Ike mgbaji σb: 1793 MPa, modulus σs: 2412 MPa, ike mgbaji: 115 MPa·m^ 1/2, ike HRC: 54 ~ 62, njupụta: ≥8.2g/cm3.

Isi njirimara

T800 bụ otu n'ime alloys dabere na cobalt. Akụkụ kachasị ya bụ ọnụọgụ esemokwu dị ala, yana ọ nwere nguzogide eyi nke ọma, nguzogide corrosion na oke okpomọkụ.

T 800 cobalt dabeere alloys na-emi esịnede siri ike intermetallic compound (Laves) n'ụzọ gbasasịrị na a softer eutectic ma ọ bụ siri ike ngwọta matrix. Ha na-egosipụta oke iyi na njide ọdịdọ, nguzogide corrosion dị elu ma dabara adaba maka ọnọdụ mmanye siri ike. Nguzogide iyi nke Tribaloy alloys na-adabere n'ụzọ dị ukwuu na pasent olu nke usoro Laves.

Emebere Tribaloy T-800 iji guzogide iyi akwa na abrasion dị elu. N'ihi ọdịnaya chromium dị elu, ọ nwere ezigbo oxidation na nguzogide corrosion. T-800 siri ike ma nwee nguzogide iyi ka mma karịa T-400.

T-800 na-egosiputa nguzogide corrosion dị mma na acetic acid (50% ntinye, esi) na phosphoric acid (85% ntinye, 66 Celsius C). A na-ahụkwa nguzogide corrosion dị mma na sulfuric acid (5% ntinye, 66°C).

A na-eji T-800 eme ihe n'ọtụtụ ebe na ụlọ ọrụ ikuku n'ihi oke okpomọkụ ya na nkwụsi ike ya, ọkachasị n'ịkwado eriri igwe turbine ụgbọ elu. Na mgbakwunye, a na-ejikwa ya arụpụta ma ọ bụ kpuchie akụkụ dị iche iche na akwa akwa na gburugburu corrosion, dị ka bearings, cams, mgbanaka ejigide, mgbanaka piston dizel, akara igwe, oche na-ebu, valvụ trims na akụrụngwa mgbapụta.
