Ngenxa yobulukhuni beVickers kunye novavanyo lwe-microhardness, i-angle yedayimane ye-indenter esetyenziselwa ukulinganisa iyafana. Ngaba abathengi kufuneka bakhethe njani umvavanyi wobulukhuni beVickers? Namhlanje, ndiza kuchaza ngokufutshane umahluko phakathi kwe-Vickers hardness tester kunye ne-microhardness tester.
Uvavanyo lwamandla obungakanani becandelo leVickers ubulukhuni kunye ne-microhardness tester scale
Vickers umvavanyi wobulukhuni: amandla ovavanyo F≥49.03N okanye≥HV5
Umthwalo omncinci ubunzima beVickers: amandla okuvavanya i-1.961N≤F < 49.03N okanye HV0.2 ~ < HV5
Umvavanyi we-Microhardness: amandla ovavanyo 0.09807N≤F < 1.96N okanye HV0.01 ~ HV0.2
Ke kufuneka sikhethe njani amandla ovavanyo afanelekileyo?
Sifanele silandele umgaqo wokuba i-indentation inkulu, ixabiso elichanekileyo lokulinganisa ukuba iimeko ze-workpiece zivumela, kwaye ukhethe njengoko kuyimfuneko, kuba i-indentation encinci, inkulu impazamo ekulinganiseni ubude be-diagonal, okuya kukhokelela ekwandeni kwempazamo yexabiso lobunzima.
Amandla ovavanyo lwe-microhardness tester ngokubanzi ixhotyiswe: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.9gN0), 4.9gN0 (1000gf) (19.6N (2.0Kgf) uyazikhethela)
Ukwandiswa ngokubanzi kuxhotyiswe: amaxesha angama-100 (uqwalaselo), amaxesha angama-400 (umlinganiselo)
Inqanaba lamandla ovavanyo lwe-Vickers tester hardness lingahlulwa libe: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kg0), (5.0Kg0), (5.0Kg0). 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (imifuziselo eyahlukeneyo inolungelelwaniso lwamandla ovavanyo olwahlukileyo.)
Ubumbeko lokukhulisa ngokuqhelekileyo: amaxesha angama-100, amaxesha angama-200
I-Vickers tester hardness ye-Shandong Shancai / i-Laizhou Laihua Testing Instrument inokwenza iimvavanyo zobunzima kwiindawo ezidibeneyo okanye iindawo ze-welding.
Ngokwexabiso lobunzima obulinganisiweyo, umgangatho we-weld kunye neenguqu ze-metallurgical zinokugwetywa. Ngokomzekelo, ubunzima obuphezulu bunokuthi bube ngenxa yegalelo lobushushu obugqithisileyo ngexesha le-welding, ngelixa ubunzima obuphantsi kakhulu bunokubonisa ukungonelanga kwe-welding okanye iingxaki zekhwalithi yezinto.
Inkqubo yokulinganisa i-Vickers emiselweyo iya kuqhuba inkqubo yokuvavanya ngokuzenzekelayo kwaye ibonise kwaye irekhode iziphumo ezihambelanayo.
Kwiziphumo zovavanyo lokulinganisa, ingxelo yegraphic ehambelanayo inokuveliswa ngokuzenzekelayo.
Kubalulekile ukuqaphela ukuba xa ukhetha indawo yommeli we.i-weld njengendawo yokuvavanya, qiniseka ukuba le ndawo ayinayo i-pores, iintanda okanye ezinye iziphene ezinokuchaphazela iziphumo zovavanyo.
Ukuba unayo nayiphi na imibuzo malunga nokuhlolwa kwe-weld, zive ukhululekile ukuqhagamshelana nathi
