Gukomera aho urusya rushobora gufasha gusuzuma ubushishozi bwa Weld, bityo bikagufasha kumenya ubushobozi bukenewe, bityo urubwizego gisaba gupima ubukana nuburyo bufasha gusuzuma ubwiza bwa Weld.
Shandong Shancai / Laizhou Laihhou Ikizamini cyo gupima Isosiyete ikora nabi testers irashobora gukora gupima gukomera ku bice bisuye cyangwa gusudira. Iyo ugerageza gukomera kwibintu bisundutse, ibipimo byinshi bizakorwa kumwanya runaka uhereye kumpera yicyitegererezo cyangwa hejuru yicyo gihe cyo gusudira. Nyuma yo kubona indentation amanota menshi, agaciro gakomeye karashobora gupimwa no gupima gukomeza kandi igishushanyo cyumurongo gishobora kuboneka.
Mugihe ukoresheje vickers gukomera kugirango ugerageze ibice asuye, ibizamini bikurikira bigomba kwitonderwa:
1. Gufunga icyitegererezo: Mbere yo kwipimisha, dusya urusaku kugirango tugeragezwe kugirango ubuso bwayo bworoshye, butarimo okiside nindi mbururu.
2. Ku murongo wagati wa Weld, fata ingingo ku buso bugoramye buri mm 100 yo kwipimisha.
3. Guhitamo ingabo zitandukanye bizavamo ibisubizo bitandukanye, bityo tugomba guhitamo imbaraga zikwiye mbere yo kwipimisha.
Icyapa cya microhardness gifite ibisabwa kugirango usohore hejuru yicyitegererezo, kigomba gutegurwa neza ukurikije icyitegererezo.
Ihame rya Microhardss muri microhardness uburyo bumeze neza nka vickers ubukana, ariko umutwaro ukoreshwa ni muto, nicy'ibizamini bya Microhards ni bike bitanga uburyo bworoshye bwo gukora ibintu bisanzwe. Byakoreshejwe cyane kugirango tumenye ubukana bwa buri cyiciro hejuru no mu gice cyo gushimangira.
Ikimenyetso cya microhardness gisanzwe kigaragazwa na HV, no kugena ihame nuburyo busa na vickers. Sisitemu yo gupakira, Gupima Sisitemu no Gusimburana neza muri testerness ya microhardness biranshimishije kuruta ibyo umutwaro uke cyane wo gukomera. Kuri ubu, testerness testers ikoreshwa cyane mubikorwa bito, kandi kuberako ubukuru bushobora kugera kuri 400, akenshi bikoreshwa nka microscope yoroshye.
Muburyo bwo gukoresha, kwitabwaho bigomba kwishyurwa kumutwaro, micrometero hamwe na linter testerness testerness, bigomba kugenzurwa mbere yo gukoresha, kandi gukomera bikoreshwa mugukoresha neza agaciro kayo kerekana agaciro kayo kerekana agaciro kayo.
Icyapa cya Microhardss gikoreshwa umutwaro mubikorwa byikizamini muburyo bworoshye kandi bushoboka, nta ngaruka. Kugirango tumenye ibisubizo byikizamini, mubisanzwe birakenewe gupima inshuro nyinshi mubice bitandukanye, hanyuma ushake impuzandengo yagaciro kugirango uhagararire agaciro gakomeye k'ibizamini byikizamini cyangwa alloy icyiciro. Kuburyo bwo kumenagura ku bushyuhe bwinshi, ubukana bwayo burashobora gupimwa no gukoresha tester yubushyuhe bwinshi.
