Kookaha Batroolka ee Graphite (GPC)

Sharaxaad Gaaban:

Kookaha batroolka ee Graphite waxaa si weyn loogu isticmaalaa sidii kor u qaadis kaarboon ah warshadaha sameynta birta iyo saxnaanta shubka, sida tarbiye warshadaha macdanta, sida wakiilka yareeya warshadaha birta iyo sida walxaha iska caabiya. Kookaha batroolka ee Graphite wuxuu kor u qaadi karaa nucleation-ka graphite ee xalka birta, wuxuu kordhin karaa xaddiga birta ductile wuxuuna hagaajin karaa habaynta iyo heerka birta la shubay ee cawlan. Iyada oo loo marayo indha-indheynta qaab-dhismeedka yar, kookaha batroolka ee graphite wuxuu leeyahay sifooyinka soo socda: Marka hore, maadada ferrite ee birta ductile si weyn ayaa loo kordhin karaa iyada oo aan la isticmaalin xasiliyeyaasha pearlite; Marka labaad, saamiga garaafka qaabaysan ee V iyo qaabka VI waa la kordhin karaa inta lagu jiro isticmaalka; Marka saddexaad, marka la barbar dhigo hagaajinta qaabka khad nodular, koror weyn oo ku yimaada qadarka khad nodular wuxuu yareyn karaa isticmaalka wakiilada nucleating-ka qaali ah ee hagaajinta dambe, taasoo keenta keydin kharash badan.
