2. Kupaka ufa
Kupaka ufa ndi njira yowuma yomaliza yomwe imaphatikizapo kugwiritsa ntchito ufa wouma pamwamba pa chitsulo cha electrostatically ndiyeno nkuchiza mu uvuni kuti chikhale chokhazikika, chokongoletsera.Ufawu umapangidwa ndi utomoni, pigment, ndi zowonjezera, ndipo umabwera mumitundu ndi mawonekedwe osiyanasiyana.
3. Chemical Blackening/ Black okusayidi
Chemical blackening, yomwe imadziwikanso kuti black oxide, ndi njira yomwe imasintha pamwamba pa chitsulo kukhala wosanjikiza wachitsulo wakuda wachitsulo, womwe umapereka kumalizidwa kokongoletsa ndikuwonjezera kukana kwa dzimbiri.Njirayi imaphatikizapo kumiza gawo lachitsulo mu njira yothetsera mankhwala yomwe imakhudzidwa ndi pamwamba kuti ipange wosanjikiza wakuda wa oxide.
4. Electropolishing
Electropolishing ndi njira ya electrochemical yomwe imachotsa chitsulo chochepa kwambiri pamwamba pa chitsulo, zomwe zimapangitsa kuti pakhale kutha, kowala.Njirayi imaphatikizapo kumiza gawo lachitsulo mu njira ya electrolyte ndikugwiritsa ntchito magetsi kuti asungunuke pamwamba pazitsulo.
5. Kuphulika kwa mchenga
Kuphulika kwa mchenga ndi njira yomwe imaphatikizapo kuthamangitsira zinthu zonyezimira pa liwiro lapamwamba pamwamba pa chitsulocho kuti zichotse zonyansa, zosalala zosalala, ndi kupanga mapeto ake.Zida zowononga zimatha kukhala mchenga, mikanda yagalasi, kapena mitundu ina ya media.
6. Kuphulitsa mikanda
Kuphulika kwa mikanda kumawonjezera yunifolomu ya matte kapena satin pamwamba pa gawo lopangidwa ndi makina, kuchotsa zizindikiro za zida.Izi zimagwiritsidwa ntchito makamaka pazowoneka ndipo zimabwera m'magalasi angapo osiyanasiyana omwe amawonetsa kukula kwa ma pellets a bombarding.grit yathu yokhazikika ndi #120.
| Chofunikira | Kufotokozera | Chitsanzo cha gawo lophulika mkanda |
| Grit | #120 |

7. Kujambula
Kupenta kumaphatikizapo kupaka utoto wamadzimadzi pamwamba pa chitsulo chachitsulo kuti ukhale wokongoletsera komanso kuti usawonongeke.Njirayi imaphatikizapo kukonzekera pamwamba pa gawolo, kugwiritsa ntchito primer, ndiyeno kupaka utoto pogwiritsa ntchito mfuti ya spray kapena njira ina yogwiritsira ntchito.
8. QPQ
QPQ (Quench-Polish-Quench) ndi njira yochizira pamwamba yomwe imagwiritsidwa ntchito pazigawo zamakina za CNC kuti iwonjezere kukana, kukana dzimbiri, komanso kuuma.Njira ya QPQ imaphatikizapo masitepe angapo omwe amasintha pamwamba pa gawolo kuti apange wosanjikiza wolimba, wosavala.
Njira ya QPQ imayamba ndikuyeretsa gawo la makina a CNC kuti muchotse zonyansa zilizonse.Gawolo limayikidwa mu bafa lamchere lomwe lili ndi njira yapadera yozimitsa, yomwe imakhala ndi nayitrogeni, sodium nitrate, ndi mankhwala ena.Gawoli limatenthedwa kutentha kwapakati pa 500-570 ° C ndiyeno limazimitsidwa mofulumira mu njira yothetsera vutoli, zomwe zimapangitsa kuti pakhale mankhwala opangidwa pamwamba pa gawolo.
Panthawi yozimitsa, nayitrogeni amafalikira pamwamba pa gawolo ndikuchitapo kanthu ndi chitsulocho kuti apange wosanjikiza wolimba, wosavala.Makulidwe a wosanjikiza wapawiri amatha kusiyanasiyana kutengera momwe amagwiritsidwira ntchito, koma nthawi zambiri amakhala pakati pa 5-20 microns wandiweyani.
Pambuyo pozimitsa, mbaliyo imapukutidwa kuti ichotse khwimbi kapena zosokoneza pamtunda.Njira yopukutira iyi ndiyofunikira chifukwa imachotsa zolakwika zilizonse kapena zopindika zomwe zimayambitsidwa ndi njira yozimitsa, kuonetsetsa kuti pakhale malo osalala komanso ofanana.
Gawolo limazimitsidwanso mumchere wosambitsa mchere, womwe umathandiza kupsya mtima wosanjikiza ndi kukonza makina ake.Njira yomaliza yozimitsa iyi imaperekanso kukana kwa dzimbiri pamwamba pa gawolo.
Zotsatira za njira ya QPQ ndi yolimba, yosavala pamwamba pa gawo la makina a CNC, ndi kukana kwa dzimbiri komanso kukhazikika bwino.QPQ imagwiritsidwa ntchito kwambiri pamapulogalamu apamwamba kwambiri monga mfuti, zida zamagalimoto, ndi zida zamafakitale.
9. Gasi nitriding
Gesi nitriding ndi njira yochizira pamwamba yomwe imagwiritsidwa ntchito m'magawo omata a CNC kuonjezera kuuma kwa pamwamba, kukana kuvala, komanso kutopa.Njirayi imaphatikizapo kuyika gawolo ku mpweya wochuluka wa nayitrogeni pa kutentha kwakukulu, zomwe zimapangitsa kuti nayitrojeni azifalikira pamwamba pa gawolo ndikupanga wosanjikiza wolimba wa nitride.
Njira yopangira mpweya wa nitriding imayamba ndikuyeretsa gawo la makina a CNC kuti muchotse zonyansa zilizonse kapena zonyansa.Gawolo limayikidwa mu ng'anjo yomwe imadzazidwa ndi mpweya wochuluka wa nayitrogeni, nthawi zambiri ammonia kapena nayitrogeni, ndikutenthetsa kutentha kwapakati pa 480-580 ° C.Gawoli limagwira pa kutentha uku kwa maola angapo, kulola kuti nayitrogeni ifalikire pamwamba pa gawolo ndikuchitapo kanthu kuti apange wosanjikiza wolimba wa nitride.
Makulidwe a nitride wosanjikiza amatha kusiyanasiyana kutengera momwe amagwiritsidwira ntchito komanso kapangidwe kazinthu zomwe zikuthandizidwa.Komabe, nitride wosanjikiza nthawi zambiri umachokera ku 0.1 mpaka 0.5 mm mu makulidwe.
Ubwino wa nitriding wa gasi umaphatikizanso kulimba kwapamwamba, kukana kuvala, komanso mphamvu ya kutopa.Zimawonjezeranso kukana kwa gawoli kuti zisawonongeke komanso kutentha kwambiri kwa okosijeni.Njirayi ndi yothandiza kwambiri pazigawo zamakina za CNC zomwe zimatha kung'ambika kwambiri, monga magiya, mayendedwe, ndi zida zina zomwe zimagwira ntchito ponyamula katundu wambiri.
Gesi nitriding imagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, zakuthambo, ndi zida.Amagwiritsidwanso ntchito zosiyanasiyana ntchito zina, kuphatikizapo kudula zida, jekeseni nkhungu, ndi zipangizo zachipatala.
10. Nitrocarburizing
Nitrocarburizing ndi njira yochizira pamwamba yomwe imagwiritsidwa ntchito pazigawo zamakina za CNC kukulitsa kuuma kwa pamwamba, kukana kuvala, komanso kutopa.Njirayi imaphatikizapo kuwonetsa gawolo ku mpweya wa nayitrogeni ndi mpweya wochuluka wa carbon pa kutentha kwakukulu, zomwe zimapangitsa kuti nayitrogeni ndi kaboni azifalikira pamwamba pa gawolo ndikupanga wosanjikiza wolimba wa nitrocarburized.
Njira ya nitrocarburizing imayamba ndikuyeretsa gawo la makina a CNC kuti muchotse zonyansa zilizonse.Gawoli limayikidwa mu ng'anjo yomwe imadzazidwa ndi mpweya wosakaniza wa ammonia ndi hydrocarbon, nthawi zambiri propane kapena gasi wachilengedwe, ndikutenthetsa kutentha kwapakati pa 520-580 ° C.Gawoli limachitika pa kutentha uku kwa maola angapo, kulola kuti nayitrogeni ndi kaboni azifalikira pamwamba pa gawolo ndikuchitapo kanthu kuti apange wosanjikiza wolimba wa nitrocarburized.
Makulidwe a nitrocarburized wosanjikiza amatha kusiyanasiyana kutengera kagwiritsidwe ntchito komanso kapangidwe kazinthu zomwe zikuthandizidwa.Komabe, wosanjikiza wa nitrocarburized nthawi zambiri umachokera ku 0.1 mpaka 0.5 mm mu makulidwe.
Ubwino wa nitrocarburizing umaphatikizanso kulimba kwapamwamba, kukana kuvala, komanso mphamvu ya kutopa.Zimawonjezeranso kukana kwa gawoli kuti zisawonongeke komanso kutentha kwambiri kwa okosijeni.Njirayi ndi yothandiza kwambiri pazigawo zamakina za CNC zomwe zimatha kung'ambika kwambiri, monga magiya, mayendedwe, ndi zida zina zomwe zimagwira ntchito ponyamula katundu wambiri.
Nitrocarburizing imagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, mlengalenga, ndi zida.Amagwiritsidwanso ntchito zosiyanasiyana ntchito zina, kuphatikizapo kudula zida, jekeseni nkhungu, ndi zipangizo zachipatala.
11. Chithandizo cha Kutentha
Kuchiza kutentha ndi njira yomwe imaphatikizapo kutenthetsa gawo lachitsulo ku kutentha kwapadera ndiyeno kuziziritsa mwadongosolo kuti likhale lolimba, monga kuuma kapena kulimba.Njirayi imatha kuphatikizira kutsitsa, kuzimitsa, kutenthetsa, kapena kukhazikika.
Ndikofunikira kusankha yoyenera padziko mankhwala anu CNC machined zitsulo gawo potengera zofunika zenizeni ndi kutsiriza ankafuna.Katswiri atha kukuthandizani kusankha chithandizo chabwino kwambiri cha pulogalamu yanu.
