Ngenxa yokuhlolwa kobulukhuni be-Vickers kanye nobunzima be-microhardness, i-engeli yedayimane ye-indenter esetshenziswa ekulinganisweni iyafana. Amakhasimende kufanele ayikhethe kanjani i-Vickers hardness tester? Namuhla, ngizochaza kafushane umehluko phakathi kwe-Vickers hardness tester kanye ne-microhardness tester.
Isikali sokuhlola ubulukhuni kanye nobunzima be-microhardness Vickers
Isihloli sobulukhuni beVickers: amandla okuhlola F≥49.03N noma≥I-HV5
Ubulukhuni be-Vickers yomthwalo omncane: amandla okuhlola 1.961N≤F < 49.03N noma HV0.2 ~ < HV5
Umhloli wokuqina kwe-Micro: amandla okuhlola 0.09807N≤F < 1.96N noma HV0.01 ~ HV0.2
Ngakho-ke kufanele sikhethe kanjani amandla okuhlola afanele?
Kufanele silandele isimiso sokuthi uma ukugoba kukhulu, kulapho inani lokulinganisa liba linembile khona uma izimo zomsebenzi zivumela, futhi sikhethe njengoba kudingeka, ngoba uma ukugoba kuncane, kulapho iphutha elikhulu ekulinganiseni ubude obuqondile, okuzoholela ekwandeni kwephutha lenani lobulukhuni.
Amandla okuhlola esihloli sokuqina kwe-micro ngokuvamile ahlonyiswe nge: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N (500gf), 9.80N (1000gf) (19.6N (2.0Kgf) ongazikhethela)
Ukukhulisa ngokuvamile kuhlonyiswe nge: izikhathi eziyi-100 (ukubuka), izikhathi ezingama-400 (ukulinganisa)
Izinga lamandla okuhlola le-Vickers hardness tester lingahlukaniswa kanje: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 98.0N (10Kgf), 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (amamodeli ahlukene anezilungiselelo ezahlukene zamandla okuhlola.)
Ukucushwa kokukhulisa ngokuvamile: izikhathi eziyi-100, izikhathi ezingama-200
Umhloli wobulukhuni be-Vickers we-Shandong Shancai/Laizhou Laihua Testing Instrument angenza ukuhlolwa kobulukhuni ezingxenyeni ezihlanganisiwe noma ezindaweni zokushisela.
Ngokwenani lobunzima elilinganisiwe, ikhwalithi yezinguquko ze-weld kanye neze-metallurgical ingahlulelwa. Isibonelo, ubunzima obukhulu kakhulu bungaba ngenxa yokufaka ukushisa ngokweqile ngesikhathi sokushisela, kanti ubunzima obuphansi kakhulu bungase bubonise izinkinga zokushisela ezinganele noma zekhwalithi yezinto ezibonakalayo.
Uhlelo lokulinganisa lwe-Vickers oluhleliwe luzosebenzisa uhlelo lokuhlola oluzenzakalelayo ngokuphelele futhi lubonise futhi lurekhode imiphumela ehambisanayo.
Ngemiphumela yokuhlolwa kokulinganisa, umbiko wesithombe ohambisanayo ungakhiqizwa ngokuzenzakalelayo.
Kubalulekile ukuqaphela ukuthi lapho ukhetha indawo emele.Uma ufaka i-weld endaweni yokuhlola, qiniseka ukuthi le ndawo ayinazo izimbobo, imifantu noma ezinye iziphambeko ezingathinta imiphumela yokuhlolwa.
Uma unemibuzo mayelana nokuhlolwa kwe-weld, zizwe ukhululekile ukuxhumana nathi
