Iimpawu ze-welding zensimbi ye-austetitic ye-austetitic egqwesileyo: Uxinzelelo lwe-elastic kunye neplastiki kunye netrasti ngexesha lenkqubo ye-welding inkulu kakhulu, kodwa kunqabile ukubonwa. Akukho ndawo yokuhamba egudileyo kunye nengqolowa ebalekayo kwi-SIDL, ngoko ke amandla e-sunsle ye-weld iphezulu.
Ezona ngxaki ziphambili ze-austitic yensimbi ye-welding yensimbi yentsimbi: Ngenxa yemida yobukumkani bokuzibhokoxa kunye neemvakalelo zokungcola okuthile (s, p), kulula ukuvelisa imifuno eshushu.
Iingxaki ezintlanu eziphambili ze-welding kunye namanyathelo onyango lwensimbi ye-austetitic
I-01 Ukusekwa kwe-Chromium Carbide kunciphisa ubuchule be-weld ukuba ukuxhathisa i-insosion ye-Intergranure.
I-Trasion yoThengiso phakathi: Ngokomlomo we-chromium, i-chromium ye-chromium ye-chromium kwimida yobushushu ye-450-850 ℃, oko kungonelanga ukuxhathisa ukhuphelo.
.
a. Ukunciphisa umxholo wekhabhoni wensimbi yesiseko kunye ne-weld, kwaye wongeza izinto zokuzinzisa i-TI, i-NB kunye nezinye izinto kwinsimbi yesiseko ukunqanda ukwenziwa kwe-MC23C6.
b. Yenza ukuba i-WALD yenze ubume besigaba sendawo ye-austedite kunye nenani elincinci lezinto ezifundwayo. Xa kukho inani elithile lezinto ezifudumeleyo kwi-WRED, iingqolowa zinokuhlaziywa, indawo yokudla okuziinkozo zinokunyuswa, kunye nokuthambisa kwe-chromium carbide kwicandelo ngalinye lomda wengqolowa unokuncitshiswa.
I-chromium inyibilikiswe kakhulu kwi-FRET. I-CRR23C6 ikhethekile ngokunyaniseka ngaphandle kokuzibhokoxa kwemida yokudla okuziinkozo eziza kupheliswa kwiChromium; Ukusasazeka phakathi kwama-Austedites kunokuthintela ukohlwaya umda kumda wokudla okuziinkozo kwilizwe langaphakathi.
c. Lawula ixesha lokuhlala kuluhlu lobushushu bemvakalelo. Lungisa umjikelo we-werrm wel, qinisa ixesha lokuhlala elinama-600 ~ 1000 ℃ ngokusemandleni e-Degon of Gedwork, kwaye usebenzise i-Argon Argon Argan okanye usebenzise i-Argon Ged, kwaye unciphise amaxesha okuphepha ukufudumeza, kunye nomfowunelwa Umphezulu ophakathi ophakathi kwe-corrosing ngexesha le-weldiayer ye-Multilayer kufuneka ibe yeyokwenziwe ngexesha elifanelekileyo.
d. Emva kokwenza i-welding, yenza uzinzo lwesisombululo okanye uzinzo lube nokuthintela (850 ~ 900 ℃) kunye nomoya ukuphola ukwenza ukuba i-carbide ikhuphe kwaye ikhawuleze i-chromium).
. Ngesi sizathu, amanyathelo okhuseleko alandelayo anokuthathwa:
Ngenxa yokwazi okungaqhelekanga kwekhabhoni, kuya kudibana kumda wengqolowa ukwenza imeko ye-upostrated ngexesha lenkqubo yokupholisa, ngelixa i-TI kunye ne-NB kunye ne-Tystal yamandla okukrelekrele. Xa i-weld ishushu kwakhona kuluhlu lobushushu lwemvakalelo, ikharbon ene-Superbon iya kuphangwa ngohlobo lweCR23C6 phakathi kweekristali.
a. Ukunciphisa umxholo wekhabhoni. Kwinsimbi engenasibala equkethe izinto ezizinzileyo, umxholo wekhabhoni akufuneki ungadlula kwi-0.06%.
b. Sebenzisa inkqubo ye-welding ye-welding. Khetha igalelo elincinci le-wilding lokunciphisa ixesha lokuhlala lendawo egqithileyo kwiqondo lokushisa eliphezulu, kwaye unikele ingqalelo ekuthinteleni imvakalelo ye-'im yobushushu 'ngexesha lenkqubo ye-weldia.
Xa ilokhwe enamacala amabini, i-weld inxibelelana ne-Corrosing kunye ne-Coulting Medium kufuneka ibe yeyokuthatha i-wels yokugqibela (Esi sisizathu sokuba imibhobho yangaphakathi ye-WelDeter yenziwa emva kwedls yangaphandle). Ukuba ayinakuphunyezwa, ukucaciswa kwe-welding kunye nemilo ye-weld kufuneka kulungiswe, kwaye uzame ukuphepha indawo egqithileyo ekunxibelelaneni ne-corrossive kwaye ivutha.
c. Unyango lwasemva kwe-Weld. Yenza isisombululo okanye unyango oluzinzileyo emva kwe-welding.
I-02 yoxinzelelo lokungasebenzi
La manyathelo alandelayo anokusetyenziselwa ukuthintela ukwenzeka kwe-comrosion yoxinzelelo:
a. Ngokuchanekileyo khetha kwaye ngokufanelekileyo uhlengahlengise ubume be-weld. I-chromium ephezulu ye-chromium-i-Nickel Austelitic yentsimbi, i-Silicon Chromitic Austenitic Austenitic, i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic ye-chromitic inesitayile soxinzelelo. Intsimbi yesigaba sezigaba se-sterite kunye nefrrite.
b. Susa okanye unciphise uxinzelelo lwentsalela. Ingasetyenziselwa ukuthoba impilo-yoxinzelelo yokuphelisa ubushushu obushushu, njengokunika ithuba Ukukhusela umoya kwi-on-Line-Line yokuPhakanyiswa koNyango loNyango lweZiko lokufumana umgaqo-simo. Isithando somlilo esiqaqambileyo se I-HungAo Tech (Matshini weSeko) ayifuni ukutshintsha, kuthatha kuphela imizuzwana eli-15 ukufika ngokukhawuleza iqondo lobushushu elifanelekileyo. Kwangelo xesha, inomoya obalaseleyo wokuqina, enokuthintela ngempumelelo ukubuyela umva ngomoya ngexesha lokungena. Umbhobho we-Weldied Weldid unesinyithi esifanayo kunye noxinzelelo lwe-interranir luba lincinci. Ukongeza, iindlela zoomatshini ezinjenge-Polings, ukuFumaneka kwe-Preen kunye nokuKhangela kungakunciphisa uxinzelelo olungaphezulu.
c. Uyilo lwesakhiwo esifanelekileyo. Ukuthintela uxinzelelo olukhulu.
