Miedzo yakati wandei yeVickers kuomesa kweTester

 

1. Shandisa Vickers Hardness Tester yeTested zvikamu (weld vickers kuomesa bvunzo) nzira:

Sezvo microdructure yeiyo yakabatanidzwa chikamu cheWalmy (weld seam) panguva yekufambisa ichachinja panguva yekuumbwa, inogona kuumba isina kusimba yekubatanidza muchimiro chakarukwa. Kuomarara kweiyo nongororo kunogona kuratidza zvakananga kuti iyo nzira yehutachiona ine musoro. Ipapo vickers kuomesa kuomesa nzira yekuongorora inzira inobatsira kuongorora mhando yeWels. Vickers kuomesa testers yeLaizhou Laihua Hardness Tester fekitori inogona kuita hutsinye kuomesa zvikamu zveWeld. Paunenge uchishandisa Vickers Hardness Tester kuti muedze Zvikamu zveTested, Mamiriro ezvinhu anotevera ekuedzwa anofanira kucherechedzwa:

Kubata sampuli: usati waedza, isu tinokuya weld kuedzwa kuti aone kuti nzvimbo yayo itsike, mahara exide layer, marara uye zvimwe zvikanganiso.

Pamutsetse wepakati weWeld, tora poindi pane yakakomberedzwa pamusoro pegumi nemaviri mm yekuedzwa.

Kusarudza masimba akasiyana emiedzo kuchaguma nemhedzisiro dzakasiyana, saka isu tinofanirwa kusarudza yakakodzera tsika yakakodzera bvunzo usati waedza.

Maitiro ekuona kudzika kweiyo yakaomeswa chikamu chesimbi nezvakarukwa zvakadai sekurapa kwemusoro sekurapa, nitrizing, decarbarization, etc., uye zvikamu zvesimbi zvakadzurwa?

Iyo inoshanda yakaomeswa layer inowanzo shandiswa kune zvemumunda kupisa pamusoro pekukonzera kuomarara uye kuita shanduko pamusoro peiyo simbi kuti uwane mhedzisiro yekuwedzera kuomesera uye kusimba uye kuoma. Izvo zvinoreva kuyerwa kubva kune yakatwasuka kutungamira kwechikamu chekamuri kune yakatarwa micrantture muganho. Kana iyo yakaoma danho rekureba kweiyo microharnness yakatarwa. Kazhinji isu tinoshandisa nzira yekushambadzira yakaoma yeVickers Hardness Tester kuti ione iyo inoshanda yakaomesesa chikamu chebasa rekushanda. Iyo nheyo ndeyekuona iyo inoshanda yakaomeswa layer yakadzika kubva pakuchinja mune micro-vickers kuomarara kubva pakati pechikamu chechikamu.

Zvekutanga nzira dzekushanda, ndapota tarisa kune vedu vekambani vickers kuomesa kweTester Operation vhidhiyo. Izvi zvinotevera chiitiko chiri nyore kushanda:

Gadzirira iyo sampu sezvinodiwa, uye iyo yekuyedza inofanirwa kupukutwa kune girazi pamusoro.

Sarudza simba rekuyedzwa kweVickers hardness tester. Iyo hardness gradient inoyerwa kunzvimbo mbiri kana kupfuura. Iyo Vickers kuomarara kunoyerwa pane imwe chete kana kupfuura yakaenzana mitsara perpendicular kune pamusoro.

Kudhirowa kuomarara kwakavakirwa pane yakayerwa data, inogona kuzivikanwa kuti nzvimbo yakatwasuka kubva pamusoro pechikamu kusvika ku550hv (kazhinji) ndiyo yakasvibirira yakashanda yakadzika.

Kuwedzeredza kukosheswa ndiko kudzivisa kukosha kwakaratidzwa nezvinhu kana iyo fungidziro kana chikamu chinokatyamadza mumamiriro asina kugadzikana akadai semazaya kana kupenga-kunge urema.

Kupwanya kwekunhuwirira kunomiririra kugona kwezvinhu zvekudzivirira kuparadzaniswa kwekuparadzira uye chiratidzo cheyakawandisa chekuomesesa kwechinhu.

Paunenge uchiita bracture kuomarara kwebvunzo, kutanga kupukuta pasi kweyekuyevedza muenzaniso kune girazi pasi. Pane vickers hardness tester Mapundu ezvekutanga anogadzirwa pamidziyo mina yemucherechedzo. Isu tinowanzo shandisa vickers hardness tester kuti uwane kupwanya data roughness data.
