Ikoranabuhanga ryo kuvura ubuso bwa PVD mu gusiga irangi rikomeye

Kubera ko inganda zigezweho zikomeje gusaba imikorere myiza y’ibice byazo, cyane cyane ibikora mu bihe bikomeye nko mu bushyuhe bwinshi, umuvuduko mwinshi, no gukururana gukomeye, ikoranabuhanga ryo gusiga rirushijeho kuba ingenzi cyane. Gukoresha irangi rikomeye bigira uruhare runini mu kongera igihe gihamye cy’ibikoresho, imikorere myiza y’imashini, no gukora neza kw’ibicuruzwa muri rusange. Ikoranabuhanga ryo gutunganya ubuso bwa PVD (Physical Vapor Deposition) ni ryo riri ku isonga mu guhanga udushya muri uru rwego, ritera imbere mu ikoranabuhanga ryo gusiga.

No.1. Ni iki gikorwa cya PVD?

Uburyo bwa PVD bukubiyemo gukoresha uburyo bufatika bwo guhindura ibikoresho byo gusiga biva mu buryo bukomeye cyangwa butemba bikajya mu buryo bwa gaze, hanyuma bikabishyira ku buso bwa substrate binyuze mu gusiga umwuka kugira ngo bikore irangi ringana, rikomeye kandi rirambye. Ugereranyije n'uburyo gakondo bwo gusiga umwuka w'ibinyabutabire (CVD), inyungu z'ibanze za PVD ziri mu bushobozi bwayo bwo gushyira irangi ku bushyuhe buri hasi, kugenzura neza ubugari n'imiterere y'irangi, hamwe n'imiterere yayo idahungabanya ibidukikije kandi ikoresha ingufu nke.

Ibyiza bya PVD mu gusiga irangi rikomeye ni 2
Bitewe n'ibyiza byayo bidasanzwe, ikoranabuhanga rya PVD rizwi cyane mu gukoresha irangi rikomeye, cyane cyane ahantu hasaba ubukana bwinshi, kudashira neza, no kudashira neza. Ibyiza by'ingenzi by'uburyo bwa PVD birimo:

1. Ubukomere buri hejuru cyane no kudashira
Irangi rikomeye rya PVD ryongera cyane ubukana bw'ibice. Mu gushyira ibikoresho nka TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), na CrN (Chromium Nitride), ubukana bw'irangi bushobora kugera kuri 25GPa–63GPa cyangwa hejuru. Izi rangi zikomeye zongerera ubushobozi bwo kudasaza, zigabanya kwangirika k'ubuso, zikongera ubukana bwo kudasaza, kandi zikongera igihe cyo gukoresha ibikoresho, ibumba, n'ibindi bice.

2. Ubudahangarwa bwiza cyane ku bushyuhe bwinshi
Imyambaro ya PVD irarwanya ubushyuhe bwinshi cyane, bigatuma iba nziza cyane ku bice bihura n'ubushyuhe bukabije ndetse no kwangirika cyane cyangwa kwangirika kw'imiti. Urugero, imyambaro ya TiAlN ntitanga ubukana budasanzwe gusa ahubwo inakomeza imiterere yayo mu bushyuhe bwinshi, bigatuma ikoreshwa cyane mu gukata no mu gushushanya ibikoresho bikoreshwa mu gucura ubushyuhe bwinshi.

3. Koreji yoroshye yo gukururana kugira ngo imashini zikore neza
Irangi rya PVD rifasha kugera ku miterere y’ingufu nke cyane, rigabanya ingufu n’ingufu z’ibikoresho, ibyo bikaba byongera imikorere myiza n’ubwiza bw’ubuso. Ibi ni ingirakamaro cyane cyane mu mikorere myiza no mu buryo bwo gukata vuba.

4. Irinda ibidukikije kandi ikora neza cyane
Ugereranyije n'uburyo busanzwe bwo gusiga irangi, uburyo bwo gusiga irangi bwa PVD ntibusaba imiti myinshi yangiza, bigatuma iba ikoranabuhanga ritangiza ibidukikije. Byongeye kandi, ibikoresho byo gusiga irangi bya PVD bikora neza cyane, bigatuma bishyirwa vuba mu buryo buhagije kugira ngo bihuze n'ibikenewe mu musaruro munini.

Ahantu ha 3 ho gukoresha PVD Hard Coating
Imashini za PVD zo gusiga irangi rikomeye zikoreshwa cyane mu nganda zikenera imikorere myiza y’ubuso. Zimwe mu ngingo z’ingenzi zikoreshwa harimo:

1. Ibikoresho byo Gukata n'Ibikoresho byo Gutunganya
Mu gukora ibikoresho n'ibihumyo, cyane cyane ku bikoresho byo gukata bihura n'ubushyuhe bwinshi n'ubushyuhe bwinshi, irangi rya PVD ryongera cyane ubushobozi bwo kudashira, kudashwanyagurika no gukomera. Irangi rya TiN rikunze gukoreshwa mu gucuragura ibikoresho, mu gukata imashini, no mu gutobora, mu gihe irangi rya TiAlN rikoreshwa cyane mu gukoresha irangi ryihuse, rituma imikorere y'ibikoresho irushaho kuba myiza kandi rigakomeza igihe kirekire.

2. Ibice bigize imodoka
Ku bice bya moteri y'imodoka nka silindiri, piston, na valve, irangi rikomeye rya PVD ritanga ubudahangarwa bwiza ku bushyuhe bwinshi no kudashira, rigabanya neza gukururana, rikongera igihe cyo kubaho kw'ibice, kandi rikongera imikorere y'imodoka muri rusange.

4. Intangiriro y'ibikoresho bya Zhenhua FMA0605 PVD Hard Coating
Ibyiza by'Ibikoresho
Gutunganya neza uduce duto twa arc; Ta-C coatings itanga umusaruro mwiza kandi ikora neza cyane.
Igira ubukana bwinshi cyane, irinda ubushyuhe bwinshi, ifite ubushobozi buke bwo gukururana, kandi irwanya ingese neza. Ubukana bungana na 25GPa–63GPa.

Iyi cathode ikoresha ikoranabuhanga rikoresha imiyoboro ibiri rihuza coil iri imbere n'ingufu zihoraho zo gufunga magnet, rikorana na sisitemu yo gushushanya ion hamwe n'icyuma gifite inguni nyinshi kugira ngo kigere ku buryo bunoze bwo gushyiramo ion.
Ifite umurambararo munini wa cathodic arc, utuma habaho ubukonje bwiza mu gihe cy'umuyaga mwinshi. Umuvuduko w'aho arc igenda ni wihuta, igipimo cya ionization kiri hejuru, kandi igipimo cyo gushyiramo ni cyihuta. Ibi bituma irangi rinini kandi ryoroshye rishobora kugabanya oxidation kandi rigatanga umusaruro mwiza mu bushyuhe bwinshi.
Ingano y'Ikoreshwa:
Ibikoresho bishobora gushyiramo AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, n'ibindi bikoresho bikomeye birwanya ubushyuhe bwinshi, byakoreshejwe cyane mu bikoresho byo gukata, ibikoresho byo gukata, ibikoresho by'imodoka, piston, n'ibindi bicuruzwa.
