Ukucinywa kunye nenkqubo yokufudumala ye-316L yentsimbi yentsimbi

Ukucima kunye nokufudumala ziinkqubo zokunyanga ukushisa ezisetyenziselwa ukuphucula iimpawu zomatshini wezinto eziphathekayo, kubandakanywa insimbi engenasici njenge-316L. Ezi nkqubo zihlala zisetyenziselwa ukomeleza ubulukhuni, ukomelela, kunye nokuqina ngelixa kugcinwa ukuxhathisa umhlwa. Nantsi indlela yokucima kunye nenkqubo yokufudumeza enokuthi isetyenziswe kwi-316L yentsimbi yentsimbi:

1. I-Anealing (Ngokuzikhethela): Ngaphambi kokucima kunye nokutshisa, unokukhetha ukukhupha i-316L yentsimbi engenasici ukukhulula uxinzelelo lwangaphakathi kunye nokuqinisekisa iipropati ezifanayo. I-Anealing ibandakanya ukufudumeza intsimbi kwiqondo elithile lobushushu (ngokuqhelekileyo malunga ne-1900 ° F okanye i-1040 ° C) kwaye emva koko uyipholise ngokucothayo ngendlela elawulwayo.
2. Ukucima: Fudumeza umcu wentsimbi engatyiwayo oyi-316L ukuya kubushushu bawo be-austenitic, ngokuqhelekileyo malunga ne-1850-2050 ° F (1010-1120 ° C) ngokuxhomekeke kwisakhiwo esithile.
   Bamba intsimbi kule qondo lokushisa ixesha elaneleyo lokuqinisekisa ukufudumeza okufanayo.
   Cima intsimbi ngokukhawuleza ngokuyintywilisela kwindawo yokucima, ngokuqhelekileyo ioli, amanzi, okanye isisombululo se-polymer. Ukukhethwa kwendawo yokucima kuxhomekeke kwiipropati ezifunwayo kunye nobukhulu bomgca.
   Ukucima ngokukhawuleza kuyipholisa intsimbi, ibangela ukuba iguquke ukusuka kwi-austenite ukuya kwisigaba esinzima, esine-brittle, ngokuqhelekileyo i-martensite.
3. Ukufudumala:Emva kokucima, intsimbi iya kuba nzima kakhulu kodwa ibe brittle. Ukuphucula ukuqina kunye nokunciphisa i-brittleness, intsimbi iyancipha.
   Ubushushu bobushushu bubalulekile kwaye ngokuqhelekileyo buphakathi kwe-300-1100 ° F (150-590 ° C), kuxhomekeke kwiipropati ezifunwayo. Ubushushu obuchanekileyo buxhomekeke kwisicelo esithile.
   Bamba intsimbi kwiqondo lokushisa lokushisa ixesha elithile, elinokuthi lihluke ngokusekelwe kwiipropati ezifunwayo.
   Inkqubo yokufudumala inciphisa ubunzima bentsimbi ngelixa iphucula ukuqina kwayo kunye ne-ductility. Okukhona ubushushu bobushushu buphezulu, kokukhona intsimbi iya kuba thambileyo kwaye idubule ngakumbi.
4. Ukupholisa: Emva kokupholisa, vumela umcu wentsimbi engatyiwa yi-316L uphole ngokwemvelo emoyeni okanye ngesantya esilawulwayo kwiqondo lobushushu begumbi.
5. Uvavanyo kunye noLawulo loMgangatho: Kubalulekile ukwenza iimvavanyo zoomatshini kunye nesinyithi kumcu ocinyiweyo kunye nobushushu ukuze uqinisekise ukuba uyahlangabezana neenkcukacha ezifunekayo kunye neempawu. Olu vavanyo lunokubandakanya uvavanyo lokuqina, uvavanyo lwe-tensile, uvavanyo lwempembelelo, kunye nohlalutyo lwe-microstructure. Iiparamitha ezithile zokucima kunye nobushushu, njengamaqondo obushushu kunye nobude, kufuneka zimiselwe ngokusekelwe kwiipropati ezifunekayo kwisicelo kwaye zinokufuna uvavanyo kunye novavanyo. Ukulawulwa ngokufanelekileyo kokufudumeza, ukubamba, ukucima, kunye neenkqubo zokufudumala kubalulekile ekufezekiseni ibhalansi efunekayo yobunzima, amandla, kunye nokuqina ngelixa ugcina ukuxhatshazwa kwe-corrosion kwi-316L yensimbi engenasici. Ukongezelela, amanyathelo okhuseleko kufuneka athathwe xa usebenza kunye neenkqubo zokushisa okuphezulu kunye nokucima okuphakathi.
