PVD-a tlotsitsoeng - ke eng? Kopo PVD-barbotage ho indasteri e le lebetse

Morao-rao le lebetse ka indasteri e fana ka 'maraka e mengata e fapaneng dihlahiswa eo ba ka e utloisisa ka linako tse ling ho thata haholo. Ka proizvodnje ho litebelo Switzerland ba atisa ho sebelisa PVD-barbotage. Hore na ke eng, ha mong le e mong ea tsebang. Empa deposition holimo phetha karolo ea bohlokoa ho sireletsa sehlahiswa ho tloha mongobo le tse ling.

Ho phaella moo, ho na le mekhoa e meng ho ntlafatsa qhoaele hanyetsa le lihora tse ling tsa litšobotsi tse bona. Ena, ka mohlala, khauta plating, plating le nikele le Palladium, sputtering tšepe le ba bang. Ea se nang phihlelo motho thata ho fumana hore na bakeng sa hao tseo mokhoa o molemo ka ho fetisisa ebile le mekhoa e ka holimo ke e fapaneng le e mong le tse ling. A re ke re leka ho utloisisa.

PVD-a tlotsitsoeng - ke eng?

Lilemong tsa morao tjena, e pharaletseng e ratoang le lebetse ka ho nyanyatsoa ka holimo. Ke mang ea ke PVD-a tlotsitsoeng? ha e le eng?

Litsebi li hlokometse hore ho indasteri e lebetse mofuta hodimo ya barbotage e sebelisoa ka vacuo. Ke hore, ka sehlahisoa matlo nananosyat thaethaniamo nitride (ultrahard), e leng moo e tlotsitsoeng ka mokato otile haholo tsa khauta.

Hape, ho na le e 'ngoe lebitso le joalo mokhoa bakeng sa ho sireletsa lihora tse holim' ka PVD-barbotage. ha e le eng? Mokhoa ona barbotage e etsoa tlas'a khatello e phahameng ka lephaka e ka libomo, condensation, mouoane, sputtering metallization.

Ke ka lebaka la ho ao a mabeli e hlophisitsweng, lik'hemik'hale o ile a fumana hyperfine fafatsa ntle litšila leha e le efe.

Tshebediso ya lephaka deposition

mofuta ona wa deposition e sebediswa ho bopa holim'a lisebelisoa, likarolo, thepa barbotage ka boleloang tshebetso. Ka mohlala, ho hlahisa sebonoang liforeimi ka khauta kapa dihora le PVD-barbotage. deposition ena e na le thepa ea lintho tse latelang: ts'enyeho manganga, abrasion manganga, conductive, khoholeho ea mobu manganga, li sireletsang serameng, mokoallo,-ba khahlanong le khohlano.

E le thepa ea ho sputtering protrude lirafshoa tse kang thaethaniamo, tungsten, aluminium, molybdenum, nikele, tšepe, koporo, chromium graphite. Hape ka motsoako le theknoloji ile a phaella ka linako tse ling motho ea mafolofolo lik'hemik'hale khase. Mohlala, oksijene, naetrojene, kapa acetylene.

Sebelisa mokhoa holimo, lephaka deposition bahlahisi ba khona ho fumana marang-tšesaane barbotage botenya ho tloha 2 angstroms ho 2 microns. Litsebi ela hloko hore ka mor'a ya kopo ya PVD-a tlotsitsoeng sebetsa eketsehileng holim 'a sehlahiswa ha e sa hlokahala.

Se fapaneng le gilding PVD barbotage? Mekhoa bakeng sa ho etsa kopo ho nyanyatsoa sireletsang

Bobeli ba mokhoa ka holimo bakeng sa ho sireletsa ho tswa ho lihora tse mongobo ho pharaletseng sebelisoa indastering. Litsebi li bolela hore phapang ka sehloohong pakeng tsa ena le tloaelehileng tlotsitsoe ka khauta e feela e botenya ba sefaha sa letsoho sa khauta le tabeng le lebetse.

Re lokela ho hlokomela hore ho na le tšepe le PVD-barbotage - leeme kapa ka ho feletseng, o mosehla kapa o mosoeu. Ka watchcase ena barbotage o babatsehang metsi repellency le phahameng durability. The bokima jwa deposition ena ke ka mefuta e fapaneng ya 3 microns ho 20 microns.

Litsebi li bolela hore ho gilding qetellong ba hlakoloa. Ka selemo sa fokotswa botenya tsa khauta le lebetse, ho ea ka ya data karolelano ea ka 1 micron.

Hape ho na le mekhoa e meng ea ho sebelisa coatings sireletsang:

• Floor Palladium plating (ka nikele sebelisa hloeke tse nyenyane), e fana ka sehlahisoa se khanyang mmala tšoeu;
• Floor electroplating Palladium le nikele (fapaneng ho tswa ho mokhoa fetileng ka hore na e sebelisoa karolo e khōlō ea nikele);
• sputtering tšepe (watchcase tšoeu empa mebala lerootho);
• sputtering khauta (fana ka sehlahisoa mefuta eohle ea shades ea mosehla).

Har'a mekhoa mogote nyanyatsoa joalo thōko:

• mouoane ka laser toloki;
• elektroniki toloki le mouoane;
• lephaka selikalikoe mouoane;
• magnetron sputtering;
• Ion implantation.

Lintlha tse amang ho hanyetsa ba barbotage ea

barbotage durability haholo ho itšetlehile ka hore:

1. Liaparo entsoe ka letlalo. E ho fokotsa bophelo ba barbotage ke hoo e ka bang makhetlo a mabeli.
2. The acidity ea mofufutso batho, lihora mong'a. The matlo a ka qala ka mahlakoreng 'me ho tloha monyakong o ka morao, "corroded".
3. The bokima jwa barbotage e.
4. Latelwa le ditlhoko stringent theknoloji kopo.
5. Metal ho tlotsitsoeng (hore na bo a bakang mamarello).
6. Maemo a tshebediso ya sehlahiswa.

Main litšobotsi tse PVD-barbotage

The barbotage ka holimo e tšoauoa ka lintho tse latelang:

• hyperfine (1 ho 3 microns botenya);
• Ke ile ka ntle ho ba teng ha karolo ea litšila leha e le efe;
• Ho na le e phahameng durability;
• matla ka ho lekaneng;
• Ho sireletsa khahlanong le mengoapo.

PVD-a tlotsitsoeng le lebetse ka ke e 'ngoe ea litsela tse molemo ka ho fetisisa ho ba sireletsa. Thanks ho lihlahisoa ena tshebetso e ile ea eketseha ka vacuum cleaner deposition.
