1. Shandisa Vickers hardness tester yewelded parts (Weld Vickers hardness test) nzira:
Sezvo microstructure yejoint part of the weldment (weld seam) panguva yewelding ichachinja panguva yekugadzira, inogona kuumba chisungo chisina simba muhutano hwakasungirirwa.Kuomarara kwewelding kunogona kuratidza zvakananga kana iyo welding process inonzwisisika.Ipapo iyo Vickers kuomarara Nzira yekuongorora inzira inobatsira kuongorora kunaka kwewelds.Iyo Vickers kuomarara tester yeLaizhou Laihua Hardness Tester Factory inogona kuita kuyedza kuomarara pazvikamu zvakashongedzwa kana nzvimbo dzewelding.Paunenge uchishandisa Vickers kuomarara tester kuyedza zvikamu zvakasungwa, zvinotevera bvunzo mamiriro anofanirwa kucherechedzwa:
Kupfava kwesample: Tisati tayedzwa, tinokuya weld kuti iongororwe kuti iite kuti nzvimbo yayo itsetseke, isina oxide layer, makatsemuka uye humwe hurema.
Pamutsetse wepakati we weld, tora poindi pane yakakombama 100 mm yega yekuyedza.
Kusarudza masimba ekuedza akasiyana kunozokonzera mhedzisiro dzakasiyana, saka isu tinofanirwa kusarudza rakakodzera bvunzo simba tisati taedza.
2. Mashandisiro eVickers hardness tester (micro Vickers hardness tester) kuti aone kudzika kweiyo yakaoma layer?
Maitiro ekuona kudzika kweiyo yakaomeswa simbi yezvikamu zvesimbi nekugadziriswa kwepamusoro senge carburizing, nitriding, decarburization, carbonitriding, nezvimwewo, uye zvikamu zvesimbi zvakadzimwa?
Iyo inoshanda yakaomeswa yakaomeswa kudzika kunonyanya kushandiswa kudziya kwenzvimbo kukonzeresa shanduko uye kuita shanduko pamusoro pesimbi kuti iwane mhedzisiro yekuwedzera kuoma uye kusimba uye kuoma.Rinoreva kuyerwa kubva kugwara rechikamu chepamusoro kusvika kumuganhu wemicrostructure wakatarwa.Kana iyo yakaomeswa dhizaini chinhambwe cheyakataurwa microhardness.Kazhinji isu tinoshandisa iyo gradient kuomarara nzira yeVickers kuomarara tester kuona inoshanda yakaomeswa kudzika kweiyo workpiece.Nheyo ndeyekuona iyo inoshanda yakaomeswa yakaomeswa kudzika kwakavakirwa pakuchinja kweiyo micro-Vickers kuomarara kubva kumusoro kusvika pakati pechikamu.
Kune dzakanangana nzira dzekushanda, ndapota tarisa kune yekambani yedu Vickers hardness tester oparesheni vhidhiyo.Izvi zvinotevera sumo yekushanda iri nyore:
Gadzirira sampuli sezvinodiwa, uye nzvimbo yekuyedza inofanirwa kukwenenzverwa kune girazi repamusoro.
Sarudza simba rekuedza reVickers hardness tester.Kuomarara kwegradient kunoyerwa panzvimbo mbiri kana kupfuura.Kuoma kweVickers kunoyerwa pane imwechete kana kupfuura mitsara yakafanana perpendicular kumusoro.
Kudhirowa kuomarara curve zvichibva pane yakayerwa data, zvinogona kuzivikanwa kuti yakatwasuka chinhambwe kubva pamusoro pechikamu kusvika ku550HV (kazhinji) ndiko kudzika kwakaomarara kwakaomarara.
3. Mashandisiro ekushandisa Vickers kuomarara tester yekutyoka kuomarara kwekuyedza (kutsemuka kusimba Vickers kuomarara nzira yekuyedza)?
Kutyoka kusimba ndiko kukosha kwekupokana kunoratidzwa nechinhu kana sampuli kana chikamu chinotsemuka pasi pemamiriro asina kugadzikana senge makatsemuka kana kutsemuka-kunge hurema.
Kuomarara kwefracture kunomiririra kugona kwechinhu kudzivirira kupararira kwekuputika uye chiratidzo chehuwandu hwekuoma kwechinhu.
Paunenge uchiita bvunzo yekutyoka kwekuomarara, tanga waposhesa pamusoro peiyo sampu yebvunzo kune yegirazi pamusoro.PaVickers hardness tester, shandisa conical diamond indenter yeVickers hardness tester kuita indentation panzvimbo yakakwenenzverwa ine mutoro we10Kg.Kutsemuka kwakafanogadzirwa kunogadzirwa pamakona mana echiratidzo.Isu tinowanzo shandisa Vickers hardness tester kuti tiwane fracture toughness data.
