Silicon Carbide na silicon nitride nwere obi ọjọọ na-enweghị ihe na-adịghị mma. E wezụga ịbụ onye a na-enye afọ ojuju site na magnesium, nickel, Chromium alloy na igwe anaghị agba nchara, n'ihi ya, ha nwere ọgba aghara na ụlọ ọrụ Aluminom.
Na mpempe akwụkwọ a, corrosion iguzogide nke recrystalized silicon carbide R-silicon nic carbide si si3n4-sị alloy na-enyocha site na ọtụtụ latitide.
Dabere na data nnwale nke oge 980h na 485h na 495 Celsius C ~ 620 ~ 620 Celsius-si silon alloy na-agbaze, a na-enweta nsonaazụ nyocha.
Oge nlele R-Sic na Si3n4-Si3n4 na-abawanye na oge corrosion na corrosion ahụ belata. Corrosion ọnụego sitere na mmekọrịta Bagetrithmic nke ịkpụzi. (Ọgụgụ 1)
Site na nyocha nke ike ọ bụla, nyocha r-s-s-sea na si3n4-smmeples sicles na-enweghị alumin-silicon; N'ime usoro XDD, ụfọdụ ego nke aluminom na-elu bụ elu aluminom-si silicon alloy. (Ọgụgụ 2 - Ọgụgụ 5)
Site na otu nyocha, dị ka oge corrosion na-abawanye, ihe owuwu nke r-Si3n4-Si3n4-Si3n4 na-atọgbọ, mana mbibi doro anya. (Ọgụgụ 6 - Ọgụgụ 7)
N'elu elu a na - emegharị σs / l> σs / g nke mmiri mmiri a alluminium na seramiiki bụ> 90 Celsius, na interface mmiri na mpempe akwụkwọ na-adịghị mmiri.
Ya mere, r-sIC na Si3n4-Si34 dị mma na nguzogide corrosion megide aluminom silicon gbazee ma nwee obere ọdịiche. Agbanyeghị, ọnụ ahịa nke ihe si3n4-sIC dị ala dị ala ma tinye ya n'ọrụ ruo ọtụtụ afọ.
