Sezvo kugadzirwa kwemazuva ano kuri kuramba kuchida kushanda kwepamusoro kubva kuzvikamu, kunyanya izvo zvinoshanda pasi pemamiriro akanyanya senge tembiricha yakakwira, kudzvanywa kwakanyanya, uye kupokana kwakasimba, tekinoroji yekupfeka yave kuwedzera kukosha. Iko kushandiswa kwemachira akaomarara kunoita basa rakakosha mukusimudzira kusimba kwechishandiso, kunyatsoita machining, uye kuita kwese kwechigadzirwa. PVD (Physical Vapor Deposition) tekinoroji yekurapa kwepamusoro iri pamberi pehunyanzvi mundima iyi, ichifambisa kufambira mberi muhunyanzvi hwekupfeka.
Nha.1 Chii chinonzi PVD Process?
Maitiro ePVD anosanganisira kushandisa nzira dzepanyama kushandura zvinhu zvekunamira kubva panzvimbo yakasimba kana yemvura kuita gasi, wozodziisa pane iyo substrate pamusoro kuburikidza nekuisa mhute kuita yunifomu, yakaoma, uye yakasimba coating. Kuenzaniswa neyechinyakare chemikemikari vapor deposition (CVD), iwo mabhenefiti ekutanga ePVD ari mukukwanisa kwayo kuisa machira patembiricha yakaderera, kunyatso kudzora ukobvu hwekufukidzira uye kuumbwa, uye hunhu hwayo hune hushamwari uye husina simba.
No.2 Zvakanakira PVD mune Hard Coatings
Nekuda kwemabhenefiti ayo akasiyana, tekinoroji yePVD inozivikanwa zvakanyanya mukushandiswa kwemajasi akaomarara, kunyanya munzvimbo dzinoda kuomarara kwepamusoro, kupfeka kwakanakisa kuramba, uye kwepamusoro corrosion kuramba. Mabhenefiti akakosha ePVD maitiro anosanganisira:
1. Ultra-yakakwirira Kuoma uye Wear Resistance
PVD yakaoma coatings inosimudzira zvakanyanya chikamu kuoma. Nekuisa zvinhu zvakaita seTiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), uye CrN (Chromium Nitride), kuoma kwejasi kunogona kusvika 25GPa-63GPa kana kutokwira. Aya mabhanhire akaomarara anovandudza kupfeka kuramba, kuderedza abrasion yepasi, kuwedzera oxidation kuramba, uye kuwedzera hupenyu hwesevhisi yezvishandiso, mold, uye zvimwe zvinhu.
2. Yakanakisa High-Temperature Resistance
PVD coatings inoratidza yakasarudzika yekupisa tembiricha, ichiita kuti ive yakakodzera kune zvikamu zviri pasi pekupisa kwakanyanya uye kukweshera kwakanyanya kana kemikari corrosion. Semuyenzaniso, machira eTiAlN haangope kuomarara kwakasiyana chete asiwo anochengetedza kugadzikana kwechimiro patembiricha yakakwira, zvichiita kuti ashandiswe zvakanyanya mukucheka maturusi uye molds epamusoro-tembiricha machining application.
3. Low Friction Coefficient for Improved Machining Efficiency
PVD machira anobatsira kuwana ekupedzisira-yakaderera friction coefficients, kuderedza kukweshera kwezvinhu uye kupfeka, izvo zvinosimudzira machining kunyatsoshanda uye pamusoro pemhando. Izvi zvinonyanya kubatsira kune chaiyo machining uye high-speed yekucheka maitiro.
4. Kushamwaridzana Nezvakatipoteredza uye Kunyatsoshanda
Kuenzaniswa nemaitiro echinyakare ekupfekedza, maitiro ePVD haadi kuwanda kwemakemikari anokuvadza, zvichiita kuti ive tekinoroji inochengetedza zvakatipoteredza. Pamusoro pezvo, PVD yekuputira michina inoshanda nepamusoro-soro, ichigonesa kukurumidza kuiswa kuti isangane nehukuru-hukuru hwekugadzira zvinodiwa.
No.3 Application Fields yePVD Hard Coating
PVD Hard Coating michina yeakaomarara machira anoshandiswa zvakanyanya mumaindasitiri anoda epamusoro pepamusoro pekuita. Dzimwe nzvimbo dzinokosha dzekushandisa dzinosanganisira:
1. Kucheka Zvishandiso uye Molds
Mukugadzira maturusi uye mold, kunyanya yekucheka maturusi akafumurwa kune yakakwira tembiricha uye kukweshana, PVD machira anowedzera zvakanyanya kupfeka kuramba, corrosion resistance, uye kuoma. TiN coatings inowanzoshandiswa mukushandura maturusi, milling cutters, uye drills, nepo TiAlN coatings inoshandiswa zvakanyanya mu-high-speed cuting applications, inovandudza zvikuru kucheka kwezvishandiso uye hupenyu hwebasa.
2. Zvigadzirwa zveMotokari
Kune zvikamu zveinjini zvemotokari zvakaita semasilinda, mapistoni, uye mavharuvhu, PVD yakaoma machira inopa yakanakisa-yepamusoro-tembiricha kuramba uye kupfeka kuramba, zvinobudirira kudzikisa kukweshera, kuwedzera chikamu chehupenyu, uye nekunatsiridza kuita kwese kwemotokari.
4. Kutanga kweZhenhua FMA0605 PVD Hard Coating Equipment
Zvishandiso Zvakanakira
Kubudirira kusefa kwearc macro-particles; Ta-C coatings inopa zvese zviri zviviri kushanda kwepamusoro uye kuita kwepamusoro.
Inowana kuomarara kwepamusoro-soro, yakakwirira-yekudzivirira-inodzivirira machira makuru, yakaderera friction coefficient, uye yakanakisa corrosion resistance. Avhareji yekuoma inosvika 25GPa–63GPa.
Iyo cathode inotora tekinoroji yedhiraivha inosanganisa kumberi-yakamira coil uye yekusingaperi magineti stacking, ichishanda padivi peiyo ion etching system uye matatu-dimensional akawanda-ekona gadziriso kuti iwane dhizaini inoshanda.
Yakashongedzerwa nehombe-diameter cathodic arc, iyo inovimbisa yakanakisa kutonhora zvivakwa pasi pemamiriro azvino. Iyo arc spot yekufamba kumhanya inokurumidza, ionization rate yakakwira, uye deposition rate inokurumidza. Izvi zvinogonesa kuiswa kwe denser uye yakapfava machira ane yepamusoro oxidation kuramba uye yakakwirira-tembiricha kuita.
Application Scope:
Midziyo yacho inogona kuisa AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, uye mamwe machira epamusoro-anodzivirira kupisa, ayo akaiswa zvakanyanya muforoma, maturusi ekucheka, zvibhakera, zvinhu zvemotokari, piston, uye zvimwe zvigadzirwa.
