GusabaIsi idasanzweMu bikoresho byateganijwe
Ibintu bidasanzwe byisi bifite imiterere yihariye ya 4f yihariye, umwanya munini wa magneti, guhuza bikomeye hamwe nibindi biranga. Iyo bigize ibigo nibindi bintu, umubare wabo wo guhuza urashobora gutandukana kuva kuri 6 kugeza 12. Ibice byisi byisi bifite imiterere itandukanye. Imitungo idasanzwe yumubiri na shimi yisi idasanzwe ituma bakoreshwa cyane mugusebanya nicyuma cyuzuye nibuka, ibikoresho bidasanzwe bya magnet, ibikoresho byo kubika hydrogen, ibikoresho byo kubika hydrogen, ibikoresho bya kirimbuzi, nibikoresho bya kirimbuzi, nibindi bikoresho. Hamwe niterambere rihoraho ryibikoresho bigizwe nibisanzwe nabyo byagutse kumurima wibikoresho bigizwe no kunoza imitungo hagati yibikoresho bitandukanye.
Uburyo nyamukuru busaba isi idasanzwe mugutegura ibikoresho bigizwe nibi: ① OngerahoNtibisanzwe Ibyuma ByisiIbikoresho bigizwe; Ongeraho muburyo bwaNtibisanzwe isi oxideku bikoresho bigizwe; Polymes yakorewe cyangwa ihujwe n'inda y'isi idasanzwe muri polymers ikoreshwa nk'ibikoresho bya matrix mu bikoresho bisanzwe. Muburyo butatu bwavuzwe haruguru bwisi bukoreshwa kwisi, impapuro ebyiri zambere ziyongereyeho ibyuma matrix, mugihe cya gatatu gikoreshwa cyane muri Matrix, hamwe na Matric yongeyeho ahanini muburyo bwa kabiri.
Isi idasanzweAhakorwa ahanini kuri metrix ya Matrix na ceramic matric muburyo bwo kwiyandikisha, abiganje, no kuzamura imikorere yabo, bikaba umusaruro, no gukora ibiciro byayo bishoboka.
Ongeraho isi idasanzwe nkuko inkingi mubikoresho bigizwe ahanini igira uruhare mugutezimbere ibikoresho byimikorere no guteza imbere ibinyampeke bya Matrix. Uburyo bwo gukora ni bukurikira.
Kunoza urubuga hagati yicyuma na plat yicyiciro cyo gushimangira. Amashanyarazi ya electronegame yibintu bidasanzwe ni hasi cyane (bito bya electronegame yibyuma, niko bakora cyane cyane ibikorwa bya electronegativis). Kurugero, LA ni 1.1, CE ni 1.12, na y ni 1.22. Amashanyarazi ya electronegame yicyuma gisanzwe ni 1.83, ni 1.91, na al ni 1.61. Therefore, rare earth elements will preferentially adsorb on the grain boundaries of the metal matrix and reinforcement phase during the smelting process, reducing their interface energy, increasing the adhesion work of the interface, reducing the wetting angle, and thereby improving the wettability between the matrix and reinforcement phase. Ubushakashatsi bwerekanye ko kongeramo ikintu cya LaUmininum kuri matrix ya aluminiyumu neza itezimbere uruzitiro rwa alo na aluminimu, kandi ruzamura ibikorwa by'ibikoresho bihimbano.
② Guteza imbere gutunganya ibinyampeke ya matrix. Kukeshagura isi idasanzwe mubyuma birimbyi ni bito, kubera ko radiyo ya atome yisi idasanzwe, kandi radiyo ya atome ya matrix ni nto. Kwinjira mubintu bidasanzwe byisi bifite radiyo nini muri matrix lattice bizatera akagoreka gusa, bizamura ingufu za sisitemu. Kugirango ukomeze imbaraga zubusa, Isi idasanzwe Indwara irashobora gutuza gusa kumyambizi zidasanzwe, zikaba zibangamira gukura kwubusa ku binyampeke. Muri icyo gihe, abacungutse ku isi nta gaciro bazemera kandi izindi eloy erecoment, kongera ibitekerezo by'ibitabo, bituma ibice by'ibintu bihurira, no kuzamura ingaruka z'ibihe by'ibyuma bya Matrix. Byongeye kandi, ibisimba biterwa no gutandukanya ibintu bitoroshye birashobora guteza imbere ishyirwaho ryimiterere itandukanye kandi ikaba ibice byiza byikirere, bityo bigateza imbere ibinyampeke bya Matrix.
③ Isura imipaka y'ibinyampeke. Kubera ubuhinzi bukomeye hagati yisi idasanzwe nibintu nkibintu nka o, s, p, sc., Etc., Etc. These compounds have a high melting point and low density, some of which can be removed by floating up from the alloy liquid, while others are evenly distributed within the grain, reducing the segregation of impurities at the grain boundary, thereby purifying the grain boundary and improving its strength.
Twabibutsa ko, kubera ibikorwa byo hejuru no guhuza ibice bike byisi, mugihe cyongewe mubyuma Matrix, guhura na ogisijeni bigomba kugenzurwa byimazeyo mugihe cyo kongeraho muburyo bwo kongereranwa muburyo bwo kongerwaho.
Imigenzo myinshi yagaragaye ko yongeraho okiside isigatiye yisi nkintagondwa, hamwe na privice ya matrix itandukanye yicyuma nubuka bwa Matric Matrix, Matric Matric yangiza cyane imbaraga nubukaze bwibikoresho, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ubushyuhe bwabo, bityo bigabanya ibiciro byumusaruro. Uburyo nyamukuru bwibikorwa byayo ni bukurikira.
① Nkumuntu wongeyeho, irashobora guteza imbere kurera no kugabanya uburozi mubikoresho bisanzwe. Ongeramo inyongeramusaruro zirote ni ugutanga icyiciro cyamazi ku bushyuhe bwo hejuru, bigabanya ubushyuhe bwimirire yibikoresho mugihe cyimikorere mugihe cyicyiciro cyamazi cyahantu. Kubera ihungabana ryinshi, intege nke-zubushyuhe bwo hejuru, kandi zishonga cyane kandi zitetse kandi zirashobora gukora ibyiciro byisi byisi, birashobora gukora ibyiciro byisi byisi hamwe nibindi bikoresho bibisi no guteza imbere umutekano, bikaba bituma bakorora neza. Muri icyo gihe, inzoka idasanzwe yisi irashobora kandi gukora igisubizo gikomeye na matrix ceramic, ishobora kubyara ubunebwe bwa Crys imbere, ikora akadomo kandi iteze imbere.
Kunoza ibikorwa bya microse no gutunganya ingano. Due to the fact that the added rare earth oxides mainly exist at the grain boundaries of the matrix, and due to their large volume, rare earth oxides have high migration resistance in the structure, and also hinder the migration of other ions, thereby reducing the migration rate of grain boundaries, inhibiting grain growth, and hindering the abnormal growth of grains during high-temperature sintering. Bashobora kubona ibinyampeke bito kandi byumyanda, bifasha gushiraho inzego zidasanzwe; Ku rundi ruhande, ukingira oxide idasanzwe y'isi, binjira mu kirahure cy'ingano, zizamura imbaraga z'ikirahure bityo ukagera ku ntego yo kuzamura imitungo y'ibikoresho.
Ibice bidasanzwe byisi mubikoko bya polymer Matrix birabagiraho ingaruka muburyo bwo kunoza imitungo matrix polymer. Intama zidasanzwe zirashobora kongera ubushyuhe bwamabuye ya polymers, mugihe udasanzwe yisi Ikarwabushobora guteza imbere ubushyuhe bwa chloride ya polyviny. UGengize Polystyrene hamwe nibice byisi bidasanzwe birashobora guteza imbere imbaraga za PUBLYSYTY no kongera imbaraga imbaraga nimbaraga zayo.
