Kurwanya ruswa na sic na Si3n4-sic muri alumini-silicon alloy gushonga

Silicon Carbide na Silicon Nitride ifite ubushyuhe buke hamwe nicyuma cyashongeshejwe. Usibye gucengerwa na Magnesium, Nickel, Chromium atloy na ibyuma bidafite ishingiro, nta bushyuhe bwo kurwanya ibisigazwa, bityo bafite ikibazo cyo kurwanya ibisigazwa kandi bikoreshwa cyane mu nganda za Aluminiyumu.

Muri iyi mpapuro, irwanya ruswa yo gusubiramo carbide ya silicon

Dukurikije amakuru yubushakashatsi bwimikino 9 yubushyuhe bwa 1080h muri 495h muri 495.

Ingero za R-sic na Sic sic ziyongereye hamwe nigihe cyo kugana hamwe nigipimo cya ruswa cyagabanutse. Igipimo cya ruswa cyahawe umubano wa Logitormic of Dettenuation. (Ishusho 1)

Nisesengura ryingufu, urugero rwa R-Sic na Sic sin4 ubwabo nta balumunum-silicon; Mu buryo bwa xrd, umubare runaka wa aluminiyumu-silicon proak nubuso-busigaye aluminiyumu-silicon alloy. (Ishusho ya 2 - Igishushanyo 5)

Binyuze mu isesengura rya Sem, kuko igihe cya ruswa kiriyongera, imiterere rusange ya R-Sic na Sic sic 4 irarekuye, ariko nta byangiritse bigaragara. (Ishusho 6 - Ishusho 7)

Ubuso bwa tension σs / l> σs / g yimikorere hagati yamazi ya aluminium hamwe na ceramic, inguni iri hagati yimikorere ni> ibikoresho bya ceramine ntabwo bitose.

Kubwibyo, ibikoresho bya R-sic na Sicn4 nibyiza cyane mu kurwanya ruswa kuri aluminiyumu silicon ishonga kandi bafite itandukaniro rito. Ariko, ikiguzi cya sicn4-sic ibikoresho bike cyane kandi byakoreshejwe neza imyaka myinshi.
