Ibizamini byinshi bisanzwe bya Vickers hard tester

 

1. Koresha uburyo bwo gupima ubukana bwa Vickers mu bice byayo byasutswe (Weld Vickers hardness test):

Kubera ko imiterere y'igice gifatanye cy'ubushuhe (umushono wo gusudira) mu gihe cyo gusudira izahinduka mu gihe cyo gushyiraho, ishobora gukora isano idakomeye mu nyubako ihujwe. Ubukomere bw'ubushuhe bushobora kugaragaza neza niba inzira yo gusudira ikwiye. Hanyuma uburyo bwo kugenzura ubushuhe bwa Vickers ni uburyo bufasha gusuzuma ubwiza bw'ubushuhe. Umushuhe wa Vickers wo mu ruganda rwa Laizhou Laihua Hardness Tester Factory ashobora gukora isuzuma ry'ubushuhe ku bice bihujwe cyangwa ahantu ho gusudira. Mu gihe ukoresha umushuhe wa Vickers mu gupima ibice bihujwe, ibisabwa bikurikira bigomba kwitabwaho:

Uburebure bw'icyitegererezo: Mbere yo gupima, dusya isudi igomba gupimwa kugira ngo ubuso bwayo burusheho kuba bwiza, budafite urwego rwa okiside, imyanya n'ibindi bitagira inenge.

Ku murongo wo hagati w'umushongi, fata akantu gato ku buso bugose buri mm 100 kugira ngo upime.

Guhitamo imbaraga zitandukanye zo gupima bizatanga ibisubizo bitandukanye, bityo tugomba guhitamo imbaraga zikwiye zo gupima mbere yo gupima.

2. Ni gute wakoresha Vickers hardness tester (micro Vickers hardness tester) kugira ngo umenye uburebure bw'urwego rukomeye?

Ni gute wamenya ubujyakuzimu bw'urwego rukomeye rw'ibice by'icyuma hakoreshejwe uburyo bwo kuvugurura ubuso nko gukaraba, gusiga nitride, gukuramo karubone, gukaraba, nibindi, hamwe n'ibice by'icyuma byazimye?

Ubujyakuzimu bw'urwego rukomeye bukoreshwa cyane cyane mu gushyushya ubuso kugira ngo butere impinduka mu miterere n'imikorere ku buso bw'icyuma kugira ngo kigere ku ngaruka zo kongera ubukana n'imbaraga n'ubukomere. Bivuga gupima uhereye ku cyerekezo gihagaze cy'ubuso bw'igice kugeza ku mupaka wa microstructure wagenwe. Cyangwa intera y'urwego rukomeye rw'ubukomere bwa microstructure yagenwe. Ubusanzwe dukoresha uburyo bwa gradient hardness bwa Vickers test hardness kugira ngo tumenye ubujyakuzimu bw'urwego rukomeye rw'igikoresho. Ihame ni ukumenya ubujyakuzimu bw'urwego rukomeye bushingiye ku mpinduka mu bukomere bwa micro-Vickers kuva ku buso kugera hagati mu gice.

Ku bijyanye n'uburyo bwihariye bwo gukora, nyamuneka reba videwo y'imikorere ya Vickers yo mu kigo cyacu. Ibi bikurikira ni intangiriro yoroshye y'imikorere:

Tegura icyitegererezo uko bikenewe, hanyuma ubuso bw'ikizamini bugomba gusigwa bugashyirwa ku buso bw'indorerwamo.

Hitamo imbaraga zo gupima za Vickers hard tester. Uburemere bw'uburemere bupimirwa ahantu habiri cyangwa henshi. Uburemere bwa Vickers bupimirwa ku murongo umwe cyangwa myinshi iteganye igororotse ku buso.

Gukoresha umurongo w'ubukana bushingiye ku makuru yapimwe, bizwi ko intera ihagaze kuva ku buso bw'igice kugeza kuri 550HV (muri rusange) ari bwo bujyakuzimu bw'urwego rukomeye.

3. Ni gute wakoresha icyuma gipima ubukana bwa Vickers mu gupima ubukana bwa mvune (uburyo bwo gupima ubukana bwa Vickers)?

Ubukomere bw'ivunika ni agaciro k'ubudahangarwa bugaragazwa n'ibikoresho iyo ingano cyangwa igice cyabyo cyavunitse mu bihe bidakomeye nk'ivunika cyangwa inenge nk'iz'ivunika.

Ubukomere bw'ivunika bugaragaza ubushobozi bw'ikintu mu gukumira ikwirakwira ry'imyanya kandi ni ikimenyetso cy'ubukomere bw'ikintu.

Mu gihe ukora ikizamini cyo gukomera kw'ivunika, banza utose ubuso bw'ikizamini ku buso bw'indorerwamo. Ku gipimo cyo gukomera kwa Vickers, koresha icyuma gipima diyama gifite ishusho y'icyuma gipima gukomera kwa Vickers kugira ngo ukore agace gato ku buso butoshye bufite umutwaro wa 10Kg. Imyanya yakozwe mbere ikorwa ku mpande enye z'ikimenyetso. Muri rusange dukoresha igipimo cyo gukomera kwa Vickers kugira ngo tubone amakuru y'imbaraga z'ivunika.
