PVD-rufi - abin da yake da shi? Aikace-aikace PVD-shafi a agogon masana'antu

Modern agogon masana'antu offers da kasuwar mai fadi da kewayon kayayyakin da ake so a fahimta shi ne wani lokacin quite wuya. A yi na Swiss watches sau da yawa amfani PVD-shafi. Abin da shi ne, ba kowa da kowa ya sani. Amma sama shaida taka muhimmiyar rawa a kare samfurin daga zafi da kuma more.

Bugu da kari, akwai wasu hanyoyi don inganta lalacewa juriya da kuma sauran sa'o'i na halaye. Wannan, misali, zinariya plating, annabcin da nickel da palladium, sputtering karfe da sauransu. Saba da mutum wuya a gano da kanka wanda Hanyar ne mafi kyau da sama hanyoyin su ne daban-daban daga juna. Bari mu yi kokarin fahimtar.

PVD-rufi - abin da yake da shi?

A cikin 'yan shekaru, wani m rare agogon tare da sama spraying. Wane ne PVD-rufi? Mene ne wannan?

Masana sun lura da cewa, a cikin agogon masana'antu sama da irin shafi ne amfani a vacuo. Wannan shi ne, a cikin samfurin gidaje nananosyat titanium nitride (ultrahard), a kan wanda aka mai rufi da sosai bakin ciki Layer na zinariya.

Har ila yau, akwai wani nadi irin wannan hanya domin kare surface sa'o'i kamar yadda PVD-shafi. Mene ne wannan? Wannan shafi Hanyar wanda yana da za'ayi a karkashin babban matsin a wani wuri da bombardment, sandaro, danshin, sputtering metallization.

Shi ne saboda da waccan mujalla da muka sunadarai matakai samu wani hyperfine spraying ba tare da wani impurities.

A amfani da injin shaida

Wannan irin shaida da ake amfani da su haifar a farfajiya na kayan aikin, sassa, shafi kayan aiki da aikin abinda. Alal misali, samar da spectacle kangon da zinariya ko sa'o'i da PVD-shafi. Wannan shaida yana da da wadannan Properties: lalata-resistant, abrasion-resistant, conductive, yashewa-resistant, insulating, shãmaki, anti-gogayya.

Kamar yadda kayan sputtering protrude karafa kamar titanium, tungsten, aluminum, molybdenum, nickel, da baƙin ƙarfe, jan, chromium, graphite. Har ila yau a wani fasaha cakuda da aka kara lokaci-lokaci aiki sinadaran gas. Alal misali, oxygen, nitrogen, ko acetylene.

Amfani da sama hanya, injin shaida masana'antun iya samu ultra-bakin ciki shafi kauri daga 2 angstroms zuwa 2 microns. Masana sun lura cewa bayan da aikace-aikace na PVD-rufi ƙarin aiki surface na samfurin da aka ba da ake bukata.

Mene ne daban-daban daga PVD shafi gilding? Hanyar da ake ji da m spraying

Dukansu na sama hanya domin kare daga danshi sa'o'i yadu a yi amfani masana'antu. Masana sun ce wannan babban bambanci tsakanin wannan da wata al'ada dalaye su da zinariya ne kawai da kauri da zinariya munduwa da agogon hali.

Ya kamata a lura cewa akwai wani karfe da PVD-shafi - m ko complete, rawaya ko farar fata. Tare da wannan shafi watchcase yana da kyau kwarai ruwa repellency kuma high karko. A kauri daga wannan shaida ne a cikin kewayon 3 microns zuwa 20 microns.

Masana sun ce cewa gilding ƙarshe sharewa. A cikin shekara ta rage kauri daga cikin zinariya a kan watch, bisa ga talakawan data na game da 1 micron.

Har ila yau, akwai wasu hanyoyin da ake ji m coatings:

• Floor palladium plating (tare da nickel amfani da wani kananan najasa), wanda ya ba da samfurin wani haske da farin launi.
• Floor electroplating palladium da nickel (daban-daban daga baya Hanyar in cewa akwai aka yi amfani da mafi yawan nickel).
• sputtering karfe (watchcase fari amma maras ban sha'awa launuka).
• sputtering zinariya (bada samfurin iri iri na inuwõyinta suna kusa, yellow).

Daga cikin thermal spraying hanyoyin irin ware:

• danshin Laser masaƙa.
• lantarki katako danshin.
• injin baka danshin.
• magnetron sputtering.
• ion kafawa.

Dalilai da shafi da juriya na shafi

shafi karko da yawa dogara a kan:

1. Tufafi da aka yi da fata. Ya rage rai na shafi ne kamar sau biyu.
2. A acidity na mutum gumi, mai hours. The gidaje iya fara a tarnaƙi, kuma daga raya kofa, "corroded".
3. A kauri daga cikin rufi.
4. Yarda da stringent bukatun na aikace-aikace fasaha.
5. Metal da za a mai rufi (ko shi sa mannewa).
6. Yanayin amfani na samfur.

Main halaye PVD-shafi

The sama rufi ne halin da wadannan siffofin:

• hyperfine (1 zuwa 3 microns kauri).
• Yana sanya ba tare da kasancewar wani ɓangare na wani impurities.
• Yana yana da babban karko.
• karfi da isa.
• Yana kare da scratches.

PVD-rufi agogon ne daya daga cikin mafi kyau hanyoyin da za a kare su. Godiya ga wannan wasan kwaikwayon kayayyakin ƙãra injin shaida.
