Apha ngezantsi kukho iisampulu zeseramikhi ezijikelezileyo ezithunyelwa ngumthengi ukuze kuvavanywe ubulukhuni. Ukuze silinganise ngokuchanekileyo ubulukhuni bomphezulu wezinto zebhola yeseramikhi kwaye siqinisekise iziphumo zovavanyo ezichanekileyo nezithembekileyo, senza uvavanyo lobulukhuni kwiisampulu zebhola yeseramikhi sisebenzisa isixhobo sokuvavanya ubulukhuni semicro Vickers.

Ekubeni iisampuli zebhola zeseramikhi zingqukuva kwaye zincinci ngobukhulu, nto leyo eyenza kube nzima ukuzibamba, kufuneka kuqalwe ngokufakelwa kwe-metallographic kunye nokupolisha ngaphambi kokulinganisa ubunzima ngokuhambelana neenkqubo ezisemgangathweni.

Inkqubo yokuFakela iisampuli:

Iisampuli zebhola zeseramikhi zincinci ngobukhulu kwaye azinakubotshwa okanye zilungiswe, nto leyo eyenza kube nzima ukuzibeka kwindawo yazo ngexesha lovavanyo. Sisebenzisa i-ZXQ‑2S metallographic mounting press engezantsi ukulungiselela iisampuli zeseramikhi zibe ziisampuli zovavanyo:

Beka isampuli kwimold ye-metallographic mounting press, kwaye wenze i-installing kunye ne-fixing ngokusebenzisa i-hot installing. Le nkqubo yenza ibhola ye-ceramic ibe yibhloko yesampuli eqhelekileyo enemilo eqhelekileyo kunye nomphezulu wovavanyo oluthe tyaba, ukuqinisekisa ukuba umphezulu othe tyaba ozinzileyo wokuvavanya nokulungisa ubulukhuni emva koko.

Ukusila nokupolisha iisampuli:

Emva kokuba kugqityiwe ukufakwa, umphezulu webhloko efakelweyo uqala ngokugaya okurhabaxa, ukugaywa nokupholishwa kusetyenziswa umatshini wokugaya nokupholishwa nge-metallographic. Umphezulu wovavanyo emva koko upholishwa kakuhle ngelaphu levelvet ude umphezulu ube mpuluswa, ungabi nazikrwelo kunye neengqimba zokuguqulwa, ukuhlangabezana neemfuno zokugqitywa kwesibuko zovavanyo lobunzima be-micro Vickers.

Ukuqiniswa kunye nokuQokelelwa kweMifanekiso:

Beka isampuli ekhazimlisiweyo ngokuthe chu kwinqanaba le-HVT-1000A micro Vickers hardness tester, yenza uvavanyo lweVickers ngokuhambelana neenkqubo zokusebenza ze-Vickers hardness tester, kwaye ufumane ixabiso lobunzima (jonga la manyathelo alandelayo ukuze ufumane iinkcukacha ezithe vetshe).

Useto lweParamitha yoVavanyo:

Ngokwezinto zebhola zeseramikhi kunye neemfuno ezisemgangathweni, khetha isikali sovavanyo esifanelekileyo kunye namandla ovavanyo lwe-HVT-1000A micro Vickers hardness tester. Seta iiparameter ezifana nexesha lokuhlala, inani lamanqaku ovavanyo, kunye nemo yokulinganisa kwisoftware yezixhobo. Emva kokuqinisekisa ukuba iiparameter zichanekile, faka imeko yovavanyo.

Ukulayisha kunye nokulinganisa i-Indentiation:

Emva kokuba uvavanyo luqalisiwe, i-HVT-1000A micro Vickers hardness tester iza kwenza ngokuzenzekelayo i-loading-dwell-unloading. Ngexesha lokulinganisa i-indentation, inkqubo ichonga ngokuzenzekelayo umda we-indentation. Ngokuqalisa ukulinganisa ngokuzenzekelayo okanye ngesandla, inkqubo yokulinganisa ifumana ngokuthe ngqo ixabiso le-hardness. Okwangoku, idatha efana nobude be-diagonal iboniswa ngexesha langempela kwaye ingarekhodwa kwaye igcinwe.

Isalathiso seMveliso:

Uvavanyo olungentla lwenziwa yi-ZXQ-2S metallographic mounting press kunye ne-HVT-1000A micro Vickers hardness tester yenkampani yethu. Ukuba unomdla koku, nceda ujonge iwebhusayithi engezantsi, enkosi!
