Ugbu ewu ewu bụ niile ụzọ, ma ihe kasị zuru ebe nile argon ịgbado ọkụ n'ihi ọtụtụ ihe, nke anyị ga-atụle mgbe e mesịrị.

Titanium na ya alloys

Active metal-ekesa na ọdịdị zuru ezu. Ọtụtụ na-ekwu na ọ bụ ezughị, ma ọ na-achọ ka e jiri ya tụnyere. Na nke ọ bụla, ego nke titanium na jikọrọ ọnụ ukwuu karịa ọla kọpa ma ọ bụ okenye. Nke a bụ nnọọ inogide metal. Dị ọcha ụdị ọ esịmde a ike nke 337 MPa, na alloy iji nke 1 250 MPa. The agbaze n'ókè nke titanium - 1668 degrees Celsius.

Na nkịtị okpomọkụ, ọ bụ na-eguzogide ọgwụ ka corrosion na-arụ ọrụ na-enweghị omume enyi gburugburu. Otú ọ dị, mgbe okpomọkụ esịmde 400 degrees Celsius ịnya ụgbọ e ji mara na-n'ụgbọelu. Ọ mkpatụ ike na nitrogen amalite ike oxidized site oxygen na mmiri vepo, nke idiọk egbochi ya akporo. Ọ bụ ihe kwesịrị ịrịba ama na ihe e mere adịghị ewe ọkụ cracking n'oge ịgbado ọkụ, ma ọka ya na-aghọ ibu, nke gaghịzi oru e ji mara nke metal na Weld àgwà. Onwere, anyị na-aghọta a obere na bụ titanium. titanium ịgbado ọkụ - ebe a bụ ihe ọzọ bụ na-akpali. Ka anyị mara na anyị ga-ekwu okwu.
