Uvavanyo loBulukhuni beCore yiMicro Vickers Hardness Tester

Kwiinkqubo zokuqinisa umphezulu wesinyithi ezifana nokugalela i-carburizing, i-nitriding kunye nokucima i-induction, ukuvavanywa kobunzima be-core kunye nobunzulu be-maleya eqinileyo, kunye neziphene kwiinkqubo zonyango lobushushu, kuya kuchaphazela iimpawu zoomatshini ngokubanzi zeemveliso. Sisebenzisa i-micro Vickers hardness tester ukugqibezela yonke inkqubo yovavanyo kunye nokulawula ubunzulu be-maleya eqinileyo, isalathisi esiphambili solawulo lomgangatho.

1. Ukulungiselela iSampuli

· Khetha inxalenye yovavanyo okanye isampuli eqhelekileyo uze usike icandelo elinqamlezileyo ukuqinisekisa ukuba umphezulu ovavanyiweyo uthe tyaba, awunazo iinguqu kwaye awunazo iimbumbulu.

· Gaya uze upolisha icandelo elinqamlezileyo ukuze ususe umaleko we-oxide yomphezulu kunye neempawu zomatshini.

· Yikrole njengoko kufuneka ngokwemigangatho efanelekileyo (ukuba kuyimfuneko) ukuze uhlukanise ngokucacileyo umaleko womphezulu kwisakhiwo esiphambili.

2.Uvavanyo loBulukhuni obuPhambili

Sisebenzisa iModel MHV-1000AT micro Vickers hardness tester ukuze sigqibezele yonke inkqubo yovavanyo.

· Beka isampuli ngokukhuselekileyo kwisigaba sovavanyo lobunzima beMicro Vickers uze uyilungelelanise kwindawo engundoqo (kude nomaleko oqinileyo womphezulu).

· Seta amandla ovavanyo (adla ngokuba yi-HV1.0) kunye nexesha lokuhlala, kwaye uqinisekise ukuba izixhobo zilinganiswe ngokufanelekileyo.

· Khetha iindawo zokulinganisa ezifanayo ezi-3 ukuya kwezi-5 embindini, uphephe iziphene ezifana nokuvuleka, imingxunya yomoya kunye nezinto ezifakiweyo.

· Qalisa ukulinganisa; amaxabiso obulukhuni afundwa ngokuzenzekelayo, kwaye ixabiso eliqhelekileyo lithathwa njengesiphumo sokugqibela sobulukhuni obungundoqo.

3. Uvavanyo lobunzulu beLayer eqinisiweyo

· Lungisa iindawo zovavanyo ngokwezikhewu ezilinganayo kumgca othe tye ukusuka kumphezulu ukuya embindini, uze ubeke umgama wenyathelo ngokuhambelana nemigangatho efanelekileyo (edla ngokuba yi-10–50 μm).

· Linganisa inqaku lobunzima ngenqaku, uze ubhale phantsi ixabiso lobunzima kunye nobunzulu obuhambelanayo besikhundla ngasinye.

· Qhubeka nokulinganisa ude ubulukhuni buzinze ngaphantsi kwexabiso elibalulekileyo, uze uyeke uvavanyo.

4. Ukugweba Ubunzulu Bomaleko Obuqinisiweyo (CHD)

· Chonga ixabiso lobunzima obubalulekileyo ngokuhambelana nemigangatho ehambelanayo (umz., GB/T 9450).

· Fumana indawo apho ubulukhuni buqala khona ukuhla bufikelele kwixabiso elibalulekileyo; obu bunzulu buchazwa njengobunzulu obusebenzayo bomaleko oqinileyo.

5. Ukucutshungulwa kweDatha kunye nokuNika ingxelo

· Yila ijika losasazo lobunzima ngobunzulu njenge-axis ethe tye kunye nobunzima njenge-axis ethe nkqo ukuze ubonise i-gradient yobunzima.

· Hlela idatha equka ubulukhuni obuphambili, ubunzulu bomaleko obomeleleyo kunye negophe lobulukhuni ukuze kuveliswe ingxelo yovavanyo.

Uvavanyo lobunzima nobunzulu olungaphezulu lwenziwa yi

Umatshini wokusika i-metallographic we-Q-80Z

Umatshini wokugaya nokupolisha we-metalogtaphic ozenzekelayo we-MP-2000

Isivavanyeli sobunzima be-MHV-1000AT micro Vickers
