Gukomera kumwanya uri hafi yo gusudira birashobora kugufasha gusuzuma ubunebwe bwa weld, bityo bikagufasha kumenya niba gusudira bifite imbaraga zisabwa, bityo rero uburyo bwo gupima ubudodo bwa Vickers nuburyo bufasha gusuzuma ubuziranenge bwa weld.
Shandong Shancai / Laizhou Laihua Ikizamini Cyibikoresho bya Sosiyete ya Vickers igerageza irashobora gukora ibizamini byo gukomera kubice byasuditswe cyangwa ahantu ho gusudira.Mugihe cyo kugerageza ubukana bwikibanza cyo gusudira, gupima ingingo nyinshi bizakorwa intera runaka uhereye kumpera yicyitegererezo cyangwa hejuru yikibanza cyo gusudira.Nyuma yo kubona ingingo-nyinshi zerekana, agaciro gakomeye gashobora gupimwa no gukomeza guhoraho kandi igishushanyo mbonera gishobora kuboneka.
Mugihe ukoresheje ibizamini bya Vickers kugirango ugerageze ibice byasudutse, hagomba kwitonderwa ibihe bikurikira:
1. Uburinganire bw'icyitegererezo: Mbere yo kwipimisha, turasya gusudira kugirango tugerageze kugirango ubuso bwabwo bugende neza, butarimo okiside ya okiside, ibice ndetse nizindi nenge.
2. Ku murongo wo hagati wa weld, fata ingingo hejuru yuhetamye buri mm 100 kugirango ugerageze.
3. Guhitamo imbaraga zinyuranye zizavamo ibisubizo bitandukanye, tugomba rero guhitamo imbaraga zikwiye mbere yo kwipimisha.
Ikizamini cya microhardness gifite ibisabwa kugirango kirangire hejuru yicyitegererezo cyapimwe, gikeneye gutegurwa neza ukurikije icyitegererezo cya metallografiya.
Ihame ryikizamini cya microhardness muburyo bwo gupima microhardness burasa neza nubukomere bwa Vickers, ariko umutwaro wakoreshejwe ni muto ugereranije nuburemere buke bwa Vickers, ubusanzwe butarenza 1000g, kandi indentation yavuyemo ni microne nkeya kugeza kuri ebyiri microns, bityo ikizamini cya microhardness gitanga uburyo bworoshye bwo kwiga imiterere ya microstructure yimiterere ya layer yemewe.Irakoreshwa cyane kugirango hamenyekane ubukana bwa buri cyiciro hejuru no murwego rwinjira.
Ikimenyetso cya microhardness gikunze kugaragazwa na HV, kandi ihame ryayo nuburyo bwo kugena bisa nuburyo bukomeye bwa Vickers.Sisitemu yo gupakira, gupima sisitemu hamwe no kwerekana neza ibipimo bya microhardness bipimisha birasabwa cyane kuruta ibya Vickers ifite uburemere buke.Kugeza ubu, ibizamini bya microhardness bikoreshwa cyane mubikorwa bito, kandi kubera ko gukura bishobora kugera inshuro 400, akenshi bikoreshwa nka microscope yoroshye.
Muburyo bwo gukoresha, hagomba kwitonderwa umutwaro, micrometero na indenter ya test ya microhardness, bigomba kugenzurwa mbere yo kubikoresha, kandi guhagarika gukomera bikoreshwa mukumenya byimazeyo agaciro kerekana.
Ikizamini cya microhardness ikoresha umutwaro mugikorwa cyikizamini cyoroshye kandi kimwe gishoboka, nta ngaruka no kunyeganyega.Kugirango tumenye neza ibisubizo by'ibizamini, mubisanzwe birakenewe gupima inshuro nyinshi mubice bitandukanye, hanyuma ugashaka agaciro kagereranijwe kugirango ugereranye agaciro gakomeye k'ikizamini cyikizamini cyangwa icyiciro cya alloy.Kubice byinjira byinjira mubushyuhe bwo hejuru, ubukana bwabyo burashobora gupimwa ukoresheje ibipimo byo hejuru bya microhardness.
