Intsimbi Engagqwaliyo Yi-Alloy

Intsimbi engagqwaliyo ayisiyontsimbi icocekileyo. Yingxubevange eyenziwe ngentsimbi, ene-chromium njengeyona nto iphambili eyenza ukuba "ingabi nasici." Ngokwenkcazo, intsimbi engagqwaliyo kufuneka ibe ne-chromium eyi-10.5 ekhulwini ubuncinane. Ezinye izinto ezifana ne-nickel, i-molybdenum, i-titanium, okanye i-nitrogen zihlala zongezwa ukuphucula iimpawu ezithile ezifana nokuqina, ukumelana nokugqwala, okanye amandla.

2. Imfihlo Engasemva Kokumelana Nokugqwala

Ipropati "engenasicaba" ivela kwindalo, ebhityileyo, nengabonakaliyoumaleko we-chromium oxideokwenziwa phezu komphezulu wentsimbi engagqwaliyo. Le filimu ingasebenziyo isebenza njengekhaka, ithintela ioksijini kunye nokufuma ukuba kungangeni kwisinyithi kwaye kubangele umhlwa. Ukuba ikrwelwe, umaleko uyaziphilisa ngokwawo xa kukho ioksijini, ukuqinisekisa ukhuseleko oluqhubekayo.

3. Kukho iintlobo ezahlukeneyo zentsimbi engagqwaliyo

Intsimbi engagqwaliyo ayiyonto inye. Iza kwiintsapho ezahlukeneyo, nganye ineempawu zayo ezikhethekileyo:

• I-Austenitic: Eyona ixhaphakileyo, engenamagnethi, enganyangekiyo kakhulu kukugqwala, esetyenziswa ekulungisweni kokutya nasekwakheni izakhiwo.

• I-Ferritic: Imagnethi, ingabizi kakhulu, inokumelana nokugqwala okuhle, isetyenziswa rhoqo kwiimoto.

• I-Martensitic: Yomelele kwaye iqinile kodwa ayimelani nokugqwala, isetyenziswa rhoqo kwiimela nezixhobo.

• I-Duplex: Idibanisa izakhiwo ze-austenitic kunye ne-ferritic, inika amandla aphezulu kunye nokumelana okuhle kakhulu nokuqhekeka kwe-stress corrosion.

• Ukuna kwemvula-Ukuqina: Ifumana amandla aphezulu kakhulu ngonyango lobushushu, olusetyenziswa kwizicelo zeenqwelo-moya.

4. Intsimbi Engagqwaliyo Ingasetyenziswa Kwakhona

Enye yezona nzuzo zinkulu zentsimbi engagqwaliyo kukuzinza kwayo.Ingasetyenziswa kwakhona nge-100%ngaphandle kokulahlekelwa ngumgangatho. Ngaphezulu kwama-60 ekhulwini entsimbi entsha engagqwaliyo ivela kwizinto ezilahliweyo ezisetyenzisiweyo, nto leyo eyenza ukuba ibe lukhetho olunobuhlobo nokusingqongileyo kumashishini azama ukunciphisa impembelelo yokusingqongileyo.

5. Yafunyanwa Ngengozi

Ukufunyanwa kwentsimbi engagqwaliyo ngo-1913 nguHarry Brearley eSheffield, eNgilani, kwakungengozi. UBrearley wayezama ukusebenzisa i-alloys zentsimbi ukuphucula ukumelana neebharele zemipu xa wabona isampuli enye imelana nokugqwala. Oku kufunyaniswa kwabangela ukuphuhliswa kwentsimbi engagqwaliyo njengoko sisazi namhlanje.

6. Intsimbi Engagqwaliyo Inezicelo Ezingapheliyo

Ukuguquguquka kwentsimbi engagqwaliyo kuyenza ibe yintandokazi kuzo zonke iindawo:

• Uyilo lweZakhiwo kunye noKwakha: Iibhulorho, iifacade, uphahla, kunye neenkxaso zesakhiwo.

• Ukutya neZiselo: Izixhobo zokucubungula, iitanki, imibhobho, kunye nezixhobo.

• EzonyangoIzixhobo zotyando, izinto zokufakelwa, kunye nezixhobo zesibhedlele.

• Uthutho: Iinkqubo zokukhupha umoya kwiimoto, iindawo zeenqwelo-moya, kunye nokwakhiwa kweenqanawa.

• Amandla: Izikhululo zamandla enyukliya, amaqonga aselunxwemeni, kunye nezakhiwo zamandla avuselelekayo.

Ukudibana kwayo nokuqina, ukumelana nokugqwala, kunye nococeko kuqinisekisa ukusetyenziswa kwayo ngokubanzi.

7. Intsimbi Engagqwaliyo Kulula Ukuyicoca

Umphezulu wentsimbi engagqwaliyo, ongenamibhobho, wenza kube lula ukuwucoca nokuyigcina icocekile. Yiyo loo nto ithandwa kakhulu kwimizi-mveliso yokulungisa ukutya, ezempilo, kunye namayeza apho ucoceko lubaluleke kakhulu. Ukucoca rhoqo ngeesepha ezithambileyo kugcina imiphezulu yentsimbi engagqwaliyo ikwimeko entle ngaphandle kokonakalisa umaleko we-oxide okhuselayo.

8. Iyakwazi Ukumelana Nobushushu Obugqithisileyo

Intsimbi engagqwaliyo isebenza kakuhle xa kushushu kakhulu kwaye kubanda kakhulu.

• Amanqanaba obushushu aphezulu agcina amandla kwaye ayamelana nokungcoliswa kwi-oven okanye kwizityalo zamandla.

• Amanqanaba obushushu obuphantsi ahlala enzima kwiindlela ezisetyenziswayo ezifana nokugcinwa kwegesi yendalo.

Olu buchule bokumelana nobushushu obugqithisileyo lwenza intsimbi engagqwaliyo ibaluleke kakhulu kumashishini abalulekileyo.

9. Ukugqitywa komphezulu kongeza okungaphezulu nje kobuhle

Intsimbi engagqwaliyo ifumaneka kwiintlobo ngeentlobo zeengubo zomphezulu, ukusuka kwi-polished-glass ukuya kwi-matte okanye ibrashi. Ezi ngubo zomphezulu azipheleli nje ekubukekeni—zikwachaphazela nokusebenza kakuhle. Iingubo zomphezulu ezipholisiweyo kulula ukuzicoca kwaye ziyamelana nokukhula kweebhaktheriya, ngelixa iingubo zomphezulu ezipholisiweyo zifihla iminwe kunye nemikrwelo kwiindawo ezinabantu abaninzi. Iingubo zomphezulu zivumela intsimbi engagqwaliyo ukuba ilinganisele umsebenzi kunye nomtsalane woyilo.

10. Ukukhetha iBanga elifanelekileyo kubalulekile

Ayizizo zonke iintsimbi ezingenasici ezilinganayo. Udidi olufanelekileyo kufuneka lukhethwe ngokuxhomekeke kwisicelo:

• 304 Intsimbi Engagqwaliyo: Eyona ixhaphakileyo, ifanelekile ekusetyenzisweni kokutya neziselo.

• 316 Intsimbi Engagqwaliyo: Iqulethe i-molybdenum yokuqinisa ukumelana nezifo zaselwandle okanye kwiindawo ezineekhemikhali.

• Intsimbi Engagqwaliyo engama-430Uhlobo lwe-ferritic olusetyenziswa kakhulu kwiindlela zokuhombisa kunye neemoto.

• Intsimbi Engagqwaliyo Ephindwe Kabini 2205: Isetyenziswa kumashishini angaphandle nangaphandle kweekhemikhali ukuze ikwazi ukumelana nokugqwala ngamandla aphezulu kunye noxinzelelo.

Ukukhetha umgangatho ochanekileyo kuqinisekisa ukuqina, ukhuseleko, kunye nokusebenza kakuhle kweendleko.

Iingcebiso Zokugcina Nokunyamekela

Nangona intsimbi engagqwaliyo imelana kakhulu nokugqwala, isafuna ukulungiswa ngokufanelekileyo:
