Nts'etsopele le tlhahiso ea lisebelisoa tsa alloy tse thata tsa nonmagnetic ke lipontšo tse kholo tsa lisebelisoa tse ncha tse thata tsa alloy. Alloy e thata e entsoe ka ho tšela li-carbide tsa tšepe tse refractory tsa lihlopha tsa IV A, VA, le VI A tafoleng ea nakoana ea likarolo (tse kang tungsten carbide WC), le tšepe ea phetoho ea sehlopha sa tšepe (cobalt Co, nickel Ni, iron Fe) e le mohato oa ho kopanya ka indasteri ea phofo ea metallurgy. Tungsten carbide e ka holimo ha e na makenete, ha Fe, Co, le Ni kaofela e le makenete. Ho sebelisa Ni joalo ka setlamo ke boemo bo hlokahalang bakeng sa ho hlahisa li-nonmagnetic alloys.
Ho na le mekhoa e latelang ea ho fumana WC Ni series nonmagnetic hard alloys:1. Laola khabone ka thata
Joalo ka WC Co alloy, litaba tsa khabone ke eona ntho e ka sehloohong e amang tharollo e tiileng ea W mokhahlelong oa bonding oa WC Ni alloy. Ke hore, ho fokotseha ha carbon content ea carbon compound phase alloy, ho ba le matla a maholo a tharollo ea W karolong ea Ni bonding, ka mefuta e fapaneng ea hoo e ka bang 10-31%. Ha tharollo e tiileng ea W karolong ea Ni bonded e feta 17%, motsoako o fetoha demagnetized. Moko oa mokhoa ona ke ho fumana li-alloys tse thata tsa nonmagnetic ka ho fokotsa likahare tsa khabone le ho eketsa tharollo e tiileng ea W molemong oa ho kopanya. Ha e le hantle, phofo ea WC e nang le carbon content e tlaase ho feta ea carbon content e atisa ho sebelisoa, kapa phofo ea W e kenngoa motsoako ho finyella sepheo sa ho hlahisa li-alloys tse tlaase tsa carbon. Leha ho le joalo, ho thata haholo ho hlahisa li-alloys tse se nang makenete ka ho laola litaba tsa khabone feela.
2. Eketsa chromium Cr, molybdenum Mo, tantalum Ta
Khabone e phahameng WC-10% Ni (wt% ka boima ba 'mele) motsoako o bonts'a ferromagnetism mocheso oa kamore. Haeba ho feta 0.5% Cr, Mo, le 1% Ta li eketsoa ka sebopeho sa tšepe, alloy e phahameng ea carbon e ka fetoha ho tloha ferromagnetism ho ea ho non-magnetism. Ka ho eketsa Cr, matla a khoheli a alloy a ikemetse ka carbon content, 'me Cr ke phello ea tharollo e ngata e tiileng karolong ea ho kopanya ea alloy, joaloka W. The alloy e nang le Mo le Ta e ka fetoha feela ho ba motsoako motsoako o se nang makenete sebakeng se itseng sa khabone. Ka lebaka la tharollo e tlase e tiileng ea Mo le Ta mokhahlelong oa tlamahano, boholo ba bona ba nka feela khabone ka WC ho etsa litharollo tse tiileng tsa carbide kapa carbide. Ka lebaka leo, motsoako oa motsoako o fetoha o lebile lehlakoreng la carbon e tlaase, e leng se hlahisang keketseho ea tharollo e tiileng ea W karolong ea ho kopanya. Mokhoa oa ho eketsa Mo le Ta ke ho fumana motsoako o seng oa makenete ka ho fokotsa khabone. Leha ho se bonolo ho laola joalo ka ho eketsa Cr, ho batla ho le bonolo ho laola litaba tsa khabone ho feta WC-10% Ni alloy e hloekileng. Mefuta e mengata ea khabone e ekelitsoe ho tloha ho 5.8-5.95% ho ea ho 5.8-6.05%.
