Ngati muli muzitsulo zopangira zitsulo, mumadziwa kuti zofooka monga porosity, inclusions, kapena ming'alu zimakhala zokwera mtengo bwanji.Zosefera za Ceramic Foam (CFF) si "zosefera" chabe -ndi chida chofunikira kwambiri choyeretsera zitsulo zosungunuka, kukonza kukhulupirika, ndi kudula zinyalala zopanga. Koma kodi kwenikweni amagwiritsa ntchito chiyani? Tiyeni tidutse ntchito zawo zazikuluzikulu zamakampani ndi mtundu wazitsulo, kuti muwone momwe zimayenderana ndi kayendetsedwe kanu

1. Kuponyera Kwachitsulo Kopanda Ferrous: Pangani Aluminium, Copper, Zinc Castings Kukhala Zopanda Cholakwika

Zitsulo zopanda chitsulo (aluminium, mkuwa, zinki, magnesium) zimagwiritsidwa ntchito kwambiri mu auto, electronics, ndi plumbing-koma kusungunuka kwawo kumakonda kuphatikizika ndi oxide inclusions ndi mpweya wa mpweya. Zosefera za Ceramic Foam zimakonza izi potchera zonyansa zisanafike pa nkhungu

Kugwiritsa Ntchito Kwambiri Apa:

Aluminium Casting (chovala chachikulu kwambiri chosagwiritsa ntchito chitsulo):

Zosefera zimachotsa ma oxide a Al₂O₃ ndi zinyalala ting'onoting'ono kuchokera ku aluminiyamu yosungunuka, kuonetsetsa kuti zosalala, zolimba. Zabwino kwa:

Zigawo zamagalimoto:Mawilo, midadada ya injini, nyumba zotumizira (zowonongeka zochepa zimatanthawuza moyo wautali).

Zamlengalenga:Ma aluminiyamu opepuka a mafelemu a ndege (amafunika zitsulo zoyera kwambiri).

Katundu wa ogula:Zophika za aluminiyamu, makapu a laputopu (palibe zilema zapamtunda).

Kuponya kwa Copper & Brass:

Misampha sulfide inclusions ndi tizidutswa refractory, kupewa kutayikira mu:

Zigawo za mapaipi:Mavavu, zomangira, mapaipi (zofunika kuti madzi asagwire ntchito).

Zida zamagetsi:Zolumikizira zamkuwa, ma terminals (mkuwa woyengedwa umatsimikizira kuyendetsa bwino).

Zinc & Magnesium Casting:

Zosefera zimawongolera kuchuluka kwa oxide mu kuponyera kwamphamvu kwambiri (HPDC) kwa:

Zamagetsi:Zinc alloy foni, mafelemu a laputopu a magnesium (makoma owonda safuna chilema).

Zida:Zinc zitseko za zitseko, zida zamphamvu za magnesium (mtundu wokhazikika).

2. Ferrous Metal Casting: Konzani Zitsulo, Iron Castings Kuti Mugwiritse Ntchito Kwambiri

Zitsulo zachitsulo (zitsulo, chitsulo chonyezimira) zimalimbana ndi kupsinjika kwakukulu-koma kutentha kwake kwakukulu kumasungunuka (1500 ° C+) zimafuna zosefera zolimba. Zosefera za Ceramic Foam pano zimatchinga slag, zidutswa za graphite, ndi ma oxide omwe amawononga mphamvu.

Kugwiritsa Ntchito Kwambiri Apa:

Kuponya Kwachitsulo & Zosapanga dzimbiri:

Imapirira zitsulo zotentha zimasungunuka kuti zipange magawo odalirika:

Makina a mafakitale:Mavavu achitsulo, matupi apompo, ma gearbox (palibe ming'alu yamkati = nthawi yocheperako).

Zomangamanga:Mabulaketi achitsulo chosapanga dzimbiri, zolumikizira rebar (imakana dzimbiri).

Zida zamankhwala:Zida zopangira zitsulo zosapanga dzimbiri, zozama zakuchipatala (zitsulo zoyera = kugwiritsa ntchito bwino).

Kuponya Iron:

Kupititsa patsogolo microstructure kwa:

Zagalimoto:Ma disks a grey iron brake, ma ductile iron crankshafts (amagwirira kugunda ndi torque).

Zida zolemera:Zigawo za thirakitala yachitsulo, nsagwada zophwanyira (zimafunika kukana).

Mipope:Mapaipi amadzi achitsulo otuwa (palibe kutayikira kwa inclusions).

3. Kuponyera Kwapadera Kwakanthawi Kwambiri: Kulimbana ndi Titaniyamu, Ma Aloyi a Refractory

Pogwiritsa ntchito kwambiri (zamlengalenga, nyukiliya), pomwe zitsulo zimakhala zotentha kwambiri (1800°C+) kapena zowonjezera (titaniyamu), zosefera zokhazikika zimalephera. Zosefera za Ceramic Foam (makamaka zochokera ku ZrO₂) ndiye yankho lokhalo.

Kugwiritsa Ntchito Kwambiri Apa:

Kuponya kwa Titanium Alloy:

Titaniyamu imasungunuka ndi zida zambiri-koma zosefera za ZrO₂ zimakhala zopanda kanthu, kupanga:

Zigawo zazamlengalenga:Mitundu ya injini ya Titaniyamu, zida zoikira ndege (zimafunika chitsulo choyera kwambiri kuti chikwere).

Zoyika zachipatala:Kusintha kwa chiuno cha Titanium, kutsekeka kwa mano (palibe kuipitsidwa = biocompatible).

Refractory Alloy Casting:

Zosefera zopanda chitsulo (zotengera faifi tambala, za cobalt) za:

Kupanga mphamvu:Zigawo za turbine ya nickel-alloy (zimagwira 1000 ° C + exhaust).

Makampani a nyukiliya:Zirconium alloy mafuta cladding (imakana ma radiation ndi kutentha kwambiri).

Chifukwa Chiyani Zosefera za Ceramic Foam Zimapambana Zosankha Zina?

Mosiyana ndi ma waya kapena zosefera mchenga, CFFs:

Khalani ndi mawonekedwe a 3D porous (amatchera zonyansa zambiri, ngakhale zazing'ono).

Kupirira kutentha kwakukulu (1200-2200 ° C, kutengera zinthu).

Gwirani ntchito ndi zitsulo zonse zazikulu (aluminium mpaka titaniyamu).

Chepetsani mitengo yazachuma ndi 30-50% (sungani nthawi ndi ndalama).

Pezani CFF Yoyenera Pankhani Yanu Yogwiritsira Ntchito

Kaya mukuponya zida zamagalimoto za aluminiyamu, mavavu achitsulo chosapanga dzimbiri, kapena ma implants a titaniyamu, tili ndi Zosefera za Ceramic Foam zogwirizana ndi zosowa zanu. Zosefera zathu zimakwaniritsa miyezo ya ISO/ASTM, ndipo gulu lathu limakuthandizani kusankha zinthu zoyenera (Al₂O₃ ya aluminiyamu, SiC yachitsulo, ZrO₂ ya titaniyamu).

Lumikizanani nafe lero kuti mupeze zitsanzo zaulere komanso mawu owerengera. Lekani kulimbana ndi zolakwika zoponya - yambani kupanga zida zopanda cholakwika ndi CFF!
