CuAl10Ni5Fe4 aluminium bronze inlaid graphite tooj liab tes tsho
CuAl10Ni5Fe4 txhuas bronze inlaid nrog graphite tooj liab tes tsho yog ib tug high-kev ua tau zoo tooj liab alloy matrix self-lubricating zawv zawg bearing. Nws txhim khu nws tus kheej-lubricating kev ua tau zoo los ntawm inlaying graphite nyob rau hauv lub txhuas bronze matrix. Cov khoom siv no ua ke nrog lub zog siab, zoo txhua yam khoom thiab corrosion kuj ntawm txhuas bronze nrog lub zoo lubrication ntawm graphite, ua rau nws nrov heev nyob rau hauv industrial daim ntaub ntawv. Cov hauv qab no yog qee qhov tseem ceeb thiab kev siv ntawm CuAl10Ni5Fe4 txhuas bronze inlaid graphite tooj liab tes tsho:
Cov tshuaj muaj pes tsawg leeg: Cov ntsiab lus tseem ceeb ntawm CuAl10Ni5Fe4 suav nrog txhuas (Al), npib tsib xee (Ni), hlau (Fe), thiab tooj liab (Cu) ua cov matrix. Cov ntsiab lus ntawm aluminium yog 8. , thiab cov seem yog tooj liab.
Mechanical zog: Cov hlau no muaj zog tensile siab thiab hardness. Lub zog tensile ntau dua 590 MPa, hardness yog ntau dua 150 HB, thiab lub zog tawm los thiab elongation kuj muaj kev ua tau zoo.
Lub cev muaj zog: Qhov ceev ntawm CuAl10Ni5Fe4 yog 7.8 g / cm³, linear expansion coefficient yog 1.6·10^-5/degree, thermal conductivity nyob nruab nrab ntawm 38 ~ 55 W / (m·k), thiab elastic coefficient yog 90 ~ 110 KN / mm² ntawm.
Self-lubrication: Lub inlay ntawm graphite muab cov khoom zoo rau nws tus kheej lubricating, tso cai rau lub tes tsho CuAl10Ni5Fe4 tooj liab kom muaj kev sib txhuam coefficient tsawg thiab hnav tus nqi thaum lubrication tsis txaus.
Hnav tsis kam: Vim qhov sib ntxiv ntawm graphite, hnav tsis kam ntawm lub tes tsho tooj liab nyob rau hauv cov kev sib txhuam qhuav tau zoo dua, thiab qhov siab tshaj plaws dynamic load tuaj yeem ncav cuag 70 N / mm².
Kev khiav hauj lwm kub: CuAl10Ni5Fe4 lub tes tsho tooj liab muaj qhov dav ntawm kev ua haujlwm kub, txij li -40 degree mus rau +350 degree, yoog mus rau ntau qhov chaw ua haujlwm.
Tus nqi PV: Nyob rau hauv qhov sib txawv lubrication tej yam kev mob, qhov siab tshaj plaws PV tus nqi ntawm lub tes tsho tooj liab CuAl10Ni5Fe4 kuj txawv. Nws yog 1.25 N / mm²·m / s nyob rau hauv qhuav kev sib txhuam thiab 2.45 N / mm²·m / s nyob rau hauv cov roj lubrication tej yam kev mob.
Kev sib txhuam coefficient: Kev sib txhuam coefficient yog {{0}}.12 ~ 0.16 nyob rau hauv qhuav kev sib txhuam, thiab txo mus rau 0.03 ~ 0.08 nyob rau hauv cov roj lubrication.
Daim ntawv thov teb: CuAl10Ni5Fe4 lub tes tsho tooj liab yog tsim rau cov ntawv thov uas xav tau lub zog siab, zoo lubrication muaj peev xwm thiab tsis kam rau seawater corrosion, xws li bearings, worms, thiab lwm yam hnav-resistant qhov chaw.
Specifications thiab qauv: Ntxiv nrog rau cov khoom lag luam, Jiaxing Gurun tseem tuaj yeem muab cov khoom tsis yog qauv lossis cov kev pabcuam customized raws li cov neeg siv khoom xav tau.
CuAl10Ni5Fe4 txhuas bronze inlaid graphite tooj liab lub tes tsho yog ib qho zoo tagnrho cov khoom siv xaiv hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm hnyav, vim nws cov khoom siv txhua yam thiab nws tus kheej lubricating zog.
