Miedzo yakawanda yakajairika yeVickers hardness tester

 

1. Shandisa nzira yekuedza kuomarara kweVickers yezvikamu zvakasungirirwa (Weld Vickers hardness test):

Sezvo chimiro chechikamu chekubatana kwe weldment (weld seam) panguva ye welding chichichinja panguva yekuumbwa, chinogona kuumba chisungo chisina kusimba muchimiro che welded. Kuoma kwe welding kunogona kuratidza zvakananga kana maitiro e welding ari akakodzera. Saka Vickers hardness Nzira yekuongorora inzira inobatsira kuongorora mhando ye welds. Vickers hardness tester yeLaizhou Laihua Hardness Tester Factory inogona kuita bvunzo ye hardness pazvikamu zvakasungirirwa kana nzvimbo dze welding. Paunoshandisa Vickers hardness tester kuyedza zvikamu zvakasungirirwa, mamiriro ebvunzo anotevera anofanira kucherechedzwa:

Kufara kwemuenzaniso: Tisati taedza, tinokuya weld inofanira kuyedzwa kuti pamusoro payo pave pakanaka, pasina oxide layer, maburi nezvimwe zvinokanganisa.

Pakati pemutsetse we weld, tora poindi pamusoro wakakombama 100 mm yega yega kuti uedze.

Kusarudza simba rekuyedza rakasiyana kuchaita kuti pave nemigumisiro yakasiyana, saka tinofanira kusarudza simba rekuyedza rakakodzera tisati taedza.

2. Ungashandisa sei Vickers hardness tester (micro Vickers hardness tester) kuti uone kudzika kwechikamu chakaomarara?

Ungaziva sei kudzika kwechikamu chesimbi chakaomarara uchishandisa nzira yekurapa pamusoro senge carburizing, nitriding, decarburization, carbonitriding, nezvimwewo, uye zvikamu zvesimbi zvakadzimwa induction?

Kudzika kwechikamu chakaomarara kunonyanya kushandiswa kupisa pamusoro penzvimbo kuti zvikonzere shanduko dzechimiro uye mashandiro pamusoro pesimbi kuti pave nemhedzisiro yekuwedzera kuomarara, simba uye kusimba. Izvi zvinoreva kuyerwa kubva padivi rakamira rechikamu kusvika kumuganhu we microstructure yakatarwa. Kana daro rechikamu chakaomarara che microhardness yakatarwa. Kazhinji tinoshandisa nzira ye gradient hardness yeVickers hardness tester kuti tione kudzika kwechikamu chakaomarara. Nheyo ndeyekuona kudzika kwechikamu chakaomarara kunoshanda zvichibva pakuchinja kwe micro-Vickers hardness kubva pamusoro kusvika pakati pechikamu.

Kuti uwane nzira dzakananga dzekushandisa, ndapota tarisa vhidhiyo yekambani yedu yeVickers hardness tester operation. Inotevera i sumo iri nyore yekushanda:

Gadzirirai sampuro sezvinodiwa, uye nzvimbo yekuyedza inofanira kukweshwa kusvika panzvimbo yegirazi.

Sarudza simba rekuyedza remuyedzisi wekuomarara weVickers. Kuomarara kwekuomarara kunoyerwa panzvimbo mbiri kana kupfuura. Kuomarara kweVickers kunoyerwa pamutsetse mumwe kana kupfuura wakatarisana wakatarisana nepamusoro.

Kana tichitora curve yekuomarara zvichibva padata rakayerwa, zvinogona kuzivikanwa kuti daro rakamira kubva pamusoro pechikamu kusvika ku550HV (kazhinji) ndiro kudzika kwechikamu chakaomarara kunoshanda.

3. Ungashandisa sei Vickers hardness tester pakuongorora kusimba kwekukuvara (nzira yekuongorora kusimba kwekukuvara kwekukuvara kweVickers)?

Kusimba kwekutyoka ndiko kukosha kwekudzivirira kunoratidzwa nechinhu chacho kana chifananidzo kana chikamu chacho chikatyoka mumamiriro ezvinhu asina kugadzikana akadai sekutsemuka kana zvikanganiso zvakaita sekutsemuka.

Kusimba kwematombo kunomiririra kugona kwechinhu kudzivirira kupararira kwematombo uye chiratidzo chehuwandu hwekusimba kwechinhu.

Paunenge uchiita bvunzo yekusimba kwetsandanyama, tanga wapukuta pamusoro pemuenzaniso wekuyedza kuita girazi. Pamuchina wekuyedza kuomarara weVickers, shandisa conical diamond indenter yemuchina wekuyedza kuomarara weVickers kuti uite indentation pamusoro wakaporishwa nemutoro we10Kg. Mitswe yakagadzirwa kare inogadzirwa pamativi mana echiratidzo. Isu tinowanzo shandisa muchina wekuyedza kuomarara weVickers kuti tiwane data rekusimba kwetsandanyama.
