Waa maxay sababta biinanka dhaldhalaalkaagu si fudud u libdhaan? Daah-furka Geedi-socodka "Ilaalinta Saddexda Korantada" ee La-yaqaanka ah ee Warshadaha

Dunida caadooyinka caadooyinka, sii yaraanaya ayaa weli madax-xanuun joogto ah u ah iibsadayaal badan - haddii midabada firfircoon ee calaamadaha dhaldhalaalka ay lumiyaan dhalaal wakhti ka dib ama meelaha biraha ah waxay yeeshaan midab aan fiicnayn. Weligaa ma la yaabtay sababta calaamadaha qaar ay u muuqdaan sannado halka kuwa kalena ay si degdeg ah u libdhaan? Qarsoodi inta badan waxay ku jirtaa farsamada gacanta oo la iska indho-tiray: habka "ilaalinta korantada ee saddex-laha ah", kaas oo noqday kala-duwanaansho muhiim ah oo loogu talagalay soosaarayaasha calaamadaha sare.

Dilemma Fading: Dhibicda Xanuunka Guud ee Warshadaha

Dhumintu waa ka badan tahay arrin bilicda uun; waxay si toos ah u saamaysaa cimriga iyo qiimaha la dareemay ee calaamaduhu. Sahannada suuqyadu waxay muujinayaan in 68% iibsadayaashu ay la kulmeen calaamado sii yaraanaya 6 bilood gudahood, oo leh arrimo ay ka mid yihiin daxalka dhididka, soo-gaadhista iftiinka qorraxda, iyo xidhashada maalinlaha ah ee inta badan lagu eedeeyo. Si kastaba ha ahaatee, in yar ayaa garwaaqsan in sababta asaasiga ahi ay inta badan ka soo baxdo ilaalinta korantada oo aan ku filnayn.

 

"Calaamadaha summada shirkadu waxay bilaabeen inay caajisaan 3 bilood oo keliya ka dib," waxaa ka cawday maamulaha wax iibsiga ee shirkad tignoolajiyadeed. "Waxaan u maleynay inay sabab u tahay dhaldhalaalka tayada hooseeya, laakiin dhibaatada dhabta ah waxay ahayd lakabka khafiifka ah ee khafiifka ah." Kiisaska noocaan oo kale ah waa kuwo baahsan, oo muujinaya asymmetry-ga macluumaadka warshadaha ee ku saabsan tignoolajiyada korantada.

Ilaalinta Saddexda Korantada: Sida ay u shaqeyso

1. Lakabka koowaad: Substrate nikel ee iska caabinta daxalka

Nidaamku wuxuu ku bilaabmaa 5-8μm nikkel oo dahaadhaysa lakabka hoose. Iska caabbinta daxalka ee wanaagsan ee Nickel waxay samaysaa caqabad ka hortagta qoyaanka iyo kiimikooyinka. Si ka duwan dahaadh hal lakab ah oo raqiis ah (badanaa dhumucdiisuna tahay 1-2μm), lakabkan aasaasiga ah oo keliya ayaa u adkeysan kara 500+ saacadood oo tijaabo ah buufin milix ah, oo aad uga badan heerka warshadaha ee 200 saacadood.

 

Aragtida Farsamada: Artigiftsmedals waxay isticmaashaa caanaha nikkel-sulfur alloy-ga iska leh, taas oo kordhinaysa adkaanta dusha sare ilaa 500-600 HV (adkeydka Vickers), kaas oo 30% ka adkaysi badan marka loo eego dahaadhka nikkel-ka caadiga ah.

2. Lakabka Dhexe: Copper ee Midabka Midabka

Lakab naxaas ah oo 3-5μm ah ayaa markaa la mariyaa, isagoo u adeegaya sidii dhexdhexaad midab-sixiye. Dusha siman ee Copper waxay buuxisaa daldaloolo-yar oo ku jira substrate-ka birta, iyadoo hubinaysa in lakabyada midabka xiga ay si isku mid ah ugu dheggan yihiin. Tani waxay muhiim u tahay calaamadaha dhaldhalaalka-la'aanteed dhexda naxaasta ah, midabada midabku waxay dhex geli karaan jeexjeexyada birta, taasoo keenta inay si siman u dhumaan.

 

Daraasadda Kiis: Kooxda ciyaaraha ee caadadooda caadadooda ee isticmaalaya saddex-jibbaaran waxay muujisay 80% kala duwanaansho midab yar ka dib 1 sano marka la barbar dhigo alaabada hal lakab ee tartamayaasha, sida lagu xaqiijiyay tijaabooyinka spectrophotometer.

3. Lakabka dusha sare: Dahaarka birta ah ee qaaliga ah ee luster

Lakabka kama dambaysta ah - oo u dhexeeya 1-3μm oo dahab, qalin ah, ama rhodium ah - wuxuu ku darayaa soo jiidashada quruxda iyo cimri dhererka labadaba. Lakabkaan waxaa lagu dhejiyay tignoolajiyada hadda jirta ee garaaca wadnaha, taasoo abuuraysa qaab dhismeed cufan oo ka hortagaya xagashada iyo oksaydhka.

 

  • Dahaarka Dahabka: 24K Dahab Dahab ah oo leh wax dahab ah oo saafi ah ≥99.9%, ilaalinta dhalaalka xitaa 10+ sano ka dib.
  • Rhodium Plating: Dahaar cad oo 5 jeer ka adag platinum, oo ku habboon baahiyaha wasakhaysan (tusaale, badda ama deegaanka caafimaadka).

Qiimaha Ka Danbeya Tayada: Maxay Tahay Sababta Saddex-Piling

Qaar badan oo ka mid ah calaamadaha jaban ee suuqa ayaa isticmaala "flash plating"-lakab khafiif ah (≤1μm) kaas oo bakhtiya toddobaadyo gudahood. Taa beddelkeeda, koronto-samaynta saddex-geesoodka ah waxay ku lug leedahay:

 

  • 3x Waqtiga Wax Soo Saarka Dheeraadka ah: Lakab kastaa wuxuu u baahan yahay qubaysyo dahaadhan oo madaxbannaan iyo kontoroolka pH ee saxda ah.
  • 20x Qiimaha Qalabka Sare: Biraha qaaliga ah sida naxaasta korantada iyo 99.99% dahab saafi ah ayaa la isticmaalaa.
  • QC Adag: Dufc walba waxa la mariyaa 10+ tijaabooyin, oo ay ku jiraan buufinta milixda, naaxinta, iyo hubinta xabagta.

 

"Iyadoo calaamadayada saddex-geeska ah ee saddex-geesoodka ah ay qiimihiisu yihiin 25-30% ka badan, waxay sii jiraan 10 jeer ka badan," ayuu yiri maamule farsamo ee Artigiftsmedals. "Noocyada, waa maalgelinta aqoonsigooda muuqaalka ah ee cimri dhererka."

Si xikmad leh u doorta: Hagaha Iibsadaha ee Calaamadaha Ka-hortagga Qarsoon

  1. Weydiiso Tilmaamaha Dajinta: Ku adkeyso xogta qoran ee ku saabsan dhumucda lakabka iyo alaabta.
  2. Samee Tijaabo Fudud: Ku xoq calaamadda suufka suufka ah ee lagu rusheeyey aalkolo-ku dhejinta raqiis ah waxay ka tagi doontaa haraaga midabka.
  3. Hubi Shahaadooyinka Warshadaha: Raadi ISO 9227 (buufin milix ah) iyo u hoggaansanaanta ASTM B117.

 

Marka shakhsiyaynta iyo aqoonsiga summada ay u koraan muhimadda, baahida loo qabo calaamado waara ayaa kor u kacaya. Habka ilaalinta korantada ee saddex-geesoodka ah ma aha oo kaliya horumar tignoolajiyadeed; waxay markhaati u tahay farsamada gacanta ee da'da wax-soo-saarka guud-in la hubiyo in calaamaddaadu ay ahaanayso astaan ​​firfircoon, oo aan ahayn qalab dagdag ah.
