Icyuma gipfundikijwe kiboneka hifashishijwe igipande cyicyuma cyoroshye kandi cyananiwe kwambara hejuru yicyuma cyihuta cyihuta (HSS) gifite imbaraga nimbaraga zikomeye muburyo bwo kubika imyuka. Nka bariyeri yubushyuhe hamwe nimbogamizi yimiti, igipfundikizo kigabanya ikwirakwizwa ryumuriro hamwe nubushakashatsi bwimiti hagati yicyuma cyakazi. Ifite uburebure bwo hejuru, kwihanganira kwambara neza, imiti ihamye, kurwanya ubushyuhe no kurwanya okiside, coefficente ntoya hamwe nubushyuhe bwumuriro. Ibiranga urwego rwo hasi, ubuzima bwicyuma gishobora kwiyongera inshuro nyinshi ugereranije nicyuma kidafunze mugihe cyo gutema. Kubwibyo, icyuma gitwikiriye cyahindutse ikimenyetso cyo gukata ibyuma bigezweho.
Ibyuma byihuta byihuta byuma, ibara ni ibara ryicyuma cyera, nicyuma kibonye kitavuwe, gukata ibyuma rusange bidafite ferrous, nkumuringa, aluminium nibindi.
Nitriding coating (umukara) VAPO nitriding itwikiriye ubushyuhe bwo hejuru ubushyuhe bwa okiside yubushyuhe, ibara ryirabura ryirabura, nyuma yimiti ya Fe3O4 ikozwe muburyo budasanzwe bwo kuvura ubushyuhe, hashyizweho urwego rwa oxyde (Fe3O4) hejuru, hamwe nubunini bwubunini oxyde ya oxyde igera kuri 5-10 Micron, ubukana bwubuso bugera kuri 800-900HV, coefficient de friction: 0,65, ubu bwoko bwikibabi gifite ubwiza bwubuso bwiza, bufasha kongera ubushobozi bwo kwisiga amavuta yicyuma, na phenomenon ko icyuma kibonye gifatanye nibikoresho birashobora kwirindwa kurwego runaka. Gukata ibikoresho rusange. Bitewe nubuhanga bukuze bwo gutunganya no gukora neza cyane, nibicuruzwa bikoreshwa cyane kumasoko.
Titanium nitride itwikiriye (zahabu) TIN Nyuma yo kuvura PVD nitrogen azitiriwe titanium, ubunini bwikariso ya blade igera kuri microne 2-4, ubukana bwayo ni nka 2200-2400HV, coefficient de frais: 0.55, kugabanya ubushyuhe: 520 ° C, ibi byabonye The icyuma gishobora kongera cyane igihe cyumurimo wicyuma. Kugirango ukoreshe byuzuye ibiranga, umuvuduko wo kugabanya ugomba kwiyongera kugirango ugaragaze agaciro kayo. Igikorwa nyamukuru cyiyi shitingi nugukora icyuma kirwanya gukata. Mugukata ibikoresho rusange, imikorere yacyo myiza irashobora kongera umuvuduko wo kugabanya no kugabanya igihombo.
Chromium Nitride Coating (Super Coating for short) CrN Iyi coating irwanya cyane cyane gufatira, kwangirika na okiside. Umubyimba wububiko bwikibabi ni microne 2-4, ubukana bwubuso: 1800HV, ubushyuhe bwo gukata buri munsi ya 700 ° C, kandi ibara ni imvi. Birasabwa cyane gukata umuringa na titanium, uburyo bwo gutwikira nta ngaruka bigira ku bidukikije. Birakwiye gukata umuringa, aluminiyumu nibindi bikoresho, hamwe nubucucike bukabije hamwe nubukomere bwo hejuru, hamwe nimpamvu yo hasi cyane mubitwikiriye.
Titanium aluminium nitride itwikiriye (ibara) TIALN Iyi ni igikoresho gishya cyo kurwanya-kwambara. Icyuma kibonerana cyavuwe hamwe na pVD ya pVD igeze kuri coefficient nkeya cyane. Ubuso bwacyo bugera kuri 3000-3300HV. coefficient de fraisation: 0.35, ubushyuhe bwa okiside: 450 ° C, ubu bwoko bwicyuma gishobora gutuma ubuso bwo gutema bugenda neza, kandi icyuma kibona cyihanganira kwambara. Birasabwa guca ibikoresho bifite umuvuduko mwinshi wo kugabanya no kugaburira kandi imbaraga zo gukata zirenga 800 N / mm2, nkibyuma bitagira umuyonga, nibindi, bikoreshwa mubihe bikomeye byakazi.
Aluminium titanium nitride (bita super A coating) ALTIN Iyi ni shyashya igizwe ninshi igizwe na anti-kwambara, ubunini bwiyi kote ni microne 2-4, ubukana bwubuso: 3500HV, coefficient de frais: 0.4, the kugabanya ubushyuhe Munsi ya 900 ° C, birasabwa gukoresha ibikoresho bifite umuvuduko mwinshi wo kugabanya no kugaburira umuvuduko no kugabanya imbaraga zingana zirenga 800 N / mm2 (nkibyuma bitagira umwanda), hanyuma ukabikoresha mubihe bikomeye byakazi nko gukata byumye. Bitewe no gukomera no guhagarara neza kumubiri wa aluminium titanium nitride ubwayo, icyuma kibona kirashobora kwangirika kandi gikwiriye gukata ibikoresho byose byuma. Bitewe na coefficient nkeya yo guterana hamwe nubushyuhe buke bwumuriro, birakwiriye cyane cyane gukata byumye kumuvuduko mwinshi nubushyuhe bwinshi.
Titanium Carbonitride Coating (Bronze) TICN Iyi ni coating ikwiranye nibisabwa cyane byo kurwanya kwambara. Basabwe gukata ibikoresho bifite imbaraga zingana hejuru ya 800 N / mm2. Ubunini bwikibiriti ni microne 3, coefficient de friction: 0.45, ubushyuhe bwa okiside: 875 ° C, kandi ubukana bwubuso ni 3300-3500HV. Ntabwo ikwiriye gukata ibyuma gusa nimbaraga nyinshi nkicyuma kitagira umwanda, ariko kandi irashobora gukoreshwa mugukata ibikoresho byoroshye nkibyuma, aluminiyumu, imiringa numuringa, nibindi. birakwiriye cyane cyane gukata kumuvuduko mwinshi nubushyuhe bwo hejuru gukata.
