Nickel 718 Kev Sau Ntawv Thiab Lwm Cov Alloys Tseem Ceeb

Lub tshuab aerospace thiab tub rog tiv thaiv kev lag luam siv ntau yam khoom siv zoo ntawm cov hlau tsis zoo thiab cov khoom lag luam tau zoo heev thaum lawv tau ua cov khoom los ua cov ntawv cog lus tiv thaiv lawv. Qee cov qauv ntawm alloys lawv siv suav nrog cov pa roj carbon, hlau, tooj, thiab npib tsib xee. Lawv kuj siv ntau cov xaim nickel alloys, suav nrog ua cim ntawm nickel 718.

Ntawm no yog saib ntawm kev siv ntau yam ntawm alloys thiab dab tsi ua rau lawv thiaj li ua tau zoo. Plaub Zoo Hlau Txhuas Hlau Siv Los ntawm Cov Huab Cua thiab Cov Tub Rog Ua Haujlwm Siv Cov pa roj carbon monoxide: Thaum ua kom sov, cov pa roj carbon ntau ntxiv muaj zog. Nyob rau tib lub sijhawm, nws tseem nyob qis qis heev hauv kev coj ua. Yog li ntawd, cov pa roj carbon monoxide yog cov khoom siv zoo tshaj plaws los siv rau bayonets thiab lwm yam riam phom hlau, xws li riam.

Hlau: Hlau yog ib qho uas tsis tshua muaj hlau, thiab stainless hlau yog pab tau zoo li. Stainless hlau, tshwj xeeb, tsis tshua muaj siab tiv thaiv cov av noo. Vim tias huab cua tiv taus huab cua, nws yog qhov zoo tshaj plaws rau kev siv hauv cov khoom siv hluav taws xob thiab phom rab phom. Muaj qhov nce ntxiv ntawm kwv yees li 6% toj ib xyoo rau kev siv cov xeb hlau uas muaj npib tsib xee.

Tooj liab: Siv los tsim tubing, xov hlau, thiab coj tawm hle, tooj liab tau raug siab heev yog ib qho khoom siv zoo tshaj plaws los ua cov khoom no. Qhov no vim tias tooj liab tau zoo heev rau kev siv hluav taws xob. Ob lwm cov alloys ua nrog tooj liab, tooj dag thiab tooj dag, kuj tau siv rau hauv qee qhov kev siv. Bronze yog tawv heev thiab muaj zog. Qhov tseeb, nws yog kev sib xyaw ntawm tin thiab tooj liab. Thiab tooj dag, kev sib xyaw ua ke ntawm tooj liab thiab zinc, zoo rau kev siv uas tsis tshua muaj kev sib txhuam.

Nickel: Nickel yog qhov pab tau zoo vim tias nws muaj qhov ua kom tsis tshua muaj cua sov nthuav dav thiab zoo hluav taws xob tsis kam. Hauv kev qhia tshwj xeeb, nickel 718 muaj pes tsawg leeg yog cov xaim nickel uas yooj yim heev rau kev siv weld. Nws tseem muaj tshuaj tiv thaiv corrosion. Cov ob yam no ua rau cov xaim npib tsib xee 718 alloy alloy zoo siv rau hauv dej. Cov khoom muaj cov khoom siv nickel thiab nickel muaj nyob rau hauv cov khoom uas siv txhua hnub. Kev loj hlob ntawm cov khoom siv nickel yog kwv yees li 4% ib xyoo.

Thaum nriav cov hlau thiab ntau hom alloys, nws yog qhov tseem ceeb yuav tau saib cov ntaub ntawv zoo tshaj plaws muaj. Thiab tsuas yog ib qho tseem ceeb kom nco ntsoov yog tias hlau yuav tsum tau yuav los ntawm cov kws tshaj lij uas tsim tshwj xeeb kom tau txais cov khoom lag luam zoo tshaj plaws. Pib ua haujlwm nrog cov khoom siv zoo yog txoj kev zoo tshaj plaws los xyuas kom muaj txiaj ntsig zoo thiab muaj kev nyab xeeb thiab muaj txiaj ntsig zoo rau txhua tus neeg koom nrog.
