Tsamba lopaka utoto limapezedwa pokutira chitsulo chopyapyala chokhala ndi kukana kwabwino kwachitsulo pamwamba pa chitsulo chothamanga kwambiri (HSS) chokhala ndi mphamvu zabwino komanso kulimba mwa njira yoyika nthunzi. Monga chotchinga chamafuta ndi chotchinga chamankhwala, zokutira zimachepetsa kufalikira kwamafuta ndi machitidwe amankhwala pakati pa tsamba la macheka ndi chogwirira ntchito. Lili ndi kuuma kwapamwamba kwambiri, kukana kuvala bwino, kukhazikika kwa mankhwala, kukana kutentha ndi kukana kwa okosijeni, kusakanikirana kwazing'ono ndi matenthedwe matenthedwe. Makhalidwe otsika, moyo wa tsamba la macheka ukhoza kuonjezedwa kangapo poyerekeza ndi tsamba la macheka pa nthawi yodula. Choncho, yokutidwa macheka tsamba wakhala chizindikiro cha masiku kudula macheka masamba.
Full mkulu-liwiro zitsulo macheka tsamba, mtundu ndi woyera zitsulo mtundu, ndi tsamba macheka popanda ❖ kuyanika mankhwala, kudula ambiri zitsulo sanali achitsulo, monga mkuwa, zotayidwa ndi zina zotero.
Nitriding ❖ kuyanika (wakuda) VAPO nitriding ❖ kuyanika kutentha kutentha makutidwe ndi okosijeni mankhwala, mtundu mdima wakuda, pambuyo mankhwala chinthu Fe3O4 ndi pansi yeniyeni kutentha mankhwala, ndi okusayidi wosanjikiza (Fe3O4) aumbike padziko, ndi makulidwe a oxide wosanjikiza ndi za 5-10 Micron, pamwamba kuuma ndi za 800-900HV, mikangano koyenera: 0,65, mtundu wa macheka tsamba ali ndi kusalala bwino pamwamba, amene amathandiza kumapangitsanso kudzikonda lubricating luso la macheka tsamba, ndi chodabwitsa. kuti tsamba la macheka limamatidwa ndi zinthuzo litha kupewedwa pamlingo wina. Pakuti kudula wamba zipangizo. Chifukwa cha ukadaulo wake wokhwima wokonza komanso magwiridwe antchito okwera mtengo, ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pamsika.
Titaniyamu nitride zokutira (golide) TIN Pambuyo pa PVD nitrogen titaniyamu mankhwala, makulidwe a macheka blade zokutira ndi pafupifupi 2-4 microns, pamwamba kulimba kwake ndi pafupifupi 2200-2400HV, mikangano koyenera: 0.55, kudula kutentha: 520 ° C, anawona tsamba la macheka limatha kuwonjezera nthawi yautumiki wa tsamba la macheka. Kuti agwiritse ntchito bwino mawonekedwe ake, liwiro lodulira liyenera kuwonjezeka kuti liwonetse mtengo wake. Ntchito yayikulu ya zokutira izi ndikupangitsa kuti tsamba la macheka likhale lolimba podula. Pakuti kudula zipangizo wamba, ntchito zake zabwino kwambiri angathe kuonjezera kudula liwiro ndi kuchepetsa imfa.
Chromium Nitride Coating (Super Coating mwachidule) CrN Chophimba ichi chimalimbana makamaka ndi kumatira, dzimbiri ndi okosijeni. Makulidwe okutira a tsamba la macheka ndi ma microns 2-4, kuuma kwapamtunda: 1800HV, kutentha kodulira ndikotsika kuposa 700 ° C, ndipo mtundu wake ndi wachitsulo wotuwa. Amalimbikitsidwa kwambiri kudula mkuwa ndi titaniyamu, njira yophimbayo ilibe mphamvu pa chilengedwe. Oyenera kudula mkuwa, aluminiyamu ndi zida zina, zokhala ndi kachulukidwe kwambiri zokutira komanso kulimba kwapamtunda, komanso kugunda kotsika kwambiri pakati pa zokutira zonse.
Titanium aluminiyamu nitride zokutira (mtundu) TIALN Ichi ndi chosanjikiza chatsopano chosanjikiza choletsa kuvala. Tsamba la macheka lomwe limapangidwa ndi zokutira za PVD zamitundu ingapo lakwanitsa kugundana kocheperako. Kulimba kwake pamwamba ndi za 3000-3300HV. friction coefficient: 0.35, kutentha kwa oxidation: 450 ° C, mtundu woterewu wa macheka umapangitsa kuti malo odulirawo azikhala osalala kwambiri, ndipo tsamba la macheka silimamva kuvala. Ndi bwino kudula zipangizo ndi liwiro lachangu kudula ndi kudyetsa liwiro ndi kudula kumakoka mphamvu kuposa 800 N/mm2, monga Stainless chitsulo, etc., ntchito pansi makamaka nkhanza ntchito.
Aluminiyamu titaniyamu nitride ❖ kuyanika (otchedwa super A ❖ kuyanika) ALTIN Ichi ndi chopaka chambiri chosanjikiza chotsutsana ndi kuvala, makulidwe a zokutira uku ndi ma microns 2-4, kuuma kwapamtunda: 3500HV, koyefit ya kukangana: 0.4, the kudula kutentha Pansi pa 900 ° C, tikulimbikitsidwa kugwiritsa ntchito zipangizo zomwe zili ndi liwiro lalikulu lodula ndi liwiro la kudyetsa ndi kudula mphamvu zowonongeka zopitirira 800 N / mm2 (monga chitsulo chosapanga dzimbiri), ndikuzigwiritsa ntchito pansi pazifukwa zovuta kwambiri monga kudula kouma. Chifukwa cha kulimba komanso kukhazikika kwakuthupi kwa aluminium titaniyamu nitride yokutira yokha, tsamba la macheka silitha kuvala komanso loyenera kudula zida zonse zachitsulo. Chifukwa cha kugunda kwake kocheperako komanso kutsika kwamafuta otsika, ndikoyenera kwambiri kudula kowuma pa liwiro lalikulu komanso kutentha kwambiri.
Titanium Carbonitride Coating (Bronze) TICN Ichi ndi chotchingira choyenera kutengera zofunikira kwambiri zoletsa kuvala. Analimbikitsa kudula zipangizo ndi kumakokedwa mphamvu pa 800 N/mm2. Makulidwe a zokutira ndi 3 ma microns, coefficient of friction: 0.45, oxidation kutentha: 875 ° C, ndi kuuma kwa pamwamba ndi pafupifupi 3300-3500HV. Sikoyenera kokha kudula zitsulo zokhala ndi mphamvu zambiri monga zitsulo zosapanga dzimbiri, komanso zingagwiritsidwe ntchito podula zipangizo zofewa monga chitsulo chosungunula, aloyi ya aluminiyamu, mkuwa ndi mkuwa, ndi zina zotero. ndizoyenera makamaka kudula pa liwiro lapamwamba komanso kutentha kwakukulu kouma.
