Lub Universal hardness tester yog qhov tseeb yog ib qho cuab yeej ntsuas kev ua tiav raws li ISO thiab ASTM cov qauv, tso cai rau cov neeg siv ua qhov kev ntsuas Rockwell, Vickers thiab Brinell hardness ntawm tib lub cuab yeej. Lub Universal hardness tester raug kuaj raws li Rockwell, Brinell, thiab Vickers cov ntsiab cai es tsis yog siv kev hloov pauv ntawm qhov system hardness los txiav txim siab ntau yam nqi hardness.
Lub HB Brinell hardness scale yog tsim rau kev ntsuas qhov nyuaj ntawm cov hlau cam khwb cia, cov hlau tsis yog ferrous, thiab ntau yam hlau annealed thiab tempered. Nws tsis haum rau kev ntsuas cov qauv lossis cov khoom ua haujlwm uas nyuaj dhau, me dhau, nyias dhau, thiab tsis pub muaj qhov loj ntawm qhov chaw.
HR Rockwell hardness scale yog tsim rau: kev sim pwm, kev ntsuas qhov nyuaj ntawm cov khoom quenched, quenched thiab tempered cua sov kho.
HV Vickers hardness scale yog tsim rau: ntsuas qhov nyuaj ntawm cov qauv thiab cov khoom nrog thaj chaw me me thiab cov nqi hardness siab, qhov nyuaj ntawm cov txheej infiltrated lossis coatings tom qab ntau yam kev kho deg, thiab qhov nyuaj ntawm cov ntaub ntawv nyias.
Cov hauv qab no yog kev qhia txog cov koob tshiab ntawm Universal hardness testers: thiab lub vijtsam kov Universal Hardness Tester
Txawv ntawm cov cuab yeej ntsuas qhov nyuaj Universal ib txwm muaj, cov cuab yeej ntsuas qhov nyuaj Universal tiam tshiab siv cov thev naus laus zis sensor thiab lub kaw lus teb rov qab los hloov cov qauv hnyav, ua rau kev ntsuas yooj yim dua thiab tus nqi ntsuas ruaj khov dua.
