Ngaba Ngenene iStainless Steel Inamabhodlo?

Isishwankathelo
Intsimbi engatyiwa sisixhobo esithandwayo kumashishini ahlukeneyo, kuquka ukwakhiwa, iimoto, kunye ne-aerospace. Iipropathi zayo ezimelana nokumhlwa kunye nokuqina ziyenza ibe lolona khetho lubalaseleyo kwizicelo ezininzi. Nangona kunjalo, umbuzo omnye odla ngokuvela kukuba " ingaba intsimbi engenasici i-porous ". Impendulo echanekileyo kukuba, intsimbi eqhelekileyo engenasici ayinamabhodlo.
Kule posi yebhlog, siza kuphonononga isihloko se-porosity kwinsimbi engenasici kwaye sigqibe ukuba ingaba yinto enobungozi.

1. Yintoni iStainless Steel?

Okokuqala, kufuneka sazi ukuba yintoni insimbi engenasici?
Insimbi engenasici luhlobo lwentsimbi equkethe ubuncinane i-10.5% yechromium. Ezinye izinto, ezifana ne-nickel, i-molybdenum, kunye ne-titanium, nazo zisenokongezwa ukuphucula iimpawu zayo ezikwazi ukumelana nokuhlwa. Intsimbi estainless yaziwa ngokomelela kwayo okuphezulu, ukuqina, kunye nokuxhathisa ukubola, iyenza ilungele ukusetyenziswa kwiindawo ezirhabaxa.

Kodwa ngokuqinisekileyo, kukho iindidi ezininzi ezahlukeneyo zentsimbi engatyiwa, nganye ineempawu zayo ezizodwa kunye neempawu zayo. Okufana nentsimbi ye-Austenitic engenazibuthe, ayinamagnetic kwaye inokumelana nokugqwesa okugqwesileyo, ngelixa intsimbi engatyiwa yi-ferritic inomagnetic kwaye ayinyangeki kumhlwa.

2. I-Porosity kwizinto eziphathekayo

Emva koko kufuneka sazi ukuba yintoni iPorosity.
Ngamafutshane, iPorosity bubukho bezithuba ezingenanto okanye iipores ngaphakathi kwesixhobo. Izixhobo zePorous ziyakwazi ukufunxa ulwelo kunye neegesi, ezinokuchaphazela iipropati zabo kunye nokuqina. I-Porosity inokuba yinto yendalo kwezinye izinto, ezifana nemithi okanye isipontshi, okanye inokuba ngumphumo weenkqubo zokuvelisa, ezifana nokuphosa okanye ukuwelda.

Ubukho be-porosity bunokuchaphazela kakhulu iipropathi zoomatshini bezinto, njengamandla, i-ductility, kunye nokuqina. Izixhobo ze-Porous nazo zinokuthi zithandeke ngakumbi kwi-corrosion, njengoko ubukho be-voids bunokwenza iindlela ze-corrosive agents zingene kwizinto eziphathekayo.

3. I-Porosity kwi-Stainless Steel

Intsimbi engatyiwayo ingajika ibe manzi ngenxa yezinto ezininzi, kuquka iinkqubo zokwenziwa kakubi, ukuvezwa kwindawo ezonakalisayo, kunye nobukho bobumdaka. Uhlobo oluqhelekileyo lwe-porosity kwinsimbi engenasici yi-intergranular porosity, ebangelwa yimvula ye-carbides kwimida yeenkozo ngexesha le-welding.

I-Intergranular porosity inokunciphisa kakhulu ukuxhatshazwa kwe-corrosion yensimbi engenasici kwaye ichaphazele iimpawu zayo zomatshini. Ezinye iintlobo ze-porosity ezinokuthi zenzeke kwinsimbi engenasici ziquka i-hydrogen-induced porosity kunye ne-dendritic segregation.

4. Uvavanyo lwePorosity kwiStainless Steel

Kukho iindlela ezininzi zokuvavanya ubume bentsimbi engatyiwayo, kubandakanywa nokuhlolwa okubonakalayo, uvavanyo lokungena kwamanzi, kunye neradiyografi yeX-reyi. Ukuhlola okubonakalayo kubandakanya ukuphonononga ngokubonakalayo umphezulu wezinto eziphathekayo ngeempawu ze-porosity, ezifana ne-voids okanye iintanda. Uvavanyo lokungena kolwelo lubandakanya ukusebenzisa isisombululo sokungena kumphezulu wesixhobo kwaye emva koko usebenzisa umphuhlisi ukuveza naziphi na iziphene.

I-X-ray radiography yindlela yokuvavanya engonakalisiyo esebenzisa i-X-rays ukuvelisa imifanekiso yesakhiwo sangaphakathi sezinto eziphathekayo. Le ndlela iluncedo kakhulu ekuboneni i-porosity enokuthi ibekho ngaphantsi komphezulu wezinto eziphathekayo.

5. Ukusetyenziswa kwe-Non-Porous Stainless Steel

Non-porous steel stainless ibalulekile kumashishini aliqela, kuquka processing ukutya, amayeza, kunye nezixhobo zonyango. Umphezulu ongeyiyo intsimbi yentsimbi yenza kube lula ukucoca kunye nokucocwa, okwenza kube yinto efanelekileyo yokusetyenziswa kwiindawo apho ucoceko lubalulekile.

Insimbi engenasici nayo isetyenziswa ngokuqhelekileyo ekwakhiweni kweekhemikhali kunye nezityalo zepetrochemical, apho ibonakaliswe kwiindawo ezinobungozi ezinobungozi. Insimbi engena-porous stainless iyimfuneko kwezi zicelo zokuqinisekisa ukuba izinto eziphathekayo ziyakwazi ukumelana nokubola kwaye ziyakwazi ukumelana neemeko ezinzima.

Ukuqukumbela

Ukuqukumbela, intsimbi engenastainless inokuba yi-porous ngenxa yezinto ezininzi, kubandakanywa neenkqubo ezingekho phantsi kokwenziwa kwemveliso, ukuvezwa kwindawo ezonakalisayo, kunye nobukho bobumdaka. I-Porosity kwinsimbi engenasici inokunciphisa kakhulu ukuxhathisa ukubola kunye nokuchaphazela iimpawu zayo zomatshini.

I-Porosity inokunciphisa kakhulu ukuxhathisa kwe-corrosion yensimbi engenasici, okwenza kube lula ukubola. Kwakhona kunokunciphisa izinto eziphathekayo, ukunciphisa amandla kunye nokuqina kwayo.

4. Ifunyaniswa njani i-porosity kwintsimbi engenasici?

Ukuhlola okubonakalayo yindlela elula yokuvavanya i-porosity, kodwa isenokungasebenzi ekuboneni i-porosity ekhoyo ngaphantsi komphezulu wezinto eziphathekayo. Uvavanyo lokungena kolwelo kunye ne-X-reyi ye-radiography ziindlela ezisebenzayo ngakumbi zovavanyo lwe-porosity, njengoko zinokubona iziphene zomhlaba kunye ne-porosity ekhoyo phantsi komphezulu wezinto.

5. Ingaba yonke intsimbi engenazibonda ayinazimbobo?

Hayi, ayizizo zonke intsimbi engenazinyosi. Ezinye iintlobo zetsimbi ezingenasici zine-porous kunezinye, kuxhomekeke ekubunjweni kwazo kunye nenkqubo yokuvelisa. Ngokomzekelo, i-304 insimbi engenasici ngokuqhelekileyo ayinayo i-porous, ngelixa i-316 insimbi engenasici inokuchaphazeleka ngakumbi kwi-porosity ngenxa yomxholo wayo ophezulu we-molybdenum.

6. Ngawaphi amashishini axhomekeke kwintsimbi engenazimbobo?

Intsimbi engenazibonda ibalulekile kumashishini aliqela apho ucoceko kunye nokumelana nomhlwa zizinto ezibalulekileyo. La mashishini aquka ukulungisa ukutya, amayeza, kunye nezixhobo zonyango. Insimbi engenasici nayo isetyenziswa ngokuqhelekileyo ekwakhiweni kweekhemikhali kunye nezityalo zepetrochemical, apho ibonakaliswe kwiindawo ezinobungozi ezinobungozi.
