Uhlalutyo lweeNdlela zokuSebenza kwi-Hard Alloy Strip

Sonke siyazi ukuba inxalenye ephambili ye-alloys enzima yi-micro sized carbide powders yobunzima obuphezulu kunye neentsimbi eziphikisayo. Ngoko ke, yomelele kakhulu, kwaye abantu abaninzi bayabuza ukuba i-alloy eqinile esetyenziselwa amazinyo ebhola eqinile yintsimbi? Yenzeka njani ingxubevange eqinileyo? Apha ngezantsi, umenzi we-alloy strip eqinileyo uya kukucacisela indlela yokwenziwa kwe-hard alloy ibhola izinyo elomeleleyo.

1. Indlela yokuvelisa i-long strip hard alloy yile ilandelayo: okokuqala, i-alloy bonding yenziwe ngokusila ibhola eliphezulu; Emva koko, ngokomlinganiselo omiselweyo wobunzima bezinto ezilukhuni ze-alloy, umxube wongezwa kwaye uxhomekeke ekuqiniseni ukugaya ibhola. Umxube we-alloy oqinileyo oveliswa yibhola yokusila emva koko i-vacuum sintered ukumila.

2. Ii-alloys eziqinileyo ezisetyenziselwa amazinyo omde we-hard alloy ball ikakhulukazi ziquka i-tungsten carbide (WC) kunye ne-titanium carbide (TC). Ingxubevange enzima ibandakanya ikakhulu i-tungsten cobalt esekwe (WC+Co) i-hard alloys (YG), i-tungsten titanium cobalt esekwe (WC+TiC+Co) i-hard alloys (YT), i-tungsten tantalum cobalt esekelwe (WC+TaC+Co) i-hard alloys (YA), i-tungsten titanium tantalum cobalt esekelwe (WC+Cobalt) eqinile (WC+CoYC) alloys (WC+Cobalt)

3. Uhlobo lwe-ultra-fine hard alloy ibhola izinyo eliqinileyo ialloy kunye nendlela yokuvelisa. I-alloy yialloyi ehlanganisiweyo eyenziwe ngamacandelo amathathu aphambili: isigaba se-WC esinzima, i-Co Al njengesigaba sentsimbi edibeneyo, kunye nesigaba sezinto ezinqabileyo zomhlaba; Ukubunjwa kunye nomxholo wobunzima be-alloy ngolu hlobo lulandelayo: Isigaba se-Co Al bonding metal: Al13-20%, Co80-87%; I-alloy ehlanganisiweyo: Co-AL 10-15%, Re1 ~ 3%, WC82 ~ 89%. Indlela yokuvelisa ngolu hlobo lulandelayo: okokuqala, i-alloy yokudibanisa i-Co Al iphantsi ukusuka kwiibhola eziphezulu zamandla; Emva koko, ngokomlinganiselo omiselweyo wobunzima bezinto ezilukhuni ze-alloy, umxube uxutywe kwaye uxhomekeke kwi-milling yebhola eqinisiweyo. Umxube we-alloy oqinileyo oveliswa yibhola yokusila emva koko i-vacuum sintered kwiqondo lokushisa le-sintering ye-1360 ℃ kunye nexesha lokubamba imizuzu engama-20. I-alloy eqinileyo ecolekileyo kakhulu iyaveliswa.
