Mu gukata ibyuma, igikoresho cyo gutema cyahoze cyitwa amenyo yinganda zikora inganda, kandi imikorere yo kugabanya ibikoresho byo gutema nikimwe mubintu byingenzi byerekana umusaruro wacyo, igiciro cyumusaruro nubwiza bwo gutunganya. Kubwibyo, guhitamo neza ibikoresho byo gukata ibikoresho ni ngombwa.
Ibikoresho byerekana ibikoresho byo gukata igice.
By'umwihariko, guhitamo neza ibikoresho byibikoresho bigira ingaruka zikurikira:
Imashini itanga umusaruro, ibikoresho biramba, gukoresha ibikoresho nigiciro cyo gutunganya, gutunganya neza nubuziranenge bwubuso.
Mubisanzwe abantu bemeza ko ibikoresho byibikoresho birimo ibyuma bya karubone, ibyuma byifashishwa byuma, ibyuma byihuta cyane, ibyuma bikomeye, ububumbyi, cermets, diyama, nitride ya cubic boron, nibindi.
Cermet ni ibintu byinshi
Cermet
Cermet Ijambo ry'icyongereza cermet cyangwa ceramet igizwe na ceramic (ceramic) nicyuma (icyuma). Cermet ni ubwoko bwibintu byinshi, kandi ibisobanuro biratandukanye gato mubihe bitandukanye.
.
Komite y'umwuga y'Abanyamerika ASTM isobanura ko: ibikoresho bitavanze bigizwe n'ibyuma cyangwa ibivanze hamwe n'icyiciro kimwe cyangwa byinshi bya ceramic, icya nyuma kikaba kigizwe na 15% kugeza 85% by'igice cy'ubunini, kandi ku bushyuhe bwo kwitegura, Gukemura hagati ya ibyuma na ceramic ibyiciro ni bito.
Ibikoresho bikozwe mu byuma na ceramic ibikoresho fatizo bifite ibyiza bimwe byicyuma nububumbano, nkubukomere no kunama byabanje, hamwe nubushyuhe bwo hejuru, imbaraga nyinshi hamwe na okiside ya nyuma.
(2) Cermet ni karbide ya sima ifite ibice bikomeye bya titanium nkumubiri nyamukuru. Izina ry'icyongereza rya cermet, cermet, ni ihuriro ryamagambo abiri ceramic (ceramic) nicyuma (icyuma). Ti (C, N) yongera imbaraga zo kwambara kurwego, icyiciro cya kabiri gikomeye cyongera imbaraga zo kurwanya plastike, kandi ibirimo cobalt bigenzura ubukana. Cermets yongera imbaraga zo kwambara no kugabanya impengamiro yo gukomera kumurimo ugereranije na karbide yacumuye.
Kurundi ruhande, ifite kandi imbaraga nke zo kwikomeretsa hamwe no guhangana nubushyuhe bukabije bwumuriro. Cermets itandukanye nuruvange rukomeye kuberako ibice byabo bikomeye ari sisitemu ya WC. Cermets igizwe ahanini na Ti ishingiye kuri karbide na nitride, kandi byitwa na Ti ishingiye kuri sima ya karbide.
Cermets rusange kandi irimo ibinure bivangavanze, ibivanze bikomeye, hamwe nibikoresho bya diyama bifatanye. Icyiciro cya ceramic muri cermets ni oxyde cyangwa ivangavanga hamwe no gushonga cyane hamwe no gukomera gukomeye, kandi icyiciro cyicyuma ahanini ni ibintu byinzibacyuho hamwe nuruvange rwabo.
Cermet ni ubwoko bwibintu byinshi, kandi ibisobanuro biratandukanye gato mubihe bitandukanye.
Cermets ni ibikoresho byo gukata ibyuma
ibikoresho by'ingenzi
Cermets zirimo kuzamurwa
Mubisanzwe abantu bemeza ko ibikoresho byibikoresho birimo ibyuma bya karubone, ibyuma byifashishwa, ibyuma byihuta, ibyuma bya sima, cermet, ceramika, diyama, nitride ya cubic boron, nibindi.
Mu myaka ya za 1950, cermets ya TiC-Mo-Ni yakoreshejwe bwa mbere nk'ibikoresho by'ibikoresho byo guca ibyuma byihuse.
Ku ikubitiro cermets yashizwemo kuva TiC na nikel. Nubwo ifite imbaraga nyinshi nuburemere bukomeye ugereranije na karbide ya sima, ubukana bwayo burakennye.
Mu myaka ya za 70, cermets zishingiye kuri TiC-TiN, cermets zidafite nikel.
Iyi cermet igezweho, hamwe na titanium carboneitride Ti (C, N) ibice byingenzi, igice gito cyicyiciro cya kabiri gikomeye (Ti, Nb, W) (C, N) hamwe na tungsten-cobalt ikungahaye cyane, itezimbere icyuma The ubukana bwibumba byazamuye imikorere yabo yo guca, kandi kuva icyo gihe cermets zagiye zikoreshwa mugutezimbere ibikoresho.
Nubushuhe buhebuje bwo kurwanya ubushyuhe, kwambara no guhangana n’imiti, ibikoresho bya cermet byagaragaje ibyiza bitagereranywa mubijyanye no guca umuvuduko mwinshi no gukata ibikoresho bigoye kumashini.
Cermet + PVD itwikiriye kunoza kwambara
ejo hazaza
Gukoresha ibyuma bya cermet mubice bitandukanye bigenda byiyongera umunsi kumunsi, kandi ntagushidikanya ko inganda za cermet zizatera imbere kurushaho.
Cermets irashobora kandi gushirwa hamwe na PVD kugirango irusheho kunanirwa kwambara.
