Okubalulekile
I-COBALT ALLOY T-800
Ukwakheka kwamakhemikhali
I-Cr: 16.5-18.5%; I-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: okusele
Izinto ezibonakalayo
Amandla aqinile σb: 1793 MPa, elastic modulus σs: 2412 MPa, ukuqina kokuphuka: 115 MPa·m^1/2, ubulukhuni HRC: 54～62, ukuminyana: ≥8.2g/cm3.
Izici eziyinhloko
I-T800 ingenye yama-alloys asekelwe ku-cobalt asetshenziswa kakhulu. Isici sayo esikhulu kunazo zonke i-coefficient ephansi ye-friction, futhi inokumelana okuhle kakhulu nokugqokwa, ukumelana nokugqwala kanye nokumelana nokushisa okuphezulu.
Ama-alloys e-T 800 asekelwe ku-cobalt akhiwe ngezigaba eziqinile ze-intermetallic compound (Laves) ezihlakazwe ku-eutectic ethambile noma isixazululo esiqinile se-matrix. Zibonisa ukumelana okuhle kakhulu kokuguga nokubamba, ukumelana nokugqwala okuphezulu futhi zifaneleka kakhulu izimo ezinzima zokugcoba. Ukumelana nokugqoka kwama-alloys e-Tribaloy kuncike kakhulu kumaphesenti wevolumu yesigaba seLaves.
I-Tribaloy T-800 yakhelwe ukumelana nezinga lokushisa eliphezulu ukuguga nokuhuzuka. Ngenxa yokuqukethwe kwayo okuphezulu kwe-chromium, ine-oxidation enhle kakhulu nokumelana nokugqwala. I-T-800 iqinile futhi inokumelana nokugqokwa okungcono kune-T-400.
I-T-800 ikhombisa ukumelana nokugqwala okuhle kakhulu ku-acetic acid (ukugxilisa okungu-50%, ukubilisa) kanye ne-phosphoric acid (i-85% yokuhlushwa, 66°C). Ukumelana nokugqwala okuhle kakhulu kubonakala ku-sulfuric acid (i-concentration engu-5%, i-66°C).
Izinhlelo zokusebenza
I-T-800 isetshenziswa kakhulu embonini ye-aerospace ngenxa yokuguga kwayo okuphezulu kwezinga lokushisa kanye nokumelana ne-galling, ikakhulukazi ku-hardfacing yama-blade enjini yendiza. Ngaphezu kwalokho, iphinde isetshenziselwe ukukhiqiza noma ukugqokisa izingxenye ezahlukahlukene ezindaweni ezigugile kakhulu kanye nokugqwala, njengama-bearings, amakhamera, izindandatho zokugcina, izindandatho ze-diesel piston, izigxivizo zemishini, izihlalo ezithwalayo, ama-valve trim kanye nezingxenye zephampu.
