Kukonzekera kwa scandium alloy pogwiritsa ntchito njira yotsutsa doping

Njira ya doping ndi njira yachikhalidwe yosungunulirama aloyi apakati a scandium. Zimaphatikizapo kukulunga gawo lina la chiyero chapamwambazitsulo scandiummu aluminiyamu, ndikusakaniza ndi aluminiyamu yosungunuka pansi pa chitetezo cha argon, kuigwira kwa nthawi yokwanira, kuigwedeza bwino, ndikuyiponyera muchitsulo kapena nkhungu zamkuwa zozizira kuti mupeze.ma aloyi apakati a scandium. Kusungunula kumatha kupangidwa pogwiritsa ntchito ma graphite apamwamba kwambiri kapena ma alumina crucibles, ndipo njira zotenthetsera zitha kuchitika pogwiritsa ntchito ng'anjo zotsutsana kapena ng'anjo zapakatikati. Njirayi imatha kusungunula ma aloyi apakatikati okhala ndi 2% mpaka 4%scandium.

Mfundo ya doping njira ndi yosavuta, koma kusungunuka mfundoscandiumndi aluminium amasiyana kwambiri (Sc ndi 1541 ℃, A1 ndi 660 ℃). Kusungunuka kwa aluminiyamu kumafunika kutenthedwa mpaka kutentha kwambiri, zomwe zimapangitsa kuti zikhale zovuta kukonzekera mankhwala a alloy apakatikati okhala ndi mawonekedwe okhazikika komanso kugawa yunifolomu, komanso zimakhala zovuta kupewa kuwotcha kwa scandium. Kuti akwaniritse izi, njira yowongoka ndikusakaniza ndi kukanikiza chitsulo chosungunuka kwambiri ndi dispersant, aluminiyamu ufa, flux, etc. pasadakhale panthawi yokonzekera, ndikuwonjezeranso muzitsulo zosungunuka. The dispersant amawola pa kutentha kwambiri, basi kuphwanya agglomerates, amene akhoza kupanga aloyi yunifolomu ndi kuchepetsa moto imfa ya mkulu kusungunuka zitsulo. Koma zonse, mtengo wokonzekerama aloyi apakati a scandiumkugwiritsa ntchito chiyero chapamwambascandium zitsulomonga zopangira ndizokwera kwambiri, zomwe zimakhala zovuta kuti ogwiritsa ntchito mafakitale azivomereza.
