Zisetshenziswa kabanzi emishinini kagesi ukukhiqiza izingxenye zesekethe ezivulekile nezivaliwe. (1) Izici ze-Brazing njenge...Funda kabanzi -
Ukufakwa kwensimbi kanye ne-ceramics
1. Ukukwazi Ukubopha Kunzima ukubumba izingxenye ze-ceramic neze-ceramic, ze-ceramic nezensimbi. Iningi le-solder lakha ibhola ebusweni be-ceramic, ngokumanzisa okuncane noma okungenamanzi nhlobo. Insimbi yokugcwalisa i-brazing emanzisa i-ceramics kulula ukwenza izinhlobo ezahlukene zamakhemikhali aqhekekile (njenge-carbides, i-silicides...Funda kabanzi -
Ukushiswa kwezinsimbi ezingaphikisi
1. I-Solder Zonke izinhlobo zama-solder anezinga lokushisa elingaphansi kuka-3000 ℃ zingasetshenziswa ekushiseni kwe-W, kanti ama-solder asekelwe ethusi noma esiliva angasetshenziswa ezingxenyeni ezinezinga lokushisa elingaphansi kuka-400 ℃; Izinsimbi zokugcwalisa ezisekelwe egolideni, ezisekelwe kuma-manganese, ezisekelwe kuma-manganese, ezisekelwe kuma-palladium noma ezisekelwe ekubholeni zivame ukusetshenziswa...Funda kabanzi -
Ukubopha izinsimbi ezisebenzayo
1. Izinto zokubopha (1) I-Titanium kanye nezinsimbi zayo eziyisisekelo azivamile ukufakwa nge-solder ethambile. Izinsimbi zokugcwalisa i-brazing ezisetshenziselwa ukubopha zifaka phakathi isisekelo sesiliva, isisekelo se-aluminium, isisekelo se-titanium noma isisekelo se-titanium zirconium. I-solder esekelwe esiliva isetshenziswa kakhulu ezingxenyeni ezinokushisa okusebenzayo okungaphansi ...Funda kabanzi -
Ukubilisa ngama-alloy ethusi nethusi
1. Izinto zokubopha (1) Amandla okubopha ama-solder amaningana asetshenziswa kakhulu ekubambeni kwethusi nethusi aboniswe kuthebula 10. Amandla ethebula 10 ezihlanganisi zethusi nethusi eziboshwe ngethusi Lapho ubamba ithusi nge-tin lead solder, i-brazing flux engaboli njengesisombululo se-rosin alcohol noma i-rosin esebenzayo...Funda kabanzi -
Ukufakwa kwe-aluminium kanye ne-aluminium alloys
1. Ukukwazi Ukuqina Ukuqina kokuqina kwe-aluminium kanye ne-aluminium alloys kuphansi, ikakhulukazi ngoba ifilimu ye-oxide ebusweni kunzima ukuyisusa. I-aluminium inamandla amakhulu okusebenzisa umoya-mpilo. Kulula ukwakha ifilimu ye-oxide eqinile, eqinile futhi ephezulu yokuncibilika i-Al2O3 ebusweni. Ngesikhathi esifanayo,...Funda kabanzi -
