Yini ebangela ukuthi i-porosion ibe yinkinga ekusakazweni kwe-bronze?

Ama-pores ekusakazeni kwethusi (kufaka phakathi ithusi, ithusi, ithusi elinsomi, njll.) Ingabe iziphene ezijwayelekile zokuphonsa, okuvame ukubangelwa yi-Evolution ye-Gas eLeworten, ukuphathwa kabi kwesihlabathi esibunjiweyo noma isikhunta, nezinqubo ezingafanele ezincibilikisiwe, nezinye izinto. Lokhu okulandelayo yizizathu ezithile nezisombululo:

1, izinhlobo nezimpawu zezimpawu ze-stomata ezi-1 zezimpawu ze-pores: ezincane, ezihlakazekile, eziyindilinga noma ze-elliptical, zitholakala kakhulu ezingxenyeni eziwugqinsi zokugcina noma endaweni yokugcina. Isizathu: Amagesi ancibilikisiwe ngoketshezi lwethusi (njenge-H ₂ Co, i-vapor yamanzi iqonde futhi amafomu ama-bubble ngesikhathi sokuqina.  

2. Izici zama-pores asebenzayo: izindonga ezibushelelezi noma ezibushelelezi, ezivame ukuvela noma eziseduze kobuso. Isizathu: Uketshezi lweCopper uphendula ngamakhemikhali ngesihlabathi sokubumba, ukunamathela noma isilayidi ukukhiqiza amagesi (njenge-co ₂, ngakho-ke ₂).  

I-3. Izici ze-Roll in pores: ukwakheka okungajwayelekile, kuvame ukuhambisana nokufakwa kwe-slag, kusatshalaliswa eceleni kokugeleza kwensimbi. Isizathu: Ngesikhathi senqubo yokuthela, igesi idonswa kwinsimbi ebilisiwe (njengokuthululwa kwesiyaluyalu nokuphehla kabi).  

2, ukuhlaziywa kwesizathu esikhulu

1. Ukutholwa kwe-hydrogen ngesikhathi senqubo yokunqwabanisa (isici esibalulekile): I-Copper Liquid ithambekele kakhulu ekutholeni igesi ye-hydrogen emazingeni okushisa aphezulu (ikakhulukazi ithusi ne-solubility ye-hydrogen yehla kakhulu ngesikhathi sokuqina, kwakha ama-pores. Umthombo: Izimpahla zomlilo zimanzi, onamafutha, noma ziqukethe izinto eziphilayo (ezifana ne-recycled Copper equkethe uwoyela namafutha). Imvelo encibilikayo inomswakama ophezulu (njengokungakhethi ngokweqile ngesikhathi semvula). Ukuvuselelwa kwamafutha anele (isithando somlilo wegesi, isithando somlilo seCoke sikhiqiza umphunga wamanzi).  

2. I-denixidation enganele iphumela kwi-oxidation of Copper liquid ukwenza i-CU ₂ O, ephendula nge-hydrogen: Cu ₂ O ₂ ₂ → → 2cu + h ₂ O ↑ *, 2cu + Okuvame ukubonwa ku: Phosphor Bronze (edinga i-phosphorus deoxidation), ithusi (alezeli le-zinc boilishation dexidation).  

3 Izikebhe ezinganele noma iziteshi zokuphekela phansi zivimbela igesi ekuphunyukeni.  

4. Izinkinga zesihlabathi / isikhunta: Ukulwa komoya okumpofu kwesinkwa sesihlabathi (njengokuhlangana okuphezulu nokungalahla kabi kwesihlabathi se-sodium siliulium silication). Lapho i-resin isihlabathi noma isihlabathi samafutha senziwe, i-birner ikhipha inani elikhulu legesi (efana ne-H ₂ ne-CH ₄ ekhiqizwa ukuwohloka okushisa okuphezulu kwe-furan resin). Lapho usakaza isikhunta sensimbi, isikhunta asinayo ama-grooves affectris noma ukuhlanganiswa kukhulu kakhulu.  

I-5 Ayivunyelwe ngokuphelele ukuyixazulula (ithululwe ngaphandle kokukhipha uketshezi lwethusi). 3, Isixazululo

1. Ukucwengelwa kokulawula ukulawula kwe-degassing I-Brass: Sebenzisa umphumela "wokuzibandakanya" we-zinc ukususa i-hydrogen futhi ulawule izinga lokushisa elincibilikise Izinto zomiswa zokomiswa: Imfucuza yethusi idinga ukugcwala ukuze kususwe amabala e-oyela, kanye nokufakwa kwamathuluzi wesithando namathuluzi kudinga ukushiswa ngaphambi kokuncibilika. Ukuvikelwa kwesembozo: Mboza uketshezi lwethusi ngamalahle noma ingilazi slag ngesikhathi sokuncwilisa ukucwilisa ukuhlukanisa umphunga wamanzi.  

2. Ukusebenziseka kohlelo lokuthulula ukwamukela umjovo ongezansi noma othela uhlelo lokuthela ukunciphisa isiyaluyalu. Khulisa isilinganiso sendawo yesigaba sesigaba sabagijimi be-transverser nabangaphakathi (isb. 1: 2: 1.5) bese wehlisa i-flow velocity. Setha izikhwama zokuqoqa ama-slag kanye nama-riser wokukhipha amandla (ikakhulukazi ezindaweni ezibucayi nezikhulu).  

I-3. Ukuthuthuka kwesihlabathi / isikhunta I-Metal Mold Casting: Isikhunta sihlome nge-groove eqeda amandla (ukujula okungu-0.1 ~ 0.3mm) futhi sihlanganiswe nopende we-zinc onide. Isihlabathi se-Resin: Yehlisa inani le-resin elingezwe noma shintshela ku-nitrogen resin ephansi.  

4. Icubungula ukulungiswa kwepharamitha yokulungiswa okuthululelwayo: 1200 ~ 1250 ℃ nge-Copper, 980 ~ 1050 ℃ yethusi, 1100 ~ 1180 ℃ yethusi. Kancane kancane kupholile ngemuva kokuthela (njengokumboza ngesihlabathi sokufakelwa) ukwelula isikhathi sokukhishwa kwegesi.  

I-5 Ukucutshungulwa kweposi: Ukucindezela okushisayo okushisayo (i-HIP) kwenziwa ekusakazweni kokhiye ukuqeda i-zangaphakathi. I-4, icala elijwayelekile le-Brass (Cu Zn) I-porolity (i-zinc zn) iholela ku- "Zinc Boatiliving iholela ku-" Zinc Boatiling "kanye ne-Redidial hydrogen great → okuqukethwe kwe-zn okumele kulawulwa (≤ 40%), futhi kuvuselelwa ukuthi kuqiniswe ngesikhathi kuncibilikisa. I-Tin Bronze (CU-SN-P) I-porobision: i-phosphorus dooxidation noma i-sn oxidation → 0.05% ~ 0.05% phosphorus yethusi kudinga ukungezelelwa ngokuphonsa i-oxidation ngokushesha ukuze unciphise i-oxidation ngokushesha ukuze unciphise i-oxidation ngokushesha ukuze weqe i-oxidation.  

Ngokuphenya ngezinqubo ezihlelekile ngokuncibilika, ukwakheka, nokuthulula, kungenzeka ukuthi kunciphise kakhulu izinkinga ze-porosion e-Cast Copper. Uma inkinga iqhubeka, kunconywa ukuthi kuqhubeke nokuthola umthombo wegesi ngokuhlaziywa kwe-metallographic of Pore
