Nickel Alloy Investment Castings

Ngati chitsulo chopangira chitsulo chiponya faifi tambala pogwiritsa ntchito njira yotayika ya phula (mtundu wa kuponyedwa mwatsatanetsatane), ndiye kuti ndalama zopangira nickel alloy zidzapezedwa. Nickel-based alloy ndi mtundu wa aloyi wapamwamba wokhala ndi faifi tambala monga matrix (zambiri kuposa 50%) ndi mkuwa, molybdenum, chromium ndi zinthu zina monga ma aloyi. Zinthu zazikulu zopangira ma aloyi a faifi tambala ndi chromium, tungsten, molybdenum, cobalt, aluminium, titaniyamu, boron, zirconium ndi zina zotero. Pakati pawo, Cr, Al, ndi zina zotero makamaka zimagwiritsa ntchito anti-oxidation effect, ndi zinthu zina zimakhala ndi njira zolimba zolimbitsa, kulimbitsa mpweya komanso kulimbitsa malire a tirigu. Ma alloys opangidwa ndi nickel nthawi zambiri amakhala ndi mawonekedwe austenitic. Mu chikhalidwe cha olimba njira ndi ukalamba mankhwala, palinso intermetallic magawo ndi zitsulo carbonitrides pa austenite masanjidwewo ndi malire a mbewu aloyi. Ma aloyi opangidwa ndi nickel ali ndi mphamvu zambiri komanso kukana kwa okosijeni kwabwino, kukana kwa dzimbiri komanso kukana kutentha kwapakati pa 650 mpaka 1000 ° C. Nickel-based alloy ndi aloyi wamba wotsutsa kutentha kwambiri. Ma aloyi opangidwa ndi nickel amagawidwa m'ma aloyi osamva kutentha kwa nickel, ma alloys osagwirizana ndi nickel, ma alloys osamva kuvala opangidwa ndi faifi, ma aloyi opangidwa ndi faifi wolondola komanso ma aloyi a kukumbukira mawonekedwe a faifi molingana ndi katundu wawo wamkulu. Ma superalloys opangidwa ndi nickel, ma superalloys opangidwa ndi chitsulo ndi ma nickel-based superalloys onse amatchulidwa kuti aloyi otentha kwambiri. Chifukwa chake, ma superalloys opangidwa ndi nickel amatchedwa ma alloys opangidwa ndi nickel. Nickel-based superalloy mndandanda wazinthu zimagwiritsidwa ntchito kwambiri muzamlengalenga, zakuthambo, mafuta, mankhwala, mphamvu zanyukiliya, zitsulo, zam'madzi, zoteteza chilengedwe, makina, zamagetsi ndi zina. Magiredi ndi njira zochizira kutentha zomwe zimasankhidwa pazigawo zosiyanasiyana zamakina zidzakhala zosiyana.
