Iindaba

Ukuba usebenza kwi-metal casting, uyazi ukuba iziphene ezifana ne-porosity, inclusions, okanye ii-cracks zibiza kangakanani.Izihluzi zeCeramic Foam (CFF) azizo nje “izihluzo”—zisisixhobo esibalulekileyo sokucoca isinyithi esinyibilikisiweyo, ukuphucula ukuthembeka kokubumba, kunye nokunciphisa inkunkuma yemveliso. Kodwa zisetyenziselwa ntoni kanye kanye? Makhe sihlalutye usetyenziso lwazo oluphambili ngokweshishini kunye nohlobo lwesinyithi, ukuze ubone ukuba zihambelana njani nomsebenzi wakho.

1. Ukuphosa isinyithi esingenasinyithi: Yenza i-aluminium, i-copper, i-zinc Castings ingabi nasiphako

Iintsimbi ezingezizo i-ferrous (i-aluminium, i-copper, i-zinc, i-magnesium) zisetyenziswa kakhulu kwiimoto, kwii-elektroniki, nakwiimbhobho—kodwa ukunyibilika kwazo kuxhomekeke kwi-oxide inclusions kunye namaqamza egesi. IiCeramic Foam Filters zilungisa oku ngokubamba ukungcola ngaphambi kokuba zifikelele kwi-mold.

Iindlela eziphambili zokusetyenziswa apha:

Ukuphoswa kweAluminiyam (eyona meko inkulu yokusetyenziswa ngaphandle kwentsimbi):

Izihluzi zisusa ii-oxide ze-Al₂O₃ kunye nenkunkuma encinci kwi-aluminium enyibilikisiweyo, ziqinisekisa ukuba zibuthuntu kwaye ziqinile. Ifanelekile:

Izixhobo zemoto:Amavili, iibhloko zeenjini, iindawo zokuhambisa (iziphene ezimbalwa zithetha ubomi obude).

Izinto ze-Aerospace:Ii-alloy ze-aluminium ezilula zeefreyimu zeenqwelo-moya (zifuna isinyithi esicocekileyo kakhulu).

Impahla zomthengi:Izitya zokupheka ze-aluminium, iibhokisi zelaptop (akukho ziphako zomphezulu).

Ukuphoswa kweCopper kunye neBrass:

Ibamba izinto ezifakwe kwi-sulfide kunye neziqwenga ezingenakukhanyelwa, ithintela ukuvuza:

Iindawo zokufaka amanzi:Iivalvu, izixhobo, iipayipi (ezibalulekileyo ekusebenzeni okungangeni manzi).

Izixhobo zombane:Izihlanganisi zebrass, iiterminals (ubhedu olucocekileyo luqinisekisa ukuqhuba kakuhle kombane).

Ukuphoswa kweZinc kunye neMagnesium:

Izihluzi zilawula ukwakheka kwe-oxide kwi-high-pressure die casting (HPDC) ye:

Izixhobo zombane:Iikheyisi zefowuni ze-zinc alloy, iifreyimu zelaptop ze-magnesium (iindonga ezincinci azidingi ziphene).

Izixhobo:Izibambo zomnyango zeZinc, izixhobo zamandla zemagnesium (umgangatho ohambelanayo).

2. Ukuphosa iFerrous Metal: Intsimbi elungisiweyo, iiCasting zentsimbi ezisetyenziswa kakhulu

Iintsimbi ze-ferrous (intsimbi, isinyithi esityhidiweyo) zijongana noxinzelelo oluphezulu—kodwa ukunyibilika kwazo kubushushu obuphezulu (1500°C+) kufuna izihluzi eziqinileyo. Ii-Ceramic Foam Filters apha zithintela i-slag, iziqwenga ze-graphite, kunye nee-oxides ezonakalisa amandla.

Iindlela eziphambili zokusetyenziswa apha:

Ukwenziwa kweNsimbi kunye neNtsimbi engatyiwayo:

Iyamelana nokunyibilika kwentsimbi eshushu ukuze ivelise iindawo ezithembekileyo:

Oomatshini bemizi-mveliso:Iivalvu zentsimbi, imizimba yepompo, iibhokisi zegiya (akukho mifantu yangaphakathi = ixesha lokungasebenzi elincinci).

Ulwakhiwo:Izibiyeli zesakhiwo sentsimbi engenasici, izihlanganisi ze-rebar (zimelana nokugqwala).

Izixhobo zonyango:Izixhobo zotyando zentsimbi engenasici, izinki zesibhedlele (isinyithi esicocekileyo = ukusetyenziswa okukhuselekileyo).

Ukuphosa Isinyithi:

Iphucula ulwakhiwo lwe-microstructure:

Iimoto:Iidiski zebrake zentsimbi ezingwevu, ii-crankshaft zentsimbi ezithambileyo (zilawula ukungqubana kunye ne-torque).

Izixhobo ezinzima:Izixhobo zetrektara yesinyithi, imihlathi yesityumza (ifuna ukumelana nokuguguleka).

Iipayipi:Imibhobho yamanzi yentsimbi engwevu (akukho kuvuza okuvela kwizinto ezifakiweyo).

3. Ukuphosa okuKhethekileyo okunobushushu obuphezulu: I-Tackle Titanium, ii-Refractory Alloys

Kwizicelo ezigqithisileyo (i-aerospace, i-nuclear), apho iintsimbi zishushu kakhulu (1800°C+) okanye zisebenza ngokukhawuleza (titanium), izihluzo eziqhelekileyo ziyasilela. Izihluzo zeCeramic Foam (ngokukodwa ezisekelwe kwi-ZrO₂) zezona sisombululo kuphela.

Iindlela eziphambili zokusetyenziswa apha:

Ukuphoswa kweTitanium Alloy:

Ii-titanium melts zisabela kwizinto ezininzi—kodwa izihluzi ze-ZrO₂ azihlali zingasebenzi, nto leyo eyenza:

Iindawo zeenqwelo-moya:Iibhloko zeenjini zeTitanium, izixhobo zokufika zeenqwelo-moya (zifuna isinyithi esicocekileyo kakhulu ukuze ziphakame kakhulu).

Izinto ezifakelweyo kwezonyango:Ukutshintshwa kwe-titanium hip, izithintelo zamazinyo (akukho kungcoliswa = i-biocompatible).

Ukuphoswa kweAlloy eRefractory:

Izihluzi ze-superalloys ezingezizo iiferrous (ezisekelwe kwi-nickel, ezisekelwe kwi-cobalt) ze:

Ukuveliswa kombane:Iindawo ze-turbine zegesi ze-nickel-alloy (zisebenza kwi-1000°C+ exhaust).

Ishishini lenyukliya:I-Zirconium alloy fuel cladding (imelana nemisebe kunye namaqondo obushushu aphezulu).

Kutheni iiCeramic Foam Filters zibetha ezinye iindlela?

Ngokungafaniyo neengcingo zocingo okanye izihluzi zesanti, ii-CFF:

Inesakhiwo esineembobo ze-3D (ibamba ukungcola okuninzi, nokuba kuncinci).

Melana namaqondo obushushu agqithisileyo (1200–2200°C, kuxhomekeke kwizinto ezisetyenzisiweyo).

Sebenza nazo zonke izinyithi ezinkulu (i-aluminium ukuya kwi-titanium).

Nciphisa amazinga enkunkuma eseleyo ngama-30–50% (gcina ixesha kunye nemali).
