Alloy T-800 Cobalt-based Alloy Material Properties 

Material

COBALT Alloy T-800

Kemikari yakagadzirwa

Cr: 16.5～18.5%; Ni+Fe: ≤3.0%; Mo: 27.5～31.5%; C: ≤0.5%; N: ≤0.07%; Si: ≤3.5%; P: ≤0.03%; S: ≤0.03%; Co: zvakasara

Material properties

Kusimba kwesimba σb: 1793 MPa, elastic modulus σs: 2412 MPa, kuomarara kwekutsemuka: 115 MPa · m^1/2, kuoma HRC: 54～62, density: ≥8.2g/cm3.

Hunhu hunokosha

T800 ndeimwe yeanowanzo shandiswa cobalt-based alloys. Chinhu chayo chikuru ndeye yakaderera friction coefficient, uye ine yakanakisa kupfeka kuramba, corrosion resistance uye yakakwirira tembiricha kuramba.

T 800 cobalt-based alloys inoumbwa neyakaoma intermetallic compound (Laves) zvikamu zvakaparadzirwa mune yakapfava eutectic kana yakasimba mhinduro matrix. Ivo vanoratidza yakanakisa kupfeka uye kubata kubata, yakakwira corrosion kuramba uye inonyanya kukodzera kune yakaoma lubrication mamiriro. Kupfeka kuramba kweTribaloy alloys kunoenderana zvakanyanya nehuwandu hwehuwandu hwechikamu cheLaves.

Tribaloy T-800 yakagadzirirwa kurwisa kupisa kwakanyanya kupfeka uye abrasion. Nekuda kweiyo yakakwira chromium yemukati, ine yakanakisa oxidation uye corrosion kuramba. T-800 yakaoma uye ine nani kupfeka kuramba kupfuura T-400.

T-800 inoratidzira yakanakisa corrosion resistance muacetic acid (50% concentration, boiling) uye phosphoric acid (85% concentration, 66°C). Yakanakisa corrosion resistance inowanikwawo mu sulfuric acid (5% concentration, 66°C).

Applications

T-800 inoshandiswa zvakanyanya muindasitiri yezvemuchadenga nekuda kwekupfeka kwayo kwekushisa kwakanyanya uye kushomeka kwekusagadzikana, kunyanya mukuomarara kweinjini yeinjini blades. Pamusoro pezvo, inoshandiswawo kugadzira kana kupfekedza zvikamu zvakasiyana-siyana munzvimbo dzakapfeka zvakanyanya uye dzakaora, senge mabhengi, makamera, mhete dzekuchengetedza, dizeli piston mhete, zvisimbiso zvemakanika, zvigaro zvinotakura, mavharuvhu emagetsi uye zvikamu zvepombi.
