I-Tungsten Copper Alloy Rods
Inkcazo
I-Copper tungsten (i-CuW, i-WCu) iye yaqatshelwa njengeyona nto iqhutywe kakhulu kunye ne-erasion resistant composite material esetyenziswa ngokubanzi njenge-electrode ye-tungsten yobhedu kwi-EDM ye-machining kunye ne-resistance welding applications, uqhagamshelwano lombane kwizicelo zombane ophezulu, kunye nokutshisa ukushisa kunye nezinye izinto zokupakisha ze-elektroniki. kwizicelo ze-thermal.
Umlinganiselo oqhelekileyo we-tungsten / ubhedu yi-WCu 70/30, i-WCu 75/25, kunye ne-WCu 80/20.Ezinye iingoma eziqhelekileyo ziquka i-tungsten / ubhedu 50/50, 60/40, kunye ne-90/10.Uluhlu lweengoma ezikhoyo lusuka kwi-Cu 50 wt.% ukuya kwi-Cu 90 wt.%.Uluhlu lwethu lwemveliso yobhedu lwe-tungsten lubandakanya intonga ye-tungsten yobhedu, i-foil, i-sheet, ipleyiti, ityhubhu, intonga yobhedu ye-tungsten, kunye neengxenye zomatshini.

Iimbonakalo
Ngexesha lokwenziwa kwe-alloy ye-tungsten yobhedu, i-tungsten yococeko oluphezulu iyacinezelwa, ifakwe i-sintered kwaye ifakwe nge-oxygen-free copper emva kwamanyathelo okudibanisa.I-alloy yobhedu ye-tungsten edibeneyo ibonisa i-microstructure ene-homogeneous kunye nenqanaba eliphantsi le-porosity.Ukudityaniswa kokuqhuba kobhedu kunye noxinaniso oluphezulu lwetungsten, ubulukhuni, kunye neqondo eliphezulu lokunyibilika kuvelisa umdibaniso oneempawu ezininzi ezibalaseleyo zazo zombini iziqalelo.I-tungsten ye-Copper-infiltrated iqhayisa iimpawu ezifana nokuchasana nokushisa okuphezulu kunye ne-arc-rosion, i-thermal egqwesileyo kunye ne-electrical conductivity kunye ne-CTE ephantsi (i-coefficient of thermal).
Iimpawu ezibonakalayo kunye nemishini kunye neqondo lokunyibilika kwezinto zethusi ze-tungsten ziya kuchaphazeleka ngokufanelekileyo okanye ngokuchaseneyo ngokuhluka kobuninzi be-tungsten yobhedu kwi-composite.Ngokomzekelo, njengoko umxholo wobhedu ukhula ngokuthe ngcembe, i-conductivity yombane kunye ne-thermal kunye nokwandiswa kwe-thermal kubonisa ukuthambekela kokuba namandla.Nangona kunjalo, ukuxinana, ukuxhathisa kombane, ubunzima kunye namandla kuya kuba buthathaka xa kungeniswa ngobhedu oluncinci.Ngoko ke, ukubunjwa kweekhemikhali ezifanelekileyo kubaluleke kakhulu xa kuqwalaselwa ubhedu lwe-tungsten kwimfuno ethile yesicelo.
Ukwandiswa kwe-thermal ephantsi
I-thermal ephezulu kunye ne-conductivity yombane
Ukumelana ne-arc ephezulu
Ukusetyenziswa okuphantsi
Usetyenziso
Ukusetyenziswa kobhedu lweTungsten (W-Cu) kuye kwanda ngokuphawulekayo kwiindawo ezininzi kunye nezicelo ngenxa yeempawu zayo ezihlukeneyo zomatshini kunye ne-thermophysical.Izixhobo zobhedu zeTungsten zibonisa ukusebenza okuphezulu okugqwesileyo kwimiba yokuqina, amandla, ukuqhuba, ubushushu obuphezulu, kunye nokumelana nokukhukuliseka kwe-arc.Isetyenziswe kakhulu kwimveliso yoqhagamshelwano lombane, izitshizi zokufudumala kunye ne-spreaders, i-electrode ye-EDM yokufa kunye nemibhobho ye-fuel injection.
