Qalabka Daawaha ee Tungsten Copper
Sharaxaada
Tungsten Copper (CuW, WCu) ayaa loo aqoonsaday inay tahay walxo isku dhafan oo aad u firfircoon oo tirtiraya oo si weyn loogu isticmaalo korantada tungsten ee EDM mashiinnada iyo codsiyada alxanka iska caabinta, xiriirada korantada ee codsiyada tamarta sare, iyo weelasha kulaylka iyo agabyada kale ee elektiroonigga ah. codsiyada kulaylka.
Saamiyada tungsten/naxaasta ugu caansan waa WCu 70/30, WCu 75/25, iyo WCu 80/20.Halabuurka kale ee caanka ah waxaa ka mid ah tungsten/naxaas 50/50, 60/40, iyo 90/10.Kala duwanaanshaha halabuurka la heli karo waa Cu 50 wt.% ilaa Cu 90 wt.%.Kala duwanaanshaha alaabtayada naxaasta tungsten waxaa ka mid ah ul tungsten naxaas ah, bireed, xaashi, saxan, tuubo, usha naxaasta tungsten, iyo qaybo la farsameeyay.

Astaamaha
Inta lagu jiro samaynta daawaynta tungsten naxaasta, tungsten nadiif ah oo sarreeya ayaa la riixaa, la miisaamaa ka dibna la dhex geliyaa naxaasta aan ogsajiinta lahayn ka dib tallaabooyinka xoojinta.Daawaynta naxaasta tungsten ee la isku daray waxay soo bandhigaysaa qaab-dhismeed yar oo isku mid ah iyo heer hoose oo porosity ah.Isku darka korriinka naxaasta iyo cufnaanta sare ee tungsten, engegnaanta, iyo barta dhalaalka sare waxay soo saartaa isku-dhafan leh sifooyin badan oo horudhac ah oo labada walxood ah.Copper-infiltrated tungsten waxay ku faantaa sifooyin ay ka mid yihiin iska caabbinta sare ee heerkulka sare iyo arc-erosion, kulaylka iyo korantada aad u fiican iyo CTE hooseeya (isku-dhafka kulaylka).
Qalabka jirka iyo farsamada iyo barta dhalaalaysa ee tungsten naxaasta ah ayaa si togan ama liddi ku ah u saameeya kala duwanaanshiyaha qadarka tungsten naxaasta ah ee isku dhafan.Tusaale ahaan, marka maadada naxaasta ah ay si tartiib tartiib ah u korodho, korantada iyo kulaylka kulaylka iyo ballaarinta kulaylka waxay muujinayaan u janjeera inay sii xoogaystaan.Si kastaba ha ahaatee, cufnaanta, caabbinta korantada, qallafsanaanta iyo xoogga waa la wiiqi doonaa marka lagu dhex galo qadar yar oo naxaas ah.Sidaa darteed, ka kooban kiimiko ku habboon ayaa ah muhiimadda ugu weyn marka la tixgelinayo naxaasta tungsten ee baahida codsi gaar ah.

Codsiyada
Isticmaalka naxaasta Tungsten (W-Cu) ayaa si muuqata u kordhay meelo badan iyo codsiyo sababtoo ah sifooyinka farsamada iyo heerkulbeegga ee gaarka ah.Maaddooyinka naxaasta ee Tungsten waxay soo bandhigaan waxqabad heer sare ah oo ku saabsan dhinacyada adkaanta, xoogga, dhaqdhaqaaqa, heerkulka sare, iyo caabbinta nabaad-guurka.Waxaa si aad ah loogu isticmaalay soo saarista xiriiriyeyaasha korantada, kulaylka kululeeyaha iyo faafiyaasha, korantada EDM ee dhimanaysa iyo tuubooyinka lagu duro shidaalka.
