PVD-ntekwasa - ihe ọ bụ? Ngwa PVD-mkpuchi na-eche nche ụlọ ọrụ

Modern nche ụlọ ọrụ na-enye ndị ahịa a dịgasị iche iche nke ngwaahịa na nke na-aghọta na ọ bụ mgbe ụfọdụ nnọọ ike. Ke imewe nke Switzerland ese na-eji PVD-mkpuchi. Ihe ọ bụ, ọ bụghị onye ọ bụla maara. Ma n'elu deposition ekere òkè dị mkpa na-echebe ngwaahịa si iru mmiri na ndị ọzọ.

Ke adianade do, e nwere ụzọ ndị ọzọ iji melite wear-eguzogide ma na ndị ọzọ awa nke àgwà ha. Nke a, ka ihe atụ, gold plating, plating na nickel na palladium, sputtering nchara na ndị ọzọ. Enweghị uche na onye siri ike ịhụ maka onwe gị na nke usoro bụ ihe kasị mma na n'elu ụzọ dị iche iche onye ọ bụla ọzọ. Ka anyị gbalịa ịghọta.

PVD-ntekwasa - ihe ọ bụ?

Na-adịbeghị anya, a sara mbara na-ewu ewu na nche na n'elu spraying. Ònye bụ PVD-ntekwasa? Gịnị ka ọ bụ?

Ndị ọkachamara achọpụtala na nche ụlọ ọrụ na n'elu ụdị mkpuchi na-etinyere na vacuo. Nke ahụ bụ, na ngwaahịa ụlọ nananosyat titanium nitride (ultrahard), nke na-ntekwasa na a nnọọ mkpa oyi akwa nke gold.

Ọzọkwa, e nwere ihe ọzọ designation dị otú ahụ usoro nke na-echebe n'elu awa ka PVD-mkpuchi. Gịnị ka ọ bụ? Nke a mkpuchi usoro nke a rụrụ n'okpuru elu nsogbu na a agụụ site bombardment, odide, evaporation, sputtering metallization.

Ọ bụ n'ihi na e hotara na mbụ chemical Filiks nwetara a hyperfine spraying enweghị ihe ọ bụla adịghị.

The ojiji nke agụụ deposition

Nke a na ụdị deposition na-eji ike n'elu ngwaọrụ, akụkụ, mkpuchi na ngwá ọtọ pụtara. Ka ihe atụ, na mmepụta nke ntem okpokolo agba na ọlaedo ma ọ bụ awa na PVD-mkpuchi. Nke a deposition nwere ndị na-esonụ Njirimara: corrosion na-eguzogide, abrasion na-eguzogide, conductive, ozize na-eguzogide, egbochi ihe, ihe mgbochi, mgbochi esemokwu.

Dị ka ihe na-sputtering protrude ọla dị ka titanium, tungsten, aluminum, molybdenum, nickel, ígwè, ọla kọpa, chromium, graphite. Ọzọkwa na a na nkà na ụzụ ngwakọta e kwukwara mgbe ụfọdụ n'ọrụ chemical gas. Ka ihe atụ, oxygen, nitrogen ma ọ bụ acetylene.

Iji n'elu usoro, agụụ deposition emepụta nwere ike inweta ultra-mkpa mkpuchi ọkpụrụkpụ site 2 angstroms 2 microns. Ndị ọkachamara kwuru na mgbe ngwa nke PVD-ntekwasa ọzọ nhazi elu nke ngwaahịa na-agaghịkwa adị mkpa.

Gịnị bụ dị iche iche si PVD mkpuchi gilding? Ụzọ n'itinye echebe spraying

Ma nke n'elu usoro n'ihi na ichebe si mmiri awa ọtụtụ-eji ụlọ ọrụ. Ọkachamara na-ekwu na isi ihe dị iche n'etiti a na a ot plated na gold bụ nnọọ ọkpụrụkpụ nke gold mgbaaka na-eche nche ikpe.

Ọ ga-kwuru na e nwere a nchara na PVD-mkpuchi - ele mmadụ anya n'ihu ma ọ bụ zuru ezu, odo ma ọ bụ na-acha ọcha. Na nke a na mkpuchi watchcase nwere magburu onwe mmiri repellency na elu anwụ ngwa ngwa. Ọkpụrụkpụ nke a deposition bụ na nso nke 3 microns 20 microns.

Ọkachamara na-ekwu na gilding emecha ehichapu ya. N'afọ nke belata ọkpụrụkpụ nke gold na-eche nche, dị ka nkezi data nke banyere 1 micron.

Ọzọkwa e nwere ụzọ ndị ọzọ nke itinye echebe coatings:

• Ft palladium plating (na nickel eji a obere adịghị ọcha), nke na-enye ngwaahịa a na-egbuke egbuke acha ọcha na agba;
• Ft electroplating palladium na nickel (dị iche iche si aga usoro na e na-etinyere a ukwuu pasent nke nickel);
• sputtering ígwè (watchcase ọcha ma dull agba);
• sputtering gold (enye ngwaahịa nile di iche iche nke shades nke odo).

N'etiti thermal spraying ụzọ ndị dị otú ahụ dịpụrụ adịpụ:

• evaporation laser ákwà;
• electronic doo evaporation;
• agụụ aak evaporation;
• magnetron sputtering;
• ion nkunye.

Ihe na-emetụta ndị na-eguzogide nke mkpuchi

mkpuchi anwụ ngwa ngwa ukwu-adabere:

1. Uwe mere nke akpụkpọ anụ. Ọ na-ebelata ndụ nke mkpuchi bụ mkpokọta ugboro abụọ.
2. The acidity nke mmadụ ajirija, nwe awa. The ụlọ nwere ike ịmalite ke n'akụkụ, sikwa n'azụ na ụzọ, "corroded".
3. Ọkpụrụkpụ nke mkpuchi.
4. Nnabata ya na tiri chọrọ nke ngwa technology.
5. Metal ka ntekwasa (ma ọ na-akpata adhesion).
6. Ọnọdụ nke ojiji nke ngwaahịa.

Main e ji mara PVD-mkpuchi

The n'elu mkpuchi e ji ndị na-esonụ atụmatụ:
