Okuhlobisa zethusi: Ukusakaza ifomu

Ukuze wenze wezangaphakathi ukuzihlanganisa isitayela ahlukile we medieval izingcweti umhlobiso isetshenzisiwe eside ethusi, avame - zethusi. Ekubunjweni yalezi Alloys futhi manje ikuvumela ukudala yobuciko omkhulukazi ezingaba ukuhlobisa ikhaya.

Bronze: izakhiwo

Esikhathini art Ukusakaza Alloys kakhulu evame ukusetshenziswa ngaphandle metal okumsulwa. Ithusi ethandwa kakhulu - zethusi-tin ingxubevange (okufakiwe kanye element alloying) ngezabelo ahlukahlukene. Uma esikhundleni zinc tin sengezwe, umphumela uba zethusi, uma nickel - esiliva ne-nickel. Ithusi kuhlangene aluminium, beryllium noma Silicon zethusi Uphinde abhekwe. I element alloying sivezwa isiqu:

• BrO5 lapho ithini 5%;
• BrOS5-25: ehlanganisa 5% ithini 25% phambili.

Yini izakhiwo zobuchwepheshe has nethusi, na? Ukulingisa Ukuze kuveze amandla impahla. Amazinga lapho ithusi encibilikisiwe kuyinto 1083 ° C. Uma add kuwo ithini embundwini lehliselwa ku-800 ° C, okuyinto kakhulu kusiza inqubo Ukushisa okuluhlaza impahla. Ngemva solidification umkhiqizo has a ukuncipha 1%. Kuye izingxenye zethusi ware kuzohluka e ubulukhuni. Lapho inani eliphansi tin kokuzihlanganisa at lokuhlushwa 20% kanye ubulukhuni ephakeme bona aphinde abe buthakathaka. Plasticity unezela ukwethulwa phambili. Ukwengeza i-zinc kwenza izinto livikela kakhulu ukugqwala.

Bronze-Cast

metal encibilika landulelwa umsebenzi eside wokulungiselela. Omunye ingxenye yayo okungukuthi walandisa yokukhiqiza imodeli. Kulesi sigaba, lo umqophi sculpts isampuli esikalini elinama plastic. Khona-ke ilihumusha ibe usayizi ogcwele efakwe ukhonkolo noma ubumba. Nge kwalolu shintsho, imodeli isuswe isikhunta reverse. Ukuma eziyinkimbinkimbi enezinto eziningi izingxenye nezingxenye kwenzekani. Ligcwele wax eshubile. Evala ukuma, sifinyelele nokusakazwa kwayo iyunifomu phezu bonke ubuso. Ngemva lwaluyophola kwakhiwa isakhiwo esizayo ebaziwe kwakheka wax. Umbhali uphothula imininingwane, ilungisa zamehlo.

Yobuciko yabalingisi zethusi nethusi lilidlula kwenziwe okunjalo amafomu wax ( "i-stencil"). Ukuqopha etholwe eziyize enodonga ukushuba 2 - 5 mm. Uma kungenjalo, uma isizinda igcwalisa lonke ifomu, ekubunjweni okuqinile esinda kakhulu, futhi le ndaba adinga kakhulu. Futhi akusiyo kuphela izindleko zalo okusezingeni eliphezulu. Uma ugcwalisa kuzofuneka ukuthi ngokushesha ancibilike phansi yonke lemali, futhi lokhu kwandisa ngokuzenzakalelayo usayizi le somlilo inkimbinkimbi inqubo yokusebenzisa ingxubevange ukwakha. Ngaphezu kwalokho, i-ukuncipha leyo nto ngeke deformations akunakugwenywa, eliphumela amajamo esontekile izingxenye ngazinye kwengoma.

inqubo Izici

Ngemva kokudala wax yakha esigabeni esilandelayo iqala. Imbangela esithathwayo caster. Lwenza ifomu ethela metal esibunjiweyo. Stencil wanamathela ekhethekile ukushisa ukumelana Ukwakheka e ezelekene. Okokuqala, uketshezi is batheleka Ceramic isikhunta wax. Lesi sinyathelo kudala nengaphakathi - ". Isilima" Ngemva yayo ukuqina okufanayo Ukwakheka imodeli okungukuthi ngokuphelele ezimboziwe ngaphandle ngu kulungiselelwa edingekayo isibalo "unyaka", ayothunyelelwa ku ngethusi.

Udini sezivuma ngemva sintering (calcination) uyaca ezingeni lokushisa eliphezulu. Kule nqubo, bakha igobolondo Ceramic is okuqinile. Wax ayahwamuka ngokusebenzisa unyaka futhi esidayisa emoyeni. Imiphumela iba yinhlanganisela yokukhandleka ukuma eziyize. Ngemva bathele metal siphukile. Isendlalelo engaphakathi Ceramic kungabuye agcinwayo noma zisuswe ngenqubo wokuvula.

Ukulingisa zethusi ekhaya

Ukuze uthole umkhiqizo ingxubevange kungaba ngesimo emhlabeni. Ekhaya, ebukhoneni iphethini ngale ndlela, ungenza yabalingisi ngethusi. Kodwa thina kufanele lilungiselwe yokuthi ikhophi esiqondile imininingwane encane ngeke bakwazi ukufeza futhi ukuba ngcono. ifomu alahlwayo etholwe, kodwa kungenzeka ukusebenzisa umhlaba ngokwawo (ingxube yobumba nesihlabathi) ngokuphindaphindiwe. Ngokuvamile ukwenza isikhunta yokuhlukanisa ehlanganisa izingxenye ezimbili. Kodwa ungenza yonke futhi, uma usebenzisa imodeli wax. Ngemva sintering ifomu Ubumba zifakwe emanzini, wax ngokusebenzisa Letnik zintanta kwamanzi.

Ukulingisa izinga ingatholakala uma ifomu kuyoba zangaphambi sekuqala ukufudumala. Nethini kushiswa a steel Ukuphekwa Ngobhojwana NgamaFascist. Sebenzisa amalahle eziko noma muffle esithandweni. Ngemva ephelele ukuncibilika metal inakekelwa at okusezingeni eliphezulu lokushisa imizuzu embalwa futhi uthele Letnik mncane okuqhubekayo ekusakazeni. Umkhiqizo eminye kusetshenzwe emva lwaluyophola. Okokuqala sinqunyiwe kwensimbi eqina e unyaka. Izindawo zihlubule. izingxenye Izacile akhiwa inqubo minting. Umkhiqizo okungukuthi phansi, emihle, uma kufaneleka camera nge patina.
