1.Ni uruhe ruhare rwa buri kintu muri diyama yabonye blade matrix binder?
Uruhare rw'umuringa: Umuringa n'umuringa ushingiye ku byuma ni ibyuma bikoreshwa cyane mu bikoresho bya diyama ya binder, hamwe n'ifu ya electrolytike y'umuringa ikoreshwa cyane.Umuringa n'umuringa ushingiye ku muringa bikoreshwa cyane kubera ko umuringa ushingiye ku muringa ufite ibintu byuzuye bishimishije: ubushyuhe bwo hasi bwo gucumura, guhinduka neza no guhindagurika, no kutumvikana hamwe nibindi bintu.Nubwo umuringa utose cyane diyama, ibintu bimwe na bimwe bivangwa numuringa birashobora kuzamura cyane ubushuhe bwabyo kuri diyama.Kimwe mu bintu nka Cr, Ti, W, V, Fe bigize umuringa na karbide birashobora gukoreshwa mu gukora umuringa w’umuringa, ushobora kugabanya cyane inguni y’amazi y’umuringa kuri diyama.Ubushobozi bwumuringa mubyuma ntabwo buri hejuru.Niba hari umuringa ukabije mubyuma, bigabanya cyane ubushyuhe bwumuriro kandi bigatera kumeneka.Umuringa urashobora gukora ibisubizo bitandukanye bikomeye hamwe na nikel, cobalt, manganese, amabati, na zinc, bigashimangira ibyuma bya matrix.
Imikorere y'amabati: Amabati nikintu kigabanya ubukana bwubuso bwamazi yimyunyu ngugu kandi bigira ingaruka zo kugabanya inguni yimyunyu ngugu ya diyama.Nibintu bitezimbere guhanagura ibyuma bifatanye kuri diyama, bigabanya gushonga kwa alloys, kandi bikanoza uburyo bwo gukanda.Sn rero ikoreshwa cyane mubifata, ariko imikoreshereze yayo ni mike kubera coefficient nini yo kwaguka.
Uruhare rwa zinc: Mubikoresho bya diyama, Zn na Sn bifite byinshi bisa, nko gushonga hasi no guhinduka neza, mugihe Zn itari nziza muguhindura ubushuhe bwa diyama nka Sn.Umuvuduko wumuyaga wicyuma Zn ni mwinshi cyane kandi biroroshye guhumeka, kubwibyo rero ni ngombwa kwitondera ingano ya Zn ikoreshwa mubikoresho bya diyama.
Uruhare rwa aluminium: Ibyuma bya aluminiyumu nicyuma cyiza cyoroshye na deoxidizer nziza.Kuri 800 ℃, inguni ya Al kuri diyama ni 75 °, naho 1000 ℃, inguni ni 10 °.Ongeramo ifu ya aluminiyumu muguhuza ibikoresho bya diyama irashobora gukora karbide icyiciro Ti Å AlC hamwe na intermetallic compound TiAl muri matrix alloy.
Uruhare rw'icyuma: Icyuma gifite uruhare runini muguhuza, kimwe ni ugukora karbide karbide hamwe na diyama, ikindi ni uguhuza nibindi bintu kugirango ushimangire matrix.Ubushuhe bwa fer na diyama biruta ubw'umuringa na aluminiyumu, kandi umurimo wo gufatira hagati y'icyuma na diyama uruta uw'uwitwa cobalt.Iyo ingano ikwiye ya karubone yashongeshejwe muri Fe ishingiye ku mavuta, bizagira akamaro mu guhuza diyama.Gucisha make diyama na Fe ishingiye ku mavuta irashobora kongera imbaraga zo guhuza isano na diyama.Ubuso bwavunitse ntabwo bworoshye kandi bwambaye ubusa, ariko butwikiriwe nigice cya aliyumu, nikimenyetso cyimbaraga zo guhuza imbaraga.
Uruhare rwa cobalt: Co na Fe ni mubice byinzibacyuho, kandi ibintu byinshi birasa.Co irashobora gukora karbide Co ₂ C hamwe na diyama mubihe byihariye, mugihe ikwirakwiza firime ya cobalt yoroheje cyane hejuru ya diyama.Muri ubu buryo, Co irashobora kugabanya impagarara zimbere hagati ya Co na diyama, kandi ifite akazi gakomeye ko gufatira diyama mugice cyamazi, bigatuma iba ibikoresho byiza cyane.
Uruhare rwa nikel: Muguhuza ibikoresho bya diyama, Ni nikintu cyingirakamaro.Muri Cu ishingiye ku mavuta, kongeramo Ni birashobora gushonga bitagira akagero hamwe na Cu, bigashimangira matrix ivanze, bigabanya igihombo gike cyo gutakaza ibyuma, kandi bikongera ubukana no kwambara birwanya.Ongeramo Ni na Cu kuri Fe alloys birashobora kugabanya ubushyuhe bwo kugabanuka no kugabanya kwangirika kwubushyuhe bwumuriro wibyuma kuri diyama.Guhitamo guhuza Fe na Ni birashobora kunoza cyane imbaraga zo gufata za Fe zishingiye kuri diyama.
Uruhare rwa manganese: Mububiko bwibyuma, manganese igira ingaruka nkicyuma, ariko ifite ubushobozi bwo kwinjirira hamwe nubushobozi bwa deoxygene, kandi ikunda okiside.Umubare wiyongereye wa Mn mubusanzwe ntabwo ari mwinshi, kandi icyingenzi ni ugukoresha Mn mugukoresha deoxidisation mugihe cyo gucumura.Mn isigaye irashobora kwitabira kuvanga no gushimangira matrix.
Uruhare rwa chromium: Chromium Metal nikintu gikomeye gikora karbide kandi nikintu gikoreshwa cyane.Muri diamant groove yabonye matrix ya blade, hari chromium ihagije kugirango igire ingaruka nziza, ifitanye isano nimbaraga zo gukora Cr.Ongeramo agace gato ka Cr kuri matrike ya Cu irashobora kugabanya impande zose zogosha zumuringa ushingiye kuri diyama kandi bikongerera imbaraga imbaraga zumuringa ushingiye kumuringa.
Uruhare rwa titanium: Titanium nikintu gikomeye cya karbide ikora ibintu byoroshye okiside kandi bigoye kugabanya.Imbere ya ogisijeni, Ti nibyiza kubyara TiO2 aho kuba TiC.Icyuma cya Titanium ni ibikoresho byiza byubatswe bifite imbaraga zikomeye, kugabanya imbaraga nke mubushyuhe bwinshi, kurwanya ubushyuhe, kurwanya ruswa, hamwe no gushonga cyane.Ubushakashatsi bwerekanye ko kongeramo titanium ikwiye kuri diyama ya materi materix ifite akamaro mu kuzamura ubuzima bwa serivisi yicyuma.
2.Ni ukubera iki umubiri wicyuma ugomba guhuza ibuye ryo gutema?
Uburyo nyamukuru bwo gucamo ibice urutare mugihe cyo gutema ibiti byacitse ni ugusenyuka no kumenagura, kimwe nogukata amajwi manini no gucamo ibice, byunganirwa no gusya hejuru.Diyama ifite sisitemu ikora ikora nkigikoresho cyo guca.Igice cyacyo cyo gukata ni ahantu hasohokera, agace kaciwe kari imbere yuruhande, naho gusya ni kuruhande rwinyuma.Mugukata byihuse, ibice bya diyama bikora kubufasha bwa matrix.Mugihe cyo gutema amabuye, kuruhande rumwe, diyama ikorerwa igishushanyo, gucikamo ibice, no gutandukana bitewe nubushyuhe bwinshi buterwa no guterana amagambo;Kurundi ruhande, matrix yambarwa no guterana no gutwarwa namabuye nifu ya rock.Kubwibyo, ikibazo cyo guhuza n'imihindagurikire y'ibyuma n'amabuye ni ikibazo cyo kwambara hagati ya diyama na matrix.Ikiranga igikoresho gikora mubisanzwe nuko gutakaza diyama bihuye no kwambara matrix, kugumana diyama muburyo busanzwe bwo guca inyuma, haba gutandukana hakiri kare cyangwa gusya kwa diyama yoroshye kandi kunyerera, byemeza ko ingaruka zayo zo gusya zikoreshwa neza mugihe cyo gukora, bivamo diyama nyinshi kuba zacitse gato kandi zambaye.Niba imbaraga n'ingaruka zo kurwanya diyama yatoranijwe ari muke cyane, bizagushikana kuri "kogosha", kandi igihe cyo gukoresha igihe kizaba gito kandi passivation izaba ikomeye, ndetse no kubona ntibizagenda;Niba hatoranijwe imbaraga nyinshi cyane abrasive ibice byatoranijwe, guca inkombe zingingo zigaragara bizagaragara muburyo buboneye, bikavamo kwiyongera kwingufu zo kugabanya no kugabanya imikorere neza.
.Imyambarire yo kwambara yumubiri wicyuma iracyari hasi cyane, kandi ubuzima bwicyuma ni bugufi.
. seriveri irarengana, umuvuduko wo gukata uratinda, kandi biroroshye gutuma ikibaho cyaciwe kigwa, bigira ingaruka kumikorere.
(3) Iyo umuvuduko wo kwambara wa matrix uhwanye n'umuvuduko wo kwambara wa diyama, byerekana guhuza matrisa n'amabuye yaciwe.
