Njengoba ukukhiqiza kwesimanje kuqhubeka kufuna ukusebenza okuphezulu ezingxenyeni ezithile, ikakhulukazi lezo ezisebenza ngaphansi kwezimo ezibucayi njengamazinga okushisa aphezulu, umfutho ophakeme, nokungqubuzana okuqinile, ubuchwepheshe bokumboza buye babaluleka kakhulu. Ukusetshenziswa kwezingubo eziqinile kudlala indima ebalulekile ekuthuthukiseni ukuqina kwamathuluzi, ukunemba komshini, kanye nokusebenza komkhiqizo kukonke. Ubuchwepheshe bokwelashwa kwe-PVD (Physical Vapor Deposition) buhamba phambili ekwenziweni okusha kulo mkhakha, okuqhubekisela phambili intuthuko kubuchwepheshe bokumboza.
No.1 Iyini Inqubo Ye-PVD?
Inqubo ye-PVD ihilela ukusebenzisa izindlela ezibonakalayo ukuze kuguqule izinto zokumboza zisuke esimweni esiqinile noma eziwuketshezi zibe yisimo segesi, bese zifakwa endaweni engaphansi komhlaba ngokufaka umhwamuko ukuze zakhe ukunamathela okufanayo, okuqinile, nokuqinile. Uma kuqhathaniswa ne-chemical chemical vapor deposition (CVD), izinzuzo eziyinhloko ze-PVD zisemandleni ayo okufaka ama-coatings emazingeni okushisa aphansi, ukulawula ngokunembile ukujiya nokubunjwa kwayo, kanye nemvelo yayo evumelana nemvelo nokonga amandla.
No.2 Izinzuzo ze-PVD ku-Hard Coatings
Ngenxa yezinzuzo zayo eziyingqayizivele, ubuchwepheshe be-PVD buqashelwa kabanzi ekusetshenzisweni kwezingubo eziqinile, ikakhulukazi ezindaweni ezidinga ubulukhuni obuphezulu, ukumelana nokugqoka okuhle kakhulu, nokumelana nokugqwala okuphakeme. Izinzuzo ezibalulekile zenqubo ye-PVD zifaka:
1. Ubulukhuni obuphezulu kakhulu kanye Nokumelana Nokugqoka
Izingubo eziqinile ze-PVD zithuthukisa kakhulu ubulukhuni bengxenye. Ngokufaka izinto ezifana ne-TiN (Titanium Nitride), i-TiAlN (i-Titanium Aluminium Nitride), ne-CrN (Chromium Nitride), ukuqina kokunamathela bungafinyelela ku-25GPa–63GPa noma ngaphezulu. Lezi zingubo eziqinile zithuthukisa ngempumelelo ukumelana nokugqokwa, zinciphise ukuhuzuka kwendawo, zikhulise ukumelana ne-oxidation, futhi zandise impilo yesevisi yamathuluzi, isikhunta, nezinye izakhi.
2. Ukumelana Nokushisa Okuhle Kakhulu
Izingubo ze-PVD zibonisa ukumelana nezinga lokushisa okuphezulu okuvelele, okuzenza zilungele izingxenye ezingaphansi kwamazinga okushisa adlulele kanye nokungqubuzana okuphezulu noma ukugqwala kwamakhemikhali. Isibonelo, izimbotshana ze-TiAlN azinikezi nje kuphela ubulukhuni obukhethekile kodwa futhi zigcina ukuqina kwesakhiwo emazingeni okushisa aphakeme, okuwenza asetshenziswe kabanzi kumathuluzi okusika nokubumba kwezinhlelo zokusebenza zemishini ezisezingeni eliphezulu.
3. I-Low Friction Coefficient Yokusebenza Kahle Kwemishini
Izembatho ze-PVD zisiza ukufeza ama-coefficients aphansi kakhulu wokungqubuzana, ukunciphisa ukungqubuzana nokuguga, okuthuthukisa ukusebenza kahle kwemishini kanye nekhwalithi yendawo. Lokhu kuzuzisa kakhulu ekwenzeni imishini enembile kanye nezinqubo zokusika ngesivinini esikhulu.
4. Ayinobungane Imvelo Futhi Isebenza Kakhulu
Uma kuqhathaniswa nezindlela zokugqoka zendabuko, inqubo ye-PVD ayidingi inani elikhulu lamakhemikhali ayingozi, okwenza kube ubuchwepheshe obunobungani bemvelo. Ukwengeza, imishini yokuhlanganisa ye-PVD isebenza kahle kakhulu, ivumela ukufakwa ngokushesha ukuze kuhlangatshezwane nezidingo zokukhiqiza ezinkulu.
No.3 Izinkambu Zokusebenza Ze-PVD Hard Coating
Imishini ye-PVD Hard Coating yezingubo eziqinile isetshenziswa kabanzi ezimbonini ezidinga ukusebenza okuphezulu kwendawo. Ezinye izindawo ezibalulekile zohlelo lokusebenza zifaka:
1. Amathuluzi Okusika kanye Nesikhunta
Ekwenziweni kwamathuluzi nesikhunta, ikakhulukazi amathuluzi okusika achayeke emazingeni okushisa aphezulu kanye nokungqubuzana, izimbotshana ze-PVD zithuthukisa kakhulu ukumelana nokugqokwa, ukumelana nokugqwala, nobulukhuni. Izembatho ze-TiN zivame ukusetshenziswa ekuguquleni amathuluzi, izisiki zokugaya, kanye nokubhoboza, kuyilapho ukumbozwa kwe-TiAlN kusetshenziswa kakhulu ezinhlelweni zokusika ngesivinini esikhulu, kuthuthukisa kakhulu ukusebenza kahle kwamathuluzi nempilo yesevisi.
2. Izingxenye Zezimoto
Ezingxenyeni zenjini yezimoto njengamasilinda, amaphistoni, namavalvu, ama-PVD aqinile anikeza ukumelana nezinga lokushisa eliphezulu nokumelana nokugqokwa, ehlisa ngempumelelo ukungqubuzana, inwebe isikhathi sokuphila kwengxenye, futhi athuthukisa ukusebenza kwemoto iyonke.
4. Ukwethulwa kwe-Zhenhua FMA0605 PVD Izisetshenziswa Zokuhlanganisa Okuqinile
Izinsiza Zezinsiza
Ukuhlunga okusebenzayo kwama-arc macro-particles; Izingubo ze-Ta-C zinikeza kokubili ukusebenza kahle okuphezulu nokusebenza okuphezulu.
Ifinyelela ubulukhuni obuphezulu kakhulu, ama-superhards amelana nokushisa okuphezulu, i-coefficient ephansi yokungqubuzana, nokumelana nokugqwala okuhle kakhulu. Ubulukhuni obumaphakathi bufinyelela ku-25GPa–63GPa.
I-cathode isebenzisa ubuchwepheshe obunamadrayivu amabili obuhlanganisa ikhoyili emile ngaphambili kanye nokunqwabelanisa kazibuthe unomphela, esebenza eduze kwesistimu yokunamathisela i-ion kanye nokulungiswa kwama-engeli amaningi okuntathu-ntathu ukuze kuzuzwe ukubekwa kahle.
Ifakwe i-cathodic arc enobubanzi obukhulu, eqinisekisa izindawo zokupholisa ezinhle kakhulu ngaphansi kwezimo eziphezulu zamanje. Isivinini sokunyakaza kwendawo ye-arc siyashesha, izinga le-ionization liphezulu, futhi izinga lokubeka liyashesha. Lokhu kuvumela ukufakwa kwezingubo eziminyene nezibushelelezi ezinokumelana ne-oxidation ephakeme nokusebenza kwezinga lokushisa eliphezulu.
Ububanzi bohlelo lokusebenza:
Izinto ezisetshenziswayo zingafaka i-AlTiN, i-AlCrN, i-TiCrAlN, i-TiAlSiN, i-CrN, nezinye izigqoko eziqinile ezimelana nokushisa okuphezulu, ezisetshenziswe kabanzi ekubunjweni, amathuluzi okusika, ama-punch, izingxenye zezimoto, amaphistoni, neminye imikhiqizo.
