Cov txhuas bronze tuaj yeem hloov tau los ntawm tin bronze phaj

Ua tautxhuas bronzeyuav hloov los ntawm tin bronze phaj?
Raws li ib qho elastic alloy, tin bronze phaj hais txog tooj liab-tin alloy uas muaj Sn≤6.5%, feem ntau tseem muaj P, Zn thiab lwm yam hlau alloy.Yog hais tias nws tseem muaj P, nws yog hu ua phosphor-tin bronze, uas muaj siab elastic txwv, elastic modulus, zoo kuj hnav thiab corrosion kuj, haum rau tsim ntawm ntau yam elastic Cheebtsam.Cov ntsiab lus txhuas ntawm txhuas bronze feem ntau tsis tshaj 11.5%, thiab qee zaum muaj qhov tsim nyog ntawm cov hlau, npib tsib xee, manganese thiab lwm yam khoom ntxiv los txhim kho kev ua tau zoo.Aluminium bronze tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nws lub zog yog siab dua li ntawm tin bronze phaj, thiab nws tsis kam mus rau kub oxidation kuj zoo dua.Nws yog siv rau high-strength screws, ceev, lub tes tsho tooj liab, sealing rings, thiab lwm yam., thiab hnav-resistant qhov chaw.Qhov tseem ceeb tshaj plaws feature yog nws zoo hnav tsis kam.Rau txhuas bronze muaj hlau thiab manganese cov ntsiab lus, nws muaj zog thiab hnav tsis kam.Tom qab quenching thiab tempering, lub hardness yuav nce, thiab nws muaj zoo kub corrosion kuj thiab oxidation kuj.Corrosion kuj nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv zoo heev, lub machinability tau txais, nws yuav welded thiab tsis yooj yim brazed, thiab lub siab ua hauj lwm zoo nyob rau hauv lub kub lub xeev.Ob lub tin bronze phaj thiab txhuas bronze yog cov ntaub ntawv hnav-resistant.
Txij li thaum cov hlau indenter yog deformed thaum ntsuas, cov xuab zeb hom hlau hom.Qhov loj thiab thauj khoom ntawm lub indenter tseem tsis hloov pauv, HBS, tshwj xeeb tshaj yog thaum cov khoom ntsuas yog qhov nyuaj, thiab kev sib raug zoo ntawm HBW: HB yog Brinell hardness tus nqi: ZCuSn5Pb5Zn5;Brinell hardness tus nqi nyob rau hauv tus qauv tshiab qhia meej meej qhia lub indenter thaum ntsuas: Tensile zog σb (MPa): HBW hais txog ib tug cemented carbide indenter: 590HB.Vim yog qhov deformation ntawm cov hlau indenter thaum ntsuas, tus qauv tshiab txo cov qhov khoob hauv qhov no: ≥90;elongation δ5 (%): ≥13.Nco tseg: HWS yog hais txog cov hlau indenter, yog li ntawm no yog thawj qhov sib txawv, tshwj xeeb tshaj yog thaum ntsuas cov ntaub ntawv nyuaj, tus qauv tshiab yuav txo qis qhov khoob hauv qhov no.
