Izinduku ze-Tungsten Copper Alloy
Incazelo
I-Copper tungsten (i-CuW, i-WCu) iye yaqashelwa njengento eyinhlanganisela ekwazi ukumelana nokucisha nokucisha esetshenziswa kabanzi njengama-electrode e-tungsten yethusi kuma-EDM machining kanye ne-resistance welding applications, othintana nabo kagesi ekusetshenzisweni kwamandla kagesi aphezulu, osinki bokushisa nezinye izinto zokupakisha ze-elekthronikhi. ezinhlelweni ezishisayo.
Izilinganiso ezivame kakhulu ze-tungsten/zethusi yi-WCu 70/30, i-WCu 75/25, ne-WCu 80/20.Ezinye izingoma ezivamile zihlanganisa i-tungsten/copper 50/50, 60/40, kanye no-90/10.Ububanzi bezingoma ezitholakalayo busuka ku-Cu 50 wt.% ukuya ku-Cu 90 wt.%.Uhlu lwethu lomkhiqizo wethusi we-tungsten luhlanganisa induku ye-tungsten yethusi, ucwecwe, ishidi, ipuleti, ishubhu, induku yethusi ye-tungsten, kanye nezingxenye ezenziwe ngomshini.

Izici
Ngesikhathi sokwenziwa kwe-copper tungsten alloy, i-tungsten ehlanzekile kakhulu iyacindezelwa, ifakwe i-sintered bese ingena ngethusi elingenayo umoya-mpilo ngemva kwezinyathelo zokuhlanganisa.Ingxubevange ye-tungsten yethusi ehlanganisiwe iveza i-microstructure ene-homogeneous kanye nezinga eliphansi le-porosity.Inhlanganisela ye-coppers conductivity kanye nokuminyana okuphezulu kwe-tungsten, ukuqina, nendawo encibilikayo ephezulu kukhiqiza inhlanganisela enezici eziningi ezivelele zazo zombili izakhi.I-tungsten efakwe ngethusi iqhosha ngezinto ezifana nokumelana okuphezulu nezinga lokushisa eliphezulu kanye nokuguguleka kwe-arc, ukuguquguquka okuhle kakhulu kwe-thermal kanye nogesi kanye ne-CTE ephansi (i-coefficient of thermal).
Izakhiwo zomzimba nezomshini kanye nephoyinti lokuncibilika lezinto zethusi ze-tungsten zizothinteka kahle noma ngokuphambene ngokushintsha inani le-tungsten yethusi kunhlanganisela.Isibonelo, njengoba okuqukethwe kwethusi kukhula kancane kancane, ukuqhutshwa kukagesi nokushisa kanye nokwanda kwe-thermal kubonisa ukuthambekela kokuba namandla.Kodwa-ke, ukuminyana, ukumelana nogesi, ubulukhuni namandla kuzoba buthaka uma kungenwa ngenani elincane lethusi.Ngakho-ke, ukwakheka kwamakhemikhali okufanelekile kubaluleke kakhulu uma kucatshangelwa ithusi le-tungsten ngesidingo esithile sohlelo lokusebenza.
Ukwandiswa kwe-thermal ephansi
High conductivity ezishisayo kanye kagesi
Ukumelana ne-arc ephezulu
Ukusetshenziswa okuphansi
Izinhlelo zokusebenza
Ukusetshenziswa kwe-Tungsten copper (W-Cu) kuye kwanda ngokuphawulekayo emikhakheni eminingi nasekusetshenzisweni ngenxa yezakhiwo zayo ezihlukile zemishini kanye ne-thermophysical.Izinto zethusi ze-Tungsten zibonisa ukusebenza okuphezulu okuvelele ezicini zokuqina, amandla, ukuhanjiswa, izinga lokushisa eliphezulu, nokumelana nokuguguleka kwe-arc.Isetshenziswe kakhulu ekukhiqizeni othintana nabo kagesi, amasinki okushisa nama-spreader, ama-electrode e-EDM acwilayo kanye nama-nozzles afakwe uphethiloli.
