PVD-dahaarka leh - waa maxay? Codsiga PVD-daahan in industry gaadhka

warshadaha watch Modern bixisaa suuqa tiro balaadhan oo ah wax soo saarka, kuwaas oo si ay u fahmaan mararka qaarkood waa kuwo ku adag. In saaridda qayli Swiss inta badan isticmaalaan PVD-daahan. Waa maxay, qof kasta oo aan og yahay. Laakiin dhigaalka kor ku ciyaaraa door muhiim ah ka ilaalinta wax soo saarka ka soo qoyaan iyo ka badan.

Intaa waxaa dheer, waxaa jira habab kale si loo hagaajiyo iska caabin ah ay xirtaan iyo saacadaha kale ee sifooyinka ay. Tani, tusaale ahaan, dahaadhay dahab, dahaadhay la nickel iyo palladium, steel sputtering iyo kuwa kale. qofka u hureen adag tahay si aad u ogaato naftaada qaabka ugu fiican iyo hababka kor ku xusan waxa ay ka soo kasta oo kale oo kala duwan. Aan isku dayno si ay u fahmaan.

PVD-dahaarka leh - waa maxay?

Sanadihii la soo dhaafay, a watch caan ballaadhan la xereen ee kor ku xusan. Yaa PVD-dahaarka leh? Waa maxay?

Khubarada ayaa sheegay in warshadaha gaadhka nooca kor ku xusan ee daahan waxaa laga codsadaa in vacuo. Taasi waa, in nitride titanium nananosyat guryaha sheyga (ultrahard), in ka badan oo la dahaarka leh kula lakabka ah oo aad u khafiif ah oo dahab ah.

Sidoo kale, waxaa jira magaca kale hab sida ilaalinta saacadood dusha sare sida PVD-daahan. Waa maxay? Habka daahan oo waxaa lagu fuliyaa cadaadis sare ee vacuum ah by duqeymo, uumiga, uumi, metallization sputtering.

Waxaa sabab u ah habka kiimikada sheegnay helay hyperfine ah ku xereen aan nijaasta ahaa kasta.

Isticmaalka dhigaalka vacuum

Noocan ah dhigaalka waxaa loo isticmaalaa in la abuuro dushiisa of qalab, qaybo, qalabka daahan la tusinaysaa functional. Tusaale ahaan, wax soo saarka ee lanooga hindisaa dahab ama saacadaha la PVD-daahan. dhigaalka waxa uu leeyahay sifooyinka soo socda: daxalka u adkaysta, abrasion u adkaysta, tabinta, nabaad-adkaysi, qalabada, ooday, anti-xoqidda.

Sida qalabka si sputtering taag biraha sida titanium, tungsten, aluminium, molybdenum, nickel, birta, copper, chromium, graphite. Sidoo kale in isku dar ah farsamada lagu daray gaaska kiimikada mararka firfircoon. Tusaale ahaan, oxygen, nitrogen ama alxamaad.

Isticmaalka habka kor ku xusan, saarayaasha dhigaalka vacuum awoodaan in ay helaan oo dhumucdiisuna waxay daahan aalladda khafiif ah ka 2 angstroms 2 microns. Khubarada la soco in ka dib markii codsiga ah ee PVD-dahaarka leh dusha processing dheeraad ah ee alaabta waxaa mar dambe loo baahan yahay.

Waa maxay kala duwan ka gilding daahan PVD ah? Hababka codsan xereen ilaalinta

Labada habka kor ku xusan yahay ilaalinta ka saacadood qoyaan si ballaaran loo adeegsado warshadaha. Khubarada ayaa sheegaya in farqiga ugu weyn ee u dhexeeya this iyo caadiga ah dahaadhay dahab waa uun dhumucda jijin dahabkii iyo kiiska gaadhka.

Waa in la ogaadaa in ay jirto bir leh PVD-daahan - qayb ahaan ama gebi, huruud ah ama caddaan. Iyada oo watchcase daahan this ayaa repellency biyo aad u fiican iyo cimri dherer sare. dhumucda dhigaalka tani waa kala duwan ee 3 microns 20 microns.

Khubarada ayaa sheegaya in gilding ayaa ugu danbeyn tirtirayaa. Oo sannadda oo dhumucdiisuna waxay hoos on gaadhka dahab ah, sida ku cad xogta celcelis ahaan qiyaastii 1 micron.

Sidoo kale waxaa jira habab kale oo codsanaya blaastiigga ilaaliya:

• dahaadhay palladium Floor (la nickel isticmaalaya nijaasta daahiriya yar), taas oo ku siinayaa sheyga midab cadcad oo dhaldhalaalaya,
• Floor electroplating palladium iyo nickel (ka duwan habka hore in ay jiraan waxaa laga codsadaa boqolkiiba weyn ee nickel);
• sputtering steel (white watchcase laakiin midabada ugu maqlaan);
• sputtering dahab ah (oo ku siinayaa sheyga cayn kasta ah oo midabo kala ah huruud ah).

Ka mid ah hababka ku xereen kaamerada sida go'doonsan:

• uumi dogob laser;
• uumi dogob elektaroonik ah;
• vacuum uumi ARC,
• sputtering magnetron;
• ra'iyi tallaalmid.

Arrimaha saameynaya iska caabin ah ee daahan

cimri dherer daahan la taaban karo waxay ku xiran tahay:

1. Dharka laga sameeyey maqaar. Waxay yaraynaysaa nolosha daahan waa qiyaastii laba jeer.
2. ashitada ee dhididka aadanaha, saacadaha milkiilaha. guryaha ayaa laga yaabaa in dhinacyada iyo albaabka danbe, "mirdheen".
3. dhumucda daahan.
4. Compliance leh shuruudaha adag ee technology codsiga.
5. Birta waa in la mariyaa (haddii ay tahay keena Amda).
6. Shuruudaha isticmaalka sheyga.

sifooyinka Main PVD-daahan

daahan ee kor ku xusan waxaa lagu gartaa sifooyinka soo socda:

• hyperfine (1 ilaa 3 microns oo dhumucdiisuna waxay);
• Waxa aan joogitaanka qayb ka mid ah waxyaalihii nijaasta kasta;
• Waxay leedahay cimri dherer sare;
• xoog ku filan;
• Wuxuu ka hortagaa xagashada.

PVD-dahaarka leh watch waa mid ka mid ah hababka ugu fiican ee iyaga la ilaaliyo. Thanks to this waxyaabaha waxqabadka kordhay dhigaalka vacuum.
