Yuav ua li cas txheeb xyuas hom tooj liab alloy

Yuav ua li cas txheeb xyuas homtooj liab alloy?
Dawb tooj liab, tooj dag, liab tooj liab (tseem hu ua "liab tooj liab"), thiab tooj liab (xiav-grey lossis grey-daj) yog qhov txawv ntawm cov xim.Ntawm lawv, tooj liab dawb thiab tooj dag yog qhov yooj yim heev kom paub qhov txawv;liab tooj liab yog tooj liab ntshiab ( impurities <1%) thiab bronze (lwm yam alloys yog hais txog 5%), uas yog me ntsis nyuaj rau qhov txawv.Thaum tsis muaj oxidized, cov xim ntawm liab tooj liab yog ci dua li ntawm bronze, thiab bronze yog me ntsis cyan los yog yellowish tsaus;Tom qab oxidation, liab tooj liab yuav dub, thiab bronze yog turquoise (muaj teeb meem oxidation ntawm dej) los yog chocolate.
Kev faib tawm thiab vuam yam ntxwv ntawm tooj liab thiab tooj liab alloys:
(1) Ntshiab tooj liab: ntshiab tooj liab feem ntau hu ua liab tooj liab.Nws muaj zoo hluav taws xob conductivity, thermal conductivity thiab corrosion kuj.Cov tooj liab ntshiab yog sawv cev los ntawm tsab ntawv +T}} (tooj liab), xws li Tl, T2, T3, thiab lwm yam. Cov ntsiab lus ntawm cov pa oxygen tsis tshua muaj qis, thiab cov tooj liab ntshiab uas tsis muaj ntau tshaj 0.01% yog hu ua oxygen-dawb tooj liab, uas yog sawv cev los ntawm TU (tooj liab dawb), xws li TU1, TU2, thiab lwm yam.
(2) Brass: Cov tooj liab alloy nrog zinc ua lub ntsiab alloying yog hu ua tooj dag.Brass siv + H;(daj) txhais tau tias H80, H70, H68, thiab lwm yam.
(3) Bronze: Yav tas los, alloy ntawm tooj liab thiab tin tau hu ua tooj liab, tab sis tam sim no tooj liab alloys uas tsis yog tooj dag hu ua tooj liab.Feem ntau siv yog tin bronze, aluminium bronze thiab min bronze.Bronze yog sawv cev los ntawm "Q" (cyan).
Lub vuam yam ntxwv ntawm tooj liab thiab tooj liab alloys yog: ① nyuaj rau fuse thiab yooj yim rau deform;② yooj yim los tsim cov kub tawg;③ yooj yim tsim pores
Copper thiab tooj liab alloy vuam tsuas yog siv cov roj vuam, cov roj inert shielded vuam, submerged arc vuam, brazing thiab lwm txoj kev.
Copper thiab tooj liab alloys muaj cov thermal conductivity zoo, yog li lawv feem ntau yuav tsum tau preheated ua ntej vuam, thiab cov kab loj loj yuav tsum tau siv rau vuam.Lub hydrogen tungsten arc vuam siv DC zoo txuas.Hauv cov roj vuam, cov nplaim nruab nrab lossis cov nplaim hluav taws tsis muaj zog carbonization yog siv rau tooj liab, thiab cov nplaim hluav taws tsis muaj zog oxidizing yog siv rau tooj dag los tiv thaiv cov evaporation ntawm zinc.
