Maxay tahay sababta birta leh kaarboonka ka kooban yahay ay si fudud u jebiyaan? Qaybta 1
Baararka kaarboonku ku badan yahay ayaa marar badan jabay, sida birta ka samaysan 45 # birta ah, kuwaas oo jabi doona wakhti yar ka dib. Qaadashada muunado qaybaha jaban iyo samaynta falanqaynta biraha, badanaa suurtagal maaha in la helo sababta, xitaa haddii ay aad u fog tahay in la helo sababo qaar, maaha sababta dhabta ah.
Si loo hubiyo xoog sare, kaarboon waa in sidoo kale lagu daraa birta, kaas oo ay ku soo daadan karto karbohaydraytyada birta. Marka laga eego dhinaca korantada kiimikaad ee aragtida, carbide birta waxay u shaqeysaa sidii cathode, oo dardar galinaysa falcelinta kala dirida anodic ee agagaarka substrate-ka. Kordhinta jajabka mugga carbides-ka birta ee ku dhex jira qaab-dhismeed-yar ayaa sidoo kale loo aaneynayaa sifooyinka hoos-u-dhaca hydrogen-ka ee karbide-yada.
Dusha sare ee birta waa ay fududahay in la dhaliyo oo la nuugo hydrogen. Marka atamka hydrogen-ka ay galaan birta, jajabka mugga hydrogen ayaa laga yaabaa inuu kordhiyo, ugu dambeyntii iska caabinta hydrogen ebrittlement ee walxaha si weyn ayaa loo yareeyaa.
Hoos-u-dhaca weyn ee iska caabbinta daxalka iyo iska caabbinta hydrogen ebrittlement ee birta xoogga badan ma aha oo kaliya inay waxyeello u geystaan sifooyinka birta, laakiin sidoo kale waxay si weyn u xaddidaysaa codsiga birta.
Tusaale ahaan, marka birta baabuurtu ay la kulanto bey'ado kala duwan oo daxalka leh sida koloriinta, iyadoo ay ku hoos jirto ficilka walaaca, ifafaale ee dildilaaca daxalka (SCC) ee laga yaabo inuu dhaco waxay khatar weyn ku keeni doontaa badbaadada jidhka baabuurka.
Mar kasta oo ay ka kooban tahay kaarboonku, waxa hoos u dhacaya isku xidhka faafinta haydarojiin iyo waxa sarreeya milanka hydrogen. Aqoonyahan Chan ayaa mar soo jeediyay in cilladaha kala duwan ee daahyada sida qulqulka (sida goobaha dabinka ee atamka hydrogen), awoodda, iyo daloolada ay la siman yihiin kaarboonka. Korodhka ka kooban kaarboonku waxa uu hor istaagi doonaa fidinta haydaroojin, sidaa awgeed isku xidhka faafinta hydrogen sidoo kale wuu hooseeyaa.
Maadaama maadada kaarboonku ay la mid tahay milanka hydrogen, way sii weynaataa jajabka mugga carbides sida dabinnada atomka hydrogen, yaraanta isku-dhafka hydrogen faafinta gudaha birta, way sii weyn tahay milanka hydrogen, iyo milanka hydrogen sidoo kale waxaa ku jira macluumaad ku saabsan hydrogen firdhisan. markaa u nuglaanshiyaha embrittlement Hydrogen ayaa ah kan ugu sarreeya. Kordhinta maadada kaarboonka, isku-xidhka faafinta atomyada hydrogen-ka ayaa hoos u dhacaya waxaana kor u kaca xoogga haydaroojin, taas oo ay sababtay hoos u dhaca xad-dhaafka ah ee hydrogen-ka ee dusha birta.
