Mphamvu ya diamondi pamwamba ❖ kuyanika mankhwala

1. Lingaliro la zokutira pamwamba pa diamondi

Daimondi pamwamba ❖ kuyanika, amatanthauza ntchito pamwamba mankhwala ukadaulo pa diamondi pamwamba yokutidwa ndi wosanjikiza zinthu zina filimu. Monga ❖ kuyanika zakuthupi, kawirikawiri zitsulo (kuphatikizapo aloyi), monga mkuwa, faifi tambala, titaniyamu, molybdenum, mkuwa malata titaniyamu aloyi, faifi tambala cobalt aloyi, faifi tambala cobalt phosphorous aloyi, etc.; ❖ kuyanika zinthu zinanso zinthu sanali zitsulo, monga ziwiya zadothi, titaniyamu carbide, titaniyamu ammonia ndi mankhwala ena refractory zolimba. Pamene zinthu zokutira zili zitsulo, zimatha kutchedwanso diamondi pamwamba zitsulo.

Cholinga cha zokutira pamwamba ndi kupatsa diamondi particles wapadera thupi ndi mankhwala katundu, kuti kusintha ntchito yawo. Mwachitsanzo, ntchito pamwamba- TACHIMATA diamondi abrasive kupanga utomoni gudumu akupera, moyo wake utumiki kwambiri yaitali.

2. Gulu la njira yokutira pamwamba

Industrial pamwamba mankhwala njira gulu onani chithunzi m'munsimu, amene kwenikweni ntchito mu wapamwamba zovuta abrasive pamwamba ❖ kuyanika njira, otchuka kwambiri makamaka chonyowa mankhwala plating (palibe electrolysis plating) ndi plating, plating youma (amatchedwanso vacuum plating) mu mankhwala nthunzi mafunsidwe (CVD) ndi thupi nthunzi mafunsidwe (PVD), kuphatikizapo ntchito vacuum ufa sinter zitsulo.

 

3. Kupaka makulidwe kumayimira njira

Chifukwa ❖ kuyanika makulidwe a pamwamba diamondi abrasive particles n'kovuta kudziwa mwachindunji, nthawi zambiri anasonyeza kulemera (%). Pali njira ziwiri zowonetsera kulemera:

Kumene A ndiko kulemera (%); G1 ndiye kulemera kwake kopera musanayambe plating; G2 ndiye kulemera kwa nsabwe; G ndiye kulemera konse (G=G1 + G2)

4. Mmene diamondi pamwamba ❖ kuyanika pa diamondi chida ntchito

Mu chida cha diamondi chopangidwa ndi Fe, Cu, Co ndi Ni, tinthu tating'ono ta diamondi titha kulumikizidwa mwamakina m'matrix chifukwa chosagwirizana ndi mankhwala omwe amamangirira pamwambapa komanso kusowa kwa mawonekedwe. Pansi pa mphamvu yopera, pamene tinthu tating'onoting'ono ta diamondi timapezeka ku gawo lalikulu, chitsulo cha thupi la tayala chidzataya tinthu tating'ono ta diamondi ndikugwa pachokha, chomwe chimachepetsa moyo wautumiki ndi kukonza bwino kwa zida za diamondi, ndipo zotsatira zogaya za diamondi sizingaseweredwe mokwanira. Chifukwa chake, pamwamba pa diamondi ili ndi mawonekedwe azitsulo, omwe amatha kusintha moyo wautumiki komanso kukonza bwino kwa zida za diamondi. Chofunikira chake ndikupanga zinthu zomangirira monga Ti kapena aloyi yake yokutidwa mwachindunji pamwamba pa diamondi, kupyolera mu kutentha ndi kutentha kutentha, kotero kuti diamondi pamwamba pake imapanga yunifolomu yogwirizanitsa mankhwala.
Mwa ❖ kuyanika diamondi akupera particles, zimene ❖ kuyanika ndi diamondi kuti metalize pamwamba diamondi. Komano, metallized diamondi pamwamba ndi zitsulo thupi kumanga wothandizila pakati zitsulo zitsulo osakaniza zitsulo, Choncho, ❖ kuyanika mankhwala a diamondi kwa ozizira kuthamanga madzi sintering ndi otentha olimba gawo sintering ali applicability lonse, kotero tayala thupi aloyi kwa diamondi akupera chimanga kuphatikiza kuchuluka, kuchepetsa chida cha diamondi ntchito akupera, kusintha moyo utumiki ndi dzuwa zida diamondi.

5. Kodi ntchito zazikuluzikulu zochizira diamondi ndi ziti?

1. Kupititsa patsogolo luso loyikapo la mwana wosabadwayo pakuyika diamondi.
Chifukwa chakukula kwamafuta ndi kuzizira kwapakati, kupsinjika kwakukulu kwamafuta kumapangidwa pamalo olumikizana pakati pa diamondi ndi thupi la tayala, zomwe zimapangitsa kuti diamondi ndi lamba wolumikizana ndi mwana wa fetal apange mizere yaying'ono, motero kuchepetsa kuthekera kwa matayala okutidwa ndi diamondi. Wa diamondi pamwamba ❖ kuyanika akhoza kusintha katundu thupi ndi mankhwala a diamondi ndi mawonekedwe a thupi, mwa kusanthula mphamvu sipekitiramu, anatsimikizira kuti zitsulo carbide zikuchokera mu filimu kuchokera mkati kupita kunja pang'onopang'ono kusintha kwa zinthu zitsulo, wotchedwa MeC-Me filimu, diamondi pamwamba ndi filimu ndi mankhwala chomangira, kokha kuphatikiza izi zikhoza kusintha luso chomangira diamondi, kapena kusintha luso tayala thupi la diamondi. Ndiko kunena kuti, zokutira zimagwira ntchito ngati mlatho womangiriza pakati pa ziwirizi.
2. Sinthani mphamvu ya diamondi.
Chifukwa makhiristo a diamondi nthawi zambiri amakhala ndi zolakwika zamkati, monga ma microcracks, ting'onoting'ono ting'onoting'ono, ndi zina zambiri, zolakwika zamkati mwa makhiristo zimalipidwa podzaza nembanemba ya MeC-Me. Plating imagwira ntchito yolimbitsa ndi kulimbitsa. Chemical plating ndi plating amatha kupititsa patsogolo mphamvu ya zinthu zochepa, zapakati komanso zapamwamba.
3. Chepetsani kutentha kwa kutentha.
Chophimba chachitsulo chimakhala chochedwa kuposa cha diamondi abrasive. Kutentha kogaya kumaperekedwa kwa utomoni womangira wothandizila pakukhudzana ndi tinthu ting'onoting'ono, kotero kuti kawotchedwa kuchokera nthawi yomweyo kutentha kwakukulu, kuti asunge mphamvu yake pa diamondi abrasive.
4. Kudzipatula komanso chitetezo.
Pa kutentha kwambiri sintering ndi akupera kutentha kwambiri, wosanjikiza ❖ kuyanika amalekanitsa ndi kuteteza diamondi kuteteza graphitization, makutidwe ndi okosijeni kapena kusintha zina mankhwala.
