PVD-zvemapuranga - chii? Application PVD-unhani Nenguva indasitiri

Modern yokurinda indasitiri inopa mumusika zvakawanda zvigadzirwa umo kunzwisisa zviri dzimwe nguva zvakaoma. In anogadzira zvinhu kwenguva Swiss dzinowanzotaura PVD-unhani. Chii, haasi munhu wose anoziva. Asi pamusoro deposition inoita basa rinokosha okudzivirira chigadzirwa kubva mwando zvakawanda.

Uyezve, pane dzimwe nzira kuvandudza kusakara nemishonga nezvimwe maawa hwounhu dzavo. Izvi Somuenzaniso, ndarama yakanamirwa pamifananidzo, ra pamwe nickel uye palladium, sputtering simbi uye nevamwe. Ruzivo munhu zvakaoma kuwana zvichenjerere iro nzira ndiwo akanakisisa uye pamusoro nzira vakasiyana mumwe. Ngatiedzei kunzwisisa.

PVD-zvemapuranga - chii?

Mumakore achangopfuura, munoremekedza dzakakurumbira makarinda pamusoro apa spraying. Ndiani PVD-zvemapuranga? Chii?

Nyanzvi dzakaona kuti mune varindi indasitiri pamusoro mhando unhani rinoshandisirwa mu vacuüm it. Ndiko, ari chigadzirwa redzimba nananosyat titanium nitride (ultrahard), pamusoro izvo zvinenge zvakazara nhete chaizvo rukoko ndarama.

Uyewo, pane mumwe rokuti nzira idzodzo okudzivirira pamusoro maawa sezvo PVD-unhani. Chii? Izvi bemhapemha nzira iyo rinoitwa pasi kumusoro kumanikidzwa ari Vacuum kubudikidza bombardment, condensation, kwemvura, sputtering metallization.

Zviri nokuda chambotaurwa nezvacho zvemakemikari pezvakaitwa vakawana hyperfine spraying isina tsvina.

Kushandiswa Vacuum deposition

Izvi mhando deposition rinoshandiswa rokusika panyika maturusi, zvikamu, unhani midziyo pamwe dzichipfekeka kunanga. Somuenzaniso, kugadzirwa kwechishamiso runotaura nendarama kana maawa pamwe PVD-unhani. napylenie Izvi zvinotevera ehupfumi: ngura nemishonga, abrasion nemishonga, conductive, kukurwa kwevhu nemishonga, insulating, mhinganidzo, Anti kukweshera.

Sezvo zvinhu sputtering protrude nesimbi akadai titanium, tungsten, aruminiyamu, molybdenum, nickel, simbi, mhangura, chromium, graphite. Uyewo mune muzvigadzirwa musanganiswa chakawedzerwa neapo kushingaira nemakemikari gasi. Somuenzaniso, okisijeni, senitrogen kana acetylene.

Kushandisa nzira pamusoro apa, Vacuum deposition vagadziri vanokwanisa kuwana Ultra-matetetete unhani ukobvu kubva 2 angstroms 2 microns. Nyanzvi dzinoti pashure kushanda PVD-zvemapuranga mamwe kubudiswa pose chigadzirwa hakuchisina kunodiwa.

Chii chakasiyana PVD unhani gilding? Nzira kushandisa unodzivirira spraying

Vose nzira pamusoro kudzivirira kubva kuunyoro maawa zvinowanzoshandiswa indasitiri. Nyanzvi dzinoti huru musiyano pakati ichi uye kwakajairika nendarama rinongova pakukora nendarama ndarira uye varindi nyaya.

Zvinofanira kucherechedzwa kuti pane simbi pamwe PVD-unhani - zvishomanana kana zvakakwana, yellow kana chena. With ichi bemhapemha watchcase ane wakanaka mvura repellency uye yakakwirira mukurumari. Ukobvu deposition ichi iri kuwanda 3 microns 20 microns.

Nyanzvi vanoti gilding pakupedzisira zvapera. Mugore kwakaderedza pakukora ndarama takarinda, maererano avhareji Data vanenge 1 micron.

Uyewo kune dzimwe nzira kushandisa anodzivirira coatings:

• Floor palladium yakanamirwa pamifananidzo (pamwe nickel uchishandisa tsvina diki), aunopiwa chigadzirwa chena ruvara rakajeka;
• Floor electroplating palladium uye nickel (akasiyana rapfuura nzira iyoyo pane rinoshandisirwa mukuru chikamu nickel);
• sputtering simbi (watchcase chena asi pakunzwa mavara);
• sputtering goridhe (rinopa chigadzirwa siyana noruvara yellow).

Pakati chafariz spraying nzira dzakadaro dzoga:

• Kusimuka kwemvura Laser danda;
• zvemagetsi danda kwemvura;
• Vacuum chinhu chakakombama kwemvura;
• magnetron sputtering;
• Ion muchibereko.

Zvinhu kukanganisa kurwisa of unhani

bemhapemha mukurumari zvikuru pakuti:

1. Clothing chedebwe. It akazoita upenyu unhani ndiyo inenge kaviri.
2. The acidity kuti ziya kwevanhu, muridzi maawa. Dzimba angatanga panhivi neshure musuo, "ngura".
3. Pakukora yacho unhani.
4. Zvaidiwa inoomesera zvinodiwa chikumbiro michina.
5. Metal kuti zvemapuranga (kana chinokonzera adhesion).
6. Zvemupiro kushandisa chigadzirwa.

Main Unhu PVD-unhani

The pamusoro bemhapemha kunoratidzwa anotevera zvinhu:

• hyperfine (1 kusvika 3 microns ukobvu);
• It pasina kuvapo chikamu chero netsvina akaita;
• It ane mukuru mukurumari;
• simba zvakakwana;
• Inochengetedza pamusoro anokwenya.

PVD-zvemapuranga yokurinda ndeimwe yenzira kuvadzivirira. Nemhaka iyi waivako zvigadzirwa kwakawedzera Vacuum deposition.
