I-alloy T-800 Cobalt-based Alloy Material Properties 

Izinto eziphathekayo

I-COBALT ALLOY T-800

Ukwakhiwa kweekhemikhali

I-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: intsalela

Iimpawu zezinto eziphathekayo

Amandla okuqina σb: 1793 MPa, elastic modulus σs: 2412 MPa, ukomelela kokwaphuka: 115 MPa·m^1/2, ubulukhuni HRC: 54～62, ingxinano: ≥8.2g/cm3.

Iimpawu eziphambili

I-T800 yenye yezinto ezisetyenziswa ngokuqhelekileyo ezisekelwe kwi-cobalt. Olona phawu lwayo lune-coefficient ephantsi ye-friction, kwaye inokumelana okugqwesileyo kokunxiba, ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu.

I-T 800 ye-cobalt-based alloys yenziwe nge-hard intermetallic compound (Laves) izigaba ezihlakazwe kwi-eutectic ethambileyo okanye i-matrix yesisombululo esiqinileyo. Babonisa ukunxiba okugqwesileyo kunye nokumelana nokuxhuzula, ukuxhathisa okuphezulu kwe-corrosion kwaye bafaneleke ngakumbi kwiimeko ezinzima zokuthambisa. Ukuxhatshazwa kokugqoka kwe-Tribaloy alloys kuxhomekeke kakhulu kwipesenti yomthamo wesigaba seLaves.

I-Tribaloy T-800 yenzelwe ukuxhathisa ukunxiba kobushushu obuphezulu kunye nokuqhawuka. Ngenxa yomxholo wechromium ephezulu, ine-oxidation egqwesileyo kunye nokumelana nokubola. I-T-800 inzima kwaye inokumelana nokunxiba okungcono kune-T-400.

I-T-800 ibonisa ukuxhatshazwa kwe-corrosion egqwesileyo kwi-acetic acid (i-50% yoxinaniso, ukubilisa) kunye ne-phosphoric acid (i-85% yoxinzelelo, i-66 ° C). Ukumelana nokugqwesa okugqwesileyo kubonwa nakwi-asidi ye-sulfuric (i-5% yoxinaniso, i-66 ° C).

Usetyenziso

I-T-800 isetyenziswa kakhulu kwishishini le-aerospace ngenxa yokunxiba kwayo kobushushu obuphezulu kunye nokuxhathisa i-galling, ingakumbi kukuqina kweeblade ze-injini ye-injini yenqwelomoya. Ukongeza, ikwasetyenziselwa ukwenza okanye ukugquma iindawo ezahlukeneyo kwindawo yokunxiba kunye ne-corrosion, enje ngeebheringi, iikhamera, iiringi zokugcina, amakhonkco e-diesel piston, izitywina zoomatshini, izihlalo zokuthwala, izitrimu zevalvu kunye nezixhobo zempompo.
