Ukusetyenziswa komvavanyi wobulukhuni

Umvavanyi wobulukhuni sisixhobo sokulinganisa ubulukhuni bemathiriyeli. Ngokwezixhobo ezahlukeneyo ezilinganiswayo, umvavanyi wobulukhuni unokusetyenziswa kwiindawo ezahlukeneyo. Abanye abavavanyi bobulukhuni basetyenziswa kwishishini lokulungisa oomatshini, kwaye ubukhulu becala balinganisa ubulukhuni bemathiriyeli yentsimbi. Ezinje: Brinell umvavanyi ubulukhuni, Rockwell ubulukhuni umvavanyi, Leeb ubulukhuni tester, Vickers umvavanyi ubulukhuni, microhardness umvavanyi, Shore ubulukhuni umvavanyi, Webster ubulukhuni umvavanyi njl. Imida yesicelo ethile yaba bavavanyi ubulukhuni ngolu hlobo lulandelayo:

Brinell ubulukhuni tester:ikakhulu isetyenziselwa uvavanyo lobulukhuni bentsimbi ekhandiweyo kunye nentsimbi ekhatywayo enesakhiwo esingalinganiyo. Ukuqina kweBrinell yentsimbi ekhandiweyo kunye nentsimbi engwevu inembalelwano elungileyo kunye novavanyo lokuqina. Uvavanyo lobulukhuni be-Brinell lunokusetyenziselwa iintsimbi ezingenayo i-ferrous kunye nentsimbi ethambileyo. I-indenter yebhola encinci inokulinganisa ubungakanani obuncinci kunye nezixhobo ezibhityileyo, kwaye ilinganise iindawo zokulungisa ubushushu kunye namasebe okuhlola umzi-mveliso weefektri ezahlukeneyo zoomatshini. I-Brinell tester hardness isetyenziswa kakhulu ekuhloleni imathiriyeli ekrwada kunye neemveliso ezigqityiweyo. Ngenxa yokungeniswa okukhulu, ngokuqhelekileyo ayisetyenziselwa ukuhlolwa kwemveliso egqityiweyo.

 

Rockwell ubulukhuni umvavanyi:Vavanya iintlobo ngeentlobo zesinyithi kunye nesinyithi, vavanya ubulukhuni bentsimbi ecinyiweyo, intsimbi ecinyiweyo kunye nobushushu, intsimbi ene-annealed, i-case-hardened steel, iipleyiti ezinobunzima obahlukeneyo, izinto ze-carbide, izixhobo zetsimbi yomgubo, iingubo zokutshiza ezishushu, ii-castings ezipholileyo, ii-alloys ze-aluminium, iipleyiti zentsimbi, ukuqina, njl.

I-Superficial Rockwell Hardness Tester:Isetyenziselwa ukuvavanya ubulukhuni becwecwe lesinyithi, umbhobho wodonga obhityileyo, intsimbi eqinile kunye namalungu amancinci, i-alloy eqinile, i-carbide, i-case hardened, i-case hardened, i-sheet hardened, i-hardened sheet, isinyithi esicinyiweyo kunye nobushushu, intsimbi epholileyo, intsimbi, i-aluminium, ubhedu, i-magnesium kunye nezinye iintsimbi ze-alloy.

 

Umvavanyi wobulukhuni beVickers: ukulinganisa iindawo ezincinci, iipleyiti zetsimbi ezibhityileyo, iifoyile zetsimbi, iishiti ze-IC, iingcingo, iileya eziqinileyo, iileya ze-electroplated, iglasi, ubucwebe kunye neeseramics, isinyithi esinesinyithi, isinyithi esingeyontsimbi, iishiti ze-IC, iingubo zomphezulu, iintsimbi ezilaminethiweyo; iglasi, iiseramics, iagate, amatye anqabileyo, njl.; ubunzulu kunye novavanyo lobulukhuni begradient yeeleya zekhabhoni kunye nokucima iileya ezilukhuni. Ukusetyenzwa kwehardware, ishishini lombane, izincedisi zokungunda, ishishini lokubukela.

 

Knoopumvavanyi wobulukhuni:esetyenziswa ngokubanzi ukulinganisa ubulukhuni besampulu ezincinci kunye nezibhityileyo, iingubo zokungena kumphezulu kunye neminye imizekelo, kunye nokulinganisa ubulukhuni be-Knoop yezinto ezinqabileyo kunye nezilukhuni ezifana neglasi, i-ceramics, i-agate, amatye anqabileyo okufakelwa, njl.

 

Leeb umvavanyi wobulukhuni:intsimbi kunye nentsimbi, intsimbi yentsimbi, intsimbi engwevu, intsimbi yentsimbi, intsimbi ye-aluminiyam, ingxubevange yobhedu-zinc (ubhedu), i-copper-tin ialloy (ubhedu), ubhedu olusulungekileyo, isinyithi esibunjiweyo, intsimbi ye-carbon, intsimbi ye-chrome, i-chrome-vanadium steel, i-chrome-nickel steel, i-chrome-molybdenum, i-silicone-high-iron, intsimbi, i-silicone, isinyithi, njl.

 

Shintsimbiumvavanyi wobulukhuni:Ikakhulu isetyenziselwa ukulinganisa ubulukhuni beeplastiki ezithambileyo kunye nerabha yobulukhuni eqhelekileyo, njengerabha ethambileyo, irabha yokwenziwa, iirola zerabha yoshicilelo, i-thermoplastic elastomers, ufele, njl njl. Isetyenziswa ngokubanzi kushishino lweplastiki, ishishini lerabha kunye namanye amashishini ekhemikhali, kubandakanywa ubulukhuni beplastiki eqinile kunye nerabha enzima, njengezinto ezinqabileyo, ezifana ne-bowls, njl njl. ifanelekile kwisiza sokulinganisa ubulukhuni berabha kunye neemveliso zeplastiki ezigqityiweyo.
