Alloy T-800 Cobalt-ishingiye kuri Alloy Material Properties 

Ibikoresho

COBALT ALLOY T-800

Ibigize imiti

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: ibisigaye

Ibikoresho

Imbaraga zingana σb: 1793 MPa, modulus ya elastike σs: 2412 MPa, gukomera kuvunika: 115 MPa · m ^ 1/2, gukomera HRC: 54 ～ 62, ubucucike: ≥8.2g / cm3.

Ibintu nyamukuru biranga

T800 nimwe mubisanzwe bikoreshwa muri cobalt. Ikintu kinini kiranga ni coefficient de fraisse nkeya, kandi ifite imbaraga zo kurwanya kwambara, kurwanya ruswa no kurwanya ubushyuhe bwinshi.

T 800 ya cobalt ishingiye ku mavuta igizwe nibice bigoye byuzuzanya (Laves) bikwirakwizwa muri matrike yoroshye ya eutectic cyangwa ikomeye. Yerekana kwambara neza no gufatwa, kurwanya ruswa cyane kandi birakwiriye cyane cyane mugihe cyo gusiga amavuta. Kurwanya kwambara kwa Tribaloy alloys biterwa ahanini nijanisha ryijwi ryicyiciro cya Laves.

Tribaloy T-800 yagenewe kurwanya ubushyuhe bwo hejuru no kwangirika. Bitewe na chromium nyinshi, ifite okiside nziza kandi irwanya ruswa. T-800 irakomeye kandi ifite kwihanganira kwambara kuruta T-400.

T-800 yerekana imbaraga zo kurwanya ruswa muri acide ya acetike (50% yibanze, guteka) na aside fosifori (85%, 66 ° C). Kurwanya ruswa nziza cyane bigaragara no muri acide sulfurike (5% yibanze, 66 ° C).

Porogaramu

T-800 ikoreshwa cyane mu nganda zo mu kirere bitewe n'ubushyuhe bwayo bukabije hamwe no guhangana na galling, cyane cyane mugukomera kwa moteri yindege ya turbine. Byongeye kandi, ikoreshwa kandi mu gukora cyangwa gutwika ibice bitandukanye ahantu hambaraye cyane no kwangirika, nko kwifata, cams, kugumana impeta, impeta ya piston ya mazutu, kashe ya mashini, intebe zifite intebe, ibyuma bya valve nibikoresho bya pompe.
