Tungsten Electrode ee alxanka TIG
Muuqaalka ballaadhan ee sayniska casriga ah iyo warshadaha, doonta tungsten waxay u soo baxdaa sidii qalab cajiib ah oo leh codsiyo kala duwan oo muhiim ah.
Doomaha Tungsten waxaa laga sameeyay tungsten, bir caan ku ah sifooyinkeeda gaarka ah. Tungsten waxay leedahay meel dhalaalaysa oo aad u saraysa, kulaylka kulaylka oo aad u wanaagsan, iyo iska caabin cajiib ah oo ku wajahan falcelinta kiimikada. Tayadani waxay ka dhigayaan walxaha ugu fiican ee abuurista maraakiibta u adkeysan kara xaaladaha daran.
Mid ka mid ah codsiyada aasaasiga ah ee doomaha tungsten waa goobta kaydinta faakuumka. Halkan, doontu waxay ku kululaatay heerkul sare oo qolka faaruqa ah dhexdiisa. Alaabta lagu rakibay doonta way uumi oo ku shubaa substrate, samaynta filimo khafiif ah oo dhumucdiisuna tahay iyo ka kooban yahay. Habkani waa lama huraan marka la samaynayo semiconductors. Tusaale ahaan, soo saarista microchips, doomaha tungsten waxay caawiyaan kaydinta lakabyada alaabta sida silikon iyo biraha, abuurista wareegyada adag ee awood u leh adduunkeena dhijitaalka ah.
Dhinaca muraayadaha indhaha, doomaha tungsten ayaa door muhiim ah ka ciyaara. Waxaa loo isticmaalaa in lagu dhejiyo dahaarka muraayadaha iyo muraayadaha, kor u qaadista milicsiga iyo gudbintooda. Tani waxay keenaysaa in la hagaajiyo waxqabadka aaladaha indhaha sida kamaradaha, telescopes, iyo nidaamyada laysarka.
Warshadaha hawada sare waxay kaloo ka faa'iidaystaan doomaha tungsten. Qaybaha soo gaadha heerkul sare iyo jawi adag inta lagu jiro safarka hawada sare ayaa la sameeyay iyadoo la isticmaalayo meel la kantaroolo oo ay fududeeyeen doomahan. Alaabta lagu kaydiyay habkan ayaa bixiya caabbinta kulaylka sare iyo adkeysiga.
Doomaha Tungsten ayaa sidoo kale lagu shaqaaleysiiyay horumarinta agabka cusub ee kaydinta tamarta iyo beddelka. Waxay gacan ka geystaan isku-dhafka iyo sifaynta alaabta baytariyada iyo unugyada shidaalka, iyaga oo kaxeynaya raadinta xalal tamar oo waxtar leh oo waara.
Cilmi baarista maadiga ah, waxay awood u yeelaan daraasadda marxaladda kala-guurka iyo sifooyinka walxaha hoos yimaada xaaladaha uumiga. Tani waxay ka caawisaa saynisyahano inay fahmaan oo ay maamulaan hab-dhaqanka agabka heerka atomiga.
Intaa waxaa dheer, soo saarista lakabyo gaar ah oo loogu talagalay codsiyada warshadaha kala duwan, doomaha tungsten waxay xaqiijiyaan labiska iyo codsiga saxda ah ee alaabta, kor u qaadida waxqabadka iyo cimri dhererka dusha sare ee daboolan.
Doonta tungsten waa qayb lagama maarmaan u ah tignoolajiyada casriga ah ee badan. Awooddeeda fududaynta kaydinta walxaha la xakameeyey iyo uumi-baxa waxay ka dhigtaa awood furaha horumarka dhinacyo badan, qaabaynta mustaqbalka sayniska iyo warshadaha.
Kala duwanaanshaha alaabtayada caadiga ah
Waxaan u soo saarnay doomo uumi ka samaysan molybdenum, tungsten, iyo tantalum codsigaaga:
Doomaha uumi-baxa ee Tungsten
Tungsten waa mid aad u adkaysa daxalka marka loo eego biro badan oo dhalaalay, oo leh meesha ugu sareysa ee dhalaalidda biraha oo dhan, aad bay ugu adkaysataa kulaylka. Waxaan ka dhignaa walxaha xitaa kuwo u adkaysta daxalka oo cabbir ahaan deggan anagoo adeegsanayna dopants gaar ah sida silicate potassium.
Doomaha uumiga molybdenum
Molybdenum waa bir gaar ah oo deggan oo sidoo kale ku habboon heerkulka sare. Lagu dahaadhay lanthanum oxide (ML), molybdenum xitaa waa u adkaysi badan tahay ductile iyo daxalka u adkaysta. Waxaan ku darnaa yttrium oxide (MY) si aan u wanaajino shaqada farsamada ee molybdenum
Doomaha uumi baxa Tantalum
Tantalum waxay leedahay cadaadis uumiga oo aad u hooseeya iyo xawaaraha uumi-baxa oo hooseeya. Waxa ugu cajaa'ibka badan maaddadan, si kastaba ha ahaatee, waa iska caabbinta daxalka sare.
Cerium-Tungsten Electrode
Electrodes-ka Cerium-Tungsten waxay leeyihiin waxqabad bilawga ah oo wanaagsan oo hoos yimaada xaaladda qulqulka hoose. Qulqulka hadda jira waa hooseeyaa, sidaas darteed electrodes-yada waxaa loo isticmaali karaa alxanka tuubooyinka, qaybo aan wasakh lahayn iyo kuwo ganaax ah. Cerium-Tungsten waa doorashada koowaad ee lagu beddelayo Thoriated Tungsten oo hoos yimaada xaaladda DC hoose.

Lanthanated Tungsten Electrode
Tungsten-ka lanthanated wuxuu noqday mid caan ka ah wareegga alxanka ee adduunka wax yar ka dib markii la sameeyay sababtoo ah waxqabadkiisa alxanka oo wanaagsan. Korantada korantada ee tungsten lanthanated ayaa aad ugu xiran tan 2% ee Tungsten ka welwelsan. Alxanleyaashu waxay si sahal ah ugu beddeli karaan tungsten Electrode ee murugsan iyagoo isticmaalaya korantada tungsten-ka ee AC ama DC mana aha inay wax isbeddel ah ku sameeyaan barnaamijka alxanka. Shucaaca ka yimaadda tungsten-ka xun ayaa sidaas laga fogaan karaa. Faa'iidada kale ee tungsten lanthanated waa in ay awoodaan in ay xamili karaan qulqulka sare iyo haysashada heerka ugu hooseeya ee khasaaraha gubashada.

| WL20 | La2O3 | 1.80 - 2.20% | <0.20% | Inta kale | 2.8 - 3.2 | buluug cir |
Electrode Tungsten Zirconiated
Tungsten Zirconiated wuxuu leeyahay waxqabadka wanaagsan ee alxanka AC, gaar ahaan marka la joogo culeyska sareeyo. Electrodes kasta oo kale marka la eego waxqabadkiisa aadka u fiican ma bedeli karo koronto-dhaliyaha tungsten Zirconiated. Electrode-ku waxa uu hayaa dhamaadka baallaha marka alxanka, taas oo keenta in daxalka tungsten yaraado iyo caabbinta daxalka wanaagsan.
Shaqaalaheenna farsamo waxa ay ku hawlanaayeen cilmi-baadhis iyo shaqo tijaabin waxaanay ku guulaysteen in ay xaliyaan isku dhacyada u dhexeeya waxa ku jira zirconium iyo guryaha farsamaynta.

Tungsten oo la burburiyay
Tungsten Thoriated waa sheyga tungstenka ah ee inta badan la isticmaalo, Thoria waa walxo shucaac ah oo hooseeya, laakiin waxay ahayd tii ugu horeysay ee muujisa horumar la taaban karo oo laga sameeyay tungsten saafi ah.
Tungsten Thoriated waa tungsten guud oo wanaagsan oo loo isticmaalo codsiyada DC, sababtoo ah waxay si fiican u shaqeysaa xitaa marka la kordhiyo amperage dheeraad ah, sidaas darteed waxay wanaajisaa waxqabadka alxanka.

Electrode Tungsten saafi ah:Ku habboon alxanka ka hooseeya hadda beddelka;
Yttrium Tungsten Electrode:Inta badan lagu dabaqay militariga iyo warshadaha duulista oo leh shucaac cidhiidhi ah, xoog cadaadis sare leh, dhexgalka alxanka ugu sarreeya ee dhexdhexaadka iyo hadda sare;
Isku-dhafka Tungsten Electrode:Waxqabadkooda aad baa loo wanaajin karaa iyadoo lagu darayo laba ama in ka badan oo ah okssaydh Earth oo naadir ah kuwaas oo is dhammaystiraya. Isku-dhafka Electrodes-ka ayaa sidaas ka noqday wax caadi ah oo ka tirsan qoyska korantada. Nooca cusub ee Composite Tungsten Electrode ee aanu samaynay waxa lagu taxay Qorshaha Horumarinta Gobolka ee alaabta cusub.
