Carbura de siliciu legat\u0103 cu nitrur\u0103 este un material refractar avansat \u0219i un material structural cu numeroase caracteristici benefice, inclusiv rezisten\u021b\u0103 ridicat\u0103 la temperaturi ridicate, rezisten\u021b\u0103 excep\u021bional\u0103 la eroziune, rezisten\u021b\u0103 la \u0219ocuri termice, rezisten\u021b\u0103 la oxidare \u0219i u\u0219urin\u021ba proceselor de sinterizare, care permite formarea cu u\u0219urin\u021b\u0103 a unor forme complicate \u00een proiecte complexe.<\/p>\n
Acest material ofer\u0103 o capacitate portant\u0103 ridicat\u0103 \u0219i o rezisten\u021b\u0103 excep\u021bional\u0103 la coroziune \u00eempotriva acizilor, s\u0103rurilor topite \u0219i halogenilor. \u00cen plus, rezisten\u021ba sa la fisurarea fragil\u0103 \u00eel face o op\u021biune bun\u0103.<\/p>\n
Materialul compozit din aluminiu (ACM) ofer\u0103 o bun\u0103 rezisten\u021b\u0103 la abraziune \u00een condi\u021bii de sol liber, dar nu poate fi comparat \u00een mod favorabil cu o\u021belul \u0219i sudura de c\u0103ptu\u0219eal\u0103 \u00eempotriva uzurii prin impact. Rezisten\u021ba la abraziune cre\u0219te \u00een func\u021bie de m\u0103rimea granulelor \u0219i de tipul de acoperire. ACM poate fi g\u0103sit utilizat pentru aplica\u021bii de mobilier de cuptor \u00een procese metalurgice la temperaturi ridicate, \u00een timp ce rezisten\u021ba sa excelent\u0103 la oxidare face din acesta un material nepre\u021buit \u00een situa\u021bii de temperatur\u0103 ridicat\u0103.<\/p>\n
Carbura de siliciu legat\u0103 cu nitrur\u0103 are o rezisten\u021b\u0103 extrem de ridicat\u0103, ceea ce o face o alegere excelent\u0103 pentru ceramica tehnic\u0103 de precizie. \u00cen plus, acest material prezint\u0103 rate sc\u0103zute de dilatare termic\u0103, ceea ce \u00eel face potrivit pentru oglinzile telescoapelor astronomice.<\/p>\n
Rezisten\u021ba ceramicii la fisurarea fragil\u0103 este legat\u0103 de distribu\u021bia granulometric\u0103 a acesteia, iar ceramica a prezentat o uzur\u0103 mai pu\u021bin intens\u0103 dec\u00e2t o\u021belul \u00een toate condi\u021biile studiate, solul greu prezent\u00e2nd o uzur\u0103 de 9 ori mai pu\u021bin intens\u0103 comparativ cu 3 ori \u00een condi\u021bii de sol mediu.<\/p>\n
Materialele refractare din carbur\u0103 de siliciu legat\u0103 cu azot (NBC) sunt materiale refractare turnate, utilizate de obicei pentru a forma forme complexe folosind diverse tehnici, inclusiv presarea uniaxial\u0103 \u0219i turnarea prin alunecare. Ambele tehnici au propriul set de avantaje: presarea uniaxial\u0103 permite o eficien\u021b\u0103 ridicat\u0103 a produc\u021biei, dar este limitat\u0103 la forme cu geometrie simpl\u0103; turnarea prin alunecare permite ob\u021binerea de forme verzi, dar necesit\u0103 timp pentru uscare \u00eenainte de a se produce demodelarea.<\/p>\n
Carbura de siliciu legat\u0103 cu nitrur\u0103 (NBSiC) este un material refractar compozit excep\u021bional, oferind propriet\u0103\u021bi excep\u021bionale de \u0219oc termic, rezisten\u021b\u0103 la oxidare \u0219i rezisten\u021b\u0103 ridicat\u0103. \u00cen plus, NBSiC rezist\u0103 la umezirea de c\u0103tre metalele neferoase topite \u00een el \u00een timpul proceselor de topire; spre deosebire de moissanitul natural, care apare doar rareori \u00een meteori\u021bi, depozite de corindon sau kimberlite; majoritatea NBSiC v\u00e2ndut \u00een prezent la nivel mondial este fabricat sintetic.<\/p>\n
NB SiC poate fi produs prin nitrurare, \u00een care un amestec de carbur\u0103 de siliciu \u0219i compu\u0219i care con\u021bin azot sunt \u00eenc\u0103lzi\u021bi la temperaturi ridicate pentru a forma materiale dense \u0219i consolidate. Procesul poate fi realizat folosind dou\u0103 metode de formare distincte: presarea uniaxial\u0103 \u0219i turnarea prin alunecare. Presarea uniaxial\u0103 produce compacte geometrice simple, \u00een timp ce turnarea prin alunecare produce piese ceramice verzi de form\u0103 complex\u0103, cu structuri unice; densitatea acestora depinde de \u00eenc\u0103rc\u0103tura de solide \u0219i de con\u021binutul de liant din suspensiile respective.<\/p>","protected":false},"excerpt":{"rendered":"
