Ibizamini byinshi bisanzwe bya Vickers gukomera

 

1. Koresha igeragezwa rya Vickers ibice byo gusudira (Ikizamini cya Weld Vickers):

Kubera ko microstructure yibice bihuriweho byo gusudira (weld seam) mugihe cyo gusudira bizahinduka mugihe cyo gushinga, birashobora gukora ihuriro ridakomeye muburyo bwo gusudira.Ubukomezi bwo gusudira burashobora kwerekana mu buryo butaziguye niba uburyo bwo gusudira bufite ishingiro.Noneho gukomera kwa Vickers Uburyo bwo kugenzura nuburyo bufasha gusuzuma ubwiza bwa weld.Igeragezwa rya Vickers ryuruganda rwa Laizhou Laihua Uruganda rukora ibizamini rushobora gukora ibizamini byo gukomera kubice byasuditswe cyangwa ahantu ho gusudira.Mugihe ukoresheje ibizamini bya Vickers kugirango ugerageze ibice byasudiwe, hagomba kwitonderwa ibi bikurikira:

Uburinganire bw'icyitegererezo: Mbere yo kwipimisha, turasya gusudira kugirango tugerageze kugirango ubuso bwabwo bugende neza, butarimo okiside ya oxyde, ibice nibindi bitenge.

Ku murongo wo hagati wa weld, fata ingingo hejuru yuhetamye buri mm 100 kugirango ugerageze.

Guhitamo imbaraga zitandukanye zo kugerageza bizavamo ibisubizo bitandukanye, tugomba rero guhitamo imbaraga zikwiye mbere yo kwipimisha.

2. Nigute ushobora gukoresha igeragezwa rya Vickers (micro Vickers hardness tester) kugirango umenye ubujyakuzimu?

Nigute ushobora kumenya ubujyakuzimu bw'igice gikomye cy'ibyuma hamwe no kuvura hejuru nka karburizasi, nitride, decarburisation, karubone, n'ibindi, hamwe n'ibice by'ibyuma byazimye?

Ubujyakuzimu bukomeye bwakoreshejwe cyane cyane gushyushya ubuso kugirango butere imiterere n'imikorere hejuru yicyuma kugirango bigere ku ngaruka zo kongera ubukana n'imbaraga no gukomera.Yerekeza ku gupima kuva ku cyerekezo gihagaritse cy'igice cy'ubutaka kugera ku mbibi za microstructure.Cyangwa intera ikomye intera ya microhardness yagenwe.Mubisanzwe dukoresha buhoro buhoro uburyo bukomeye bwo gupima Vickers kugirango tumenye neza uburemere bwimbitse bwakazi.Ihame ni ukumenya ubujyakuzimu bukomeye bushingiye ku ihinduka rya micro-Vickers gukomera kuva hejuru kugeza hagati hagati.

Kuburyo bwihariye bwo gukora, nyamuneka reba amashusho yimikorere ya sosiyete yacu ya Vickers.Ibikurikira nuburyo bworoshye bwo gutangiza:

Tegura icyitegererezo nkuko bisabwa, kandi igeragezwa rigomba guhanagurwa hejuru yindorerwamo.

Hitamo imbaraga zipimisha za Vickers zipima.Ubukomezi buringaniye bupimirwa ahantu habiri cyangwa byinshi.Ubukomezi bwa Vickers bupimirwa kumurongo umwe cyangwa myinshi iringaniye itandukanijwe hejuru.

Gushushanya umurongo ukomeye ushingiye kumibare yapimwe, birashobora kumenyekana ko intera ihagaritse kuva hejuru yikigice kugeza kuri 550HV (muri rusange) nuburyo bwimbitse bukomeye.

3. Nigute ushobora gukoresha ibizamini bya Vickers mugupima gukomera (kuvunika gukomera Vickers uburyo bwo gupima ubukana)?

Gukomera kuvunika nigiciro cyo kurwanya cyerekanwa nibikoresho mugihe ingero cyangwa ibice byavunitse mubihe bidahungabana nkibice cyangwa inenge zimeze.

Gukomera kuvunika byerekana ubushobozi bwibintu kugirango wirinde gukwirakwira kandi ni igipimo cyerekana ubukana bwibintu.

Mugihe ukora ikizamini cyo kuvunika gukomera, banza usige hejuru yikigereranyo cyikigereranyo hejuru yindorerwamo.Kwipimisha ubukana bwa Vickers, koresha indangururamajwi ya diyama ya test ya Vickers igerageza gukora indentation hejuru yubururu hamwe nuburemere bwa 10Kg.Ibice byateguwe byakozwe kuri vertike enye yikimenyetso.Mubisanzwe dukoresha ibizamini bya Vickers kugirango tubone amakuru yo gukomera.
