Lub tshuab ntsuas nyuaj rau lub hardment yog qhov tseeb ntsuas qhov ntsuas ntawm ISO thiab ASTM cov qauv, tso cai rau cov neeg siv pob zeb, cov tshuaj yaig thiab brinell hardness kev ntsuam xyuas ntawm tib lub twj paj nruag. Lub tsev pheeb suab pob thoob ntiaj teb yog kuaj raws li Rockwell, brinell, thiab vickers cov ntsiab cai es tsis siv txoj kev sib raug zoo ntawm lub zog kev sib raug zoo kom tau txais ntau txoj kev tawv.
HB Brinell hardness nplai yog qhov tsim nyog rau ntsuas lub hardness ntawm cam khwb cia hlau, cov khoom siv tsis sib xws thiab ntau yam. Nws tsis haum rau ntsuas cov qauv lossis cov ua haujlwm uas nyuaj heev, me me, thiab tsis txhob cia cov kev tsis txaus siab loj rau saum npoo.
HR Rockwell Hardness nplai yog qhov tsim nyog rau: Kev sim pwm, nyuaj ntsuas ntawm quenched, quenched thiab tempered tshav kub kho qhov chaw.
HV vickers hardness nplai yog qhov haum rau: ntsuas qhov nyuaj ntawm cov qauv thiab cov tawv nqaij tawv me me, cov txheej txheem ua haujlwm siab tom qab ntau yam khoom siv.
Cov hauv qab no yog kev qhia txog cov tshiab series ntawm universal hardness testers: thiab lub kov screen Universness Towerer
Txawv los ntawm cov tso cai universal hardness tester, lub cim tshiab University ua haujlwm siv cov qauv ntsuas hluav taws xob, ua kom ntsuas qhov yooj yim dua.
