Cov khoom ntawm bronze hmoov

Bronze hmoov yog cov hmoov hlau uas muaj tooj liab thiab tin, feem ntau hu ua "bronze".Ntawm cov khoom siv hmoov hlau, tooj liab yog cov khoom siv ua haujlwm zoo nrog cov khoom siv zoo heev, hluav taws xob conductivity thiab corrosion kuj.Cov tsos ntawm bronze hmoov yog cov hmoov grey, nws qhov loj me yog feem ntau ntawm 10 thiab 50μm, thiab qhov ceev yog li 7.8g / cm³.

Lub cev muaj zog

Bronze hmoov muaj lub cev ruaj khov, zoo heev hluav taws xob conductivity thiab hloov tshav kub.Nws melting point yog tsawg, 800 ~ 900 ℃, nrog zoo casting kev ua tau zoo thiab kev ua tau zoo.Tsis tas li ntawd, bronze hmoov muaj siab hardness, zoo hnav tsis kam thiab tsis yooj yim rau hnav.

Cov khoom siv tshuaj

Bronze hmoov muaj cov tshuaj ruaj khov thiab muaj zog corrosion kuj.Nws muaj kev ruaj ntseg zoo rau dej thiab cua hauv chav tsev kub thiab tsis yooj yim rau oxidized.Thaum kub kub, nws cov oxidation tsis kam thiab corrosion kuj tseem zoo dua.

Mechanical zog

Bronze hmoov muaj cov khoom siv zoo, thiab nws lub zog tensile, yield zog thiab hardness siab.Nws hnav tsis kam thiab qaug zog kuj yog qhov zoo, haum rau kev tsim khoom ntawm ntau yam khoom siv.

Thermal khoom

Lub thermal zog ntawm bronze hmoov yog zoo, nws melting point yog tsawg, thiab cov coefficient ntawm thermal expansion yog me me.Thaum kub kub, nws thermal conductivity thiab thermal stability yog zoo.

Kev siv bronze hmoov

Casting khoom

Bronze hmoov, raws li cov khoom siv zoo tshaj plaws, yog siv dav hauv kev tsim khoom ntawm ntau yam castings.Vim nws qhov qis melting point thiab fluidity zoo, nws tuaj yeem yooj yim nchuav rau hauv ntau yam duab.Bronze castings muaj qhov hnav tsis kam, tiv thaiv corrosion thiab ua haujlwm, thiab tuaj yeem siv los tsim cov khoom siv rau cov tshuab, tsheb thiab lwm yam haujlwm.

Manufacturing hav txwv yeem

Bronze hmoov tuaj yeem siv los tsim cov kabmob bushing, uas muaj kev hnav tsis kam thiab qaug zog zoo, thiab tuaj yeem tiv taus siab thiab ceev.Nyob rau hauv kev lag luam bearing, bronze bearing bushing yog dav siv nyob rau hauv ntau yam khoom siv kho tshuab, uas plays lub luag hauj lwm los tiv thaiv cov kabmob nto thiab txuas lub neej kev pab cuam ntawm cov cuab yeej siv tshuab.

Cov khoom siv hluav taws xob

Bronze hmoov muaj hluav taws xob zoo conductivity thiab corrosion kuj thiab tuaj yeem siv los ua ntau yam khoom siv hluav taws xob.Piv txwv li, nws tuaj yeem siv los ua cov khoom siv hluav taws xob, hluav taws xob rwb thaiv tsev thiab cov khoom siv hluav taws xob.Tsis tas li ntawd, bronze hmoov kuj tseem siv tau los ua cov khoom siv electroplating thiab cov ntaub ntawv ua haujlwm.

Hnav-resistant txheej

Bronze hmoov tuaj yeem siv los ua cov khoom siv hnav-tiv taus rau txheej txheej ntawm ntau yam khoom siv kho tshuab.Los ntawm kev siv cov bronze txheej, hnav tsis kam, corrosion kuj thiab kev pabcuam lub neej ntawm cov khoom tuaj yeem txhim kho.Nyob rau hauv aerospace, tub rog thiab lwm yam kev lag luam, bronze txheej yog dav siv nyob rau hauv ntau yam high-ceev, high-load qhov chaw.
