Alloy dabeere na ígwè/Nickel alloy/Nickel alloy/corrosion eguzogide superalloy superalloy efere.

Superalloys nke dabere na nickel bụ klas nke mmiri ozuzo alloys siri ike na-arụ ọrụ nke ọma na gburugburu oke okpomọkụ. Ngwongwo dị elu dị elu nke superalloys nke nickel arụpụtala mmejuputa nke klas a n'ime ọtụtụ ngwa ikuku.

Superalloy dabeere na ígwè bụ ụdị superalloy. A na-akọwa ya site n'ịgbakwunye ihe ndị ọzọ na-adabere na ígwè maka alloying. Nkwekọ na superalloys dabeere na ígwè bụ superalloys dabeere nickel na cobalt dabeere superalloys.

Superalloys dabeere na Cobalt bụ ihe eji eme ihe na oke okpomọkụ yana oke gburugburu nwere oke okpomọkụ dị elu, nguzogide corrosion na iyi mgbochi. Superalloys dabere na cobalt bụ ihe mejupụtara nke ọma dịka cobalt, chromium, tungsten, nickel na aluminom.

Alloys ndị na-eguzogide corrosion na-enye mmụba nke ike igwe, iguzogide nrụrụ ọkụ, yana iguzogide corrosion ma e jiri ya tụnyere alloys ọdịnala, na-achọ obere mmezi yana iguzogide gburugburu ebe siri ike. A na-eme mbọ iji mepụta nnukwu alloys na-eguzogide corrosion ọhụrụ dị ka aluminom dabeere na super alloys, yana imepụta ụzọ ọhụrụ nke nrụpụta dị ka radiolysis nke na-eji nano-particle synthesis maka imepụta polycrystalline.

Igwe ọkụ dị elu na nguzogide corrosion nke superalloy na-adabere na nhazi na nhazi ya. Inweta Inconel718 nickel dabeere deformed superalloy dị ka ihe atụ, alloy mejupụtara a γ matrix na-adọ, a δ frasi, a carbide, na a ike γ na γ "phase.
