Ngenxa yovavanyo lobunzima beVickers kunye nobunzima be-microhardness, i-engile yedayimani ye-indenter esetyenziselwa ukulinganisa iyafana. Abathengi bafanele bayikhethe njani i-Vickers hardness tester? Namhlanje, ndiza kuchaza ngokufutshane umahluko phakathi kwe-Vickers hardness tester kunye ne-microhardness tester.
Ulwahlulo lobungakanani bamandla ovavanyo Isikali sovavanyo sobunzima beVickers kunye nobunzima be-microhardness
Umvavanyi wobulukhuni beVickers: amandla ovavanyo F≥49.03N okanye≥I-HV5
Ubunzima beVickers yomthwalo omncinci: amandla ovavanyo 1.961N≤F < 49.03N okanye HV0.2 ~ < HV5
Umvavanyi wobunzima beMicro: amandla ovavanyo 0.09807N≤F < 1.96N okanye HV0.01 ~ HV0.2
Ngoko ke sifanele sikhethe njani amandla ovavanyo afanelekileyo?
Sifanele silandele umgaqo wokuba xa ukugoba kukhulu, kokukhona ixabiso lokulinganisa lichaneke ngakumbi ukuba iimeko zomsebenzi ziyavuma, kwaye sikhethe njengoko kufuneka, kuba xa ukugoba kuncinci, kokukhona impazamo enkulu ekulinganiseni ubude obujikelezayo, nto leyo eya kukhokelela ekwandeni kwempazamo yexabiso lobulukhuni.
Amandla ovavanyo lwe-microhardness tester axhotyiswe ngokubanzi ngala: 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) ungayikhetha)
Ukwandiswa ngokubanzi kuxhotyiswe ngezi zinto zilandelayo: amaxesha ali-100 (ukujonga), amaxesha angama-400 (ukulinganisa)
Inqanaba lamandla ovavanyo lovavanyo lobunzima beVickers linokwahlulwahlulwa libe: 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) (iimodeli ezahlukeneyo zineendlela ezahlukeneyo zovavanyo lwamandla.)
Uqwalaselo lokukhulisa ngokubanzi luba: amaxesha ali-100, amaxesha angama-200
Umvavanyi wobulukhuni beVickers weShandong Shancai/Laizhou Laihua Testing Instrument unokwenza uvavanyo lobulukhuni kwiindawo ezidityanisiweyo okanye kwiindawo zokudityanisa.
Ngokwexabiso lobunzima obulinganisiweyo, umgangatho we-weld kunye notshintsho lwe-metallurgical lunokugwetywa. Umzekelo, ubunzima obuphezulu kakhulu bunokubangelwa kukufakwa kobushushu obugqithisileyo ngexesha lokuwelda, ngelixa ubunzima obuphantsi kakhulu bunokubonisa iingxaki zokuwelda ezinganeleyo okanye zomgangatho wezinto.
Inkqubo yokulinganisa iVickers ecwangcisiweyo iya kuqhuba inkqubo yovavanyo oluzenzekelayo ngokupheleleyo kwaye ibonise kwaye irekhode iziphumo ezihambelanayo.
Kwiziphumo zovavanyo lokulinganisa, ingxelo yemizobo ehambelanayo inokwenziwa ngokuzenzekelayo.
Kubalulekile ukuqaphela ukuba xa ukhetha indawo emele.Xa usenza i-weld, qiniseka ukuba le ndawo ayinazo iimbobo, imifantu okanye ezinye iziphene ezinokuchaphazela iziphumo zovavanyo.
Ukuba unemibuzo malunga nokuhlolwa kwe-weld, zive ukhululekile ukuqhagamshelana nathi
