Kev paub txog kev lag luam tooj liab: tooj liab-nickel alloy ntom thiab tooj liab-nickel alloy yam ntxwv
Dab tsi yog tooj liab-nickel alloy? Dab tsi yog qhov ceev ntawm tooj liab-nickel alloy? Dab tsi yog cov yam ntxwv ntawm tooj liab-nickel alloy? Ua ntej teb cov lus nug no, cia peb txiav txim siab ua ntej. Lub ntsiab lus ntawm qhov ntom: Hauv physics, qhov sib piv ntawm qhov loj ntawm cov khoom rau lub ntim ntawm cov khoom yog hu ua qhov ntom ntawm cov khoom. Qhov ntom ntawm tooj liab-nickel alloy yog nruab nrab ntawm tooj liab thiab npib tsib xee: 8.9-8.88 (g/cm3).
Taw qhia rau tooj liab-nickel alloy: tooj liab Cu thiab npib tsib xee Ni yog silvery dawb nrog metallic luster, li no lub npe dawb tooj liab. tooj liab thiab npib tsib xee tuaj yeem yaj mus tas li hauv ib leeg los tsim cov kev daws teeb meem tas mus li, uas yog, txawm tias qhov sib piv ntawm ib leeg yog npaum li cas, nws yog ib txwm --ib theem alloy. Thaum npib tsib xee melted rau hauv liab tooj liab D200, thaum cov ntsiab lus ntau tshaj 16%, cov xim ntawm resulting alloy ua kuj dawb li nyiaj. Qhov siab dua cov ntsiab lus nickel, cov xim dawb. Txawm li cas los xij, tom qab tag nrho, thaum fused nrog tooj liab, tsuav yog cov ntsiab lus nickel tsis tshaj 70%, qhov muag liab qab yuav pom cov xim daj ntawm tooj liab. Feem ntau cov ntsiab lus nickel hauv tooj liab dawb feem ntau yog 25%.
Chav tsev ntawm tooj liab-nickel alloy ceev:
1. Gram/cm3, qhov raug nyeem yog gram ib cubic centimeter, lub cim yog g/cm3 (los yog g/mL);
2. Kilogram/decimeter3; Qhov kev nyeem ntawv raug yog kilogram ib cubic decimeter, lub cim yog kg / dm3 (los yog kg / L).
Copper-nickel alloy density formula:
Cov mis mos ceev: ρ=m/V, ρ=dm/dV (ρ sawv cev qhov ntom, m sawv cev loj, V sawv cev ntim)
Tom qab tham txog qhov ceev ntawm tooj liab-nickel alloy, cia peb saib cov yam ntxwv ntawm tooj liab-nickel alloy:
Ntshiab tooj liab ntxiv rau npib tsib xee tuaj yeem txhim kho lub zog, tiv thaiv corrosion, hardness, tsis kam thiab thermoelectricity, thiab txo qhov kub coefficient ntawm resistivity. Yog li ntawd, cov khoom siv hluav taws xob thiab lub cev ntawm cov tooj liab dawb yog qhov txawv txav zoo piv nrog rau lwm cov tooj liab alloys, nrog cov ductility zoo, siab hardness, xim zoo nkauj, corrosion kuj thiab sib sib zog nqus nqus kev ua tau zoo. Qhov tsis zoo ntawm cov tooj liab dawb yog qhov tseem ceeb ntxiv-nickel yog cov khoom siv tsis tshua muaj tswv yim thiab tseem kim heev.
Tom qab nkag siab cov yam ntxwv ntawm tooj liab-nickel alloy, cia peb kawm txog kev siv ntau ntawm tooj liab-nickel alloy:
Ntawm cov tooj liab alloys, tooj liab dawb muaj kev tiv thaiv corrosion zoo heev thiab yooj yim rau cov duab, txheej txheem thiab vuam. Nws yog dav siv los ua cov txheej txheem corrosion-resistant nyob rau hauv shipbuilding, roj av, tshuaj lom neeg kev lag luam, kev tsim kho, hluav taws xob, precision instruments, cov cuab yeej kho mob, suab paj nruas tsim thiab lwm yam departments. Qee cov tooj liab dawb kuj muaj cov khoom siv hluav taws xob tshwj xeeb thiab tuaj yeem siv los ua cov khoom siv hluav taws xob, cov khoom siv thermocouple thiab cov xaim them nyiaj. Tsis yog kev lag luam dawb tooj liab yog siv los ua cov khoom siv dai kom zoo nkauj.
