Ukusuka kwi-HRC ukuya kwi-HV: Indlela yokuguqula nokutolika amaxabiso obunzima kwiiplate zeChromium Carbide Overlay

Xa kufikwa ekuvavanyeni ukusebenza kweipleyiti yokunxiba egqunywe yi-chromium carbide, ubulukhuni sesinye sezona zibonakaliso zibalulekileyo. Kodwa kwiimarike zehlabathi, iindlela ezahlukeneyo zovavanyo kunye neeyunithi zokulinganisa zihlala zibangela ukudideka phakathi kwabathengi, iinjineli, kunye nabaphathi beeprojekthi. Ukuqonda umahluko phakathi kwe-HRC (ubulukhuni beRockwell) kunye ne-HV (ubulukhuni beVickers), kunye nendlela yokutolika la maxabiso, kunokuchaphazela kakhulu ukhetho lwakho lwezinto, ingxoxo yamaxabiso, kunye nolindelo lokusebenza olugugileyo.

Kutheni Abathengi Bekhathalele Ukuguqulwa Kobunzima?

Amashishini kunye neendawo ezahlukeneyo zithanda iiyunithi ezahlukeneyo zokuqina. Umzekelo:

Abathengi baseMelika nabaseYurophu badla ngokucela amaxabiso eRockwell C (HRC).

Amaziko aseAsia nakwezobugcisa anokukhetha idatha yeVickers (HV), ingakumbi kuvavanyo lwemicroscope.

Njengomthengisi wehlabathi jikelele weepleyiti zokunxiba eziqinileyo, iWodon ihlala ifumana imibuzo efana nale:

"UkubaIpleyiti yokunxiba ye-CCOinikwe umlinganiselo we-60 HRC, buthini ubunzima beVickers obuhambelanayo?

Ukuphendula oku kufuna okungaphezulu nje kwesixhobo sokubala—kufuna ukuqonda umahluko kwimigaqo yovavanyo kunye nezakhiwo zezinto.

Ukuqonda i-HRC kunye ne-HV: Iindlela zovavanyo zichaziwe

1. Ubunzima beRockwell C (HRC)

Ilinganisa ubunzulu bokutsalwa okubangelwa yikhowuni yedayimani phantsi komthwalo oyintloko.

Iyakhawuleza kwaye iluncedo kuvavanyo lobulukhuni be-macroscopic, ingakumbi kwiimveliso zentsimbi.

Kuqhelekile kuvavanyo lomgca wemveliso lweendawo zokuguguleka kwepleyiti.

2. Ubunzima beVickers (HV)

Isebenzisa i-indenter ye-pyramidal yedayimani phantsi kwemithwalo emincinci.

Ilinganisa ubude obude be-diagonal bokutsalwa kwe-indentation ngokusebenzisa uhlalutyo lwe-optical.

Ilungele ukuhlola iindawo ezincinci, ingakumbi umaleko oqinileyo okanye amasuntswana e-chromium carbide ngamanye.

Nangona zombini zisebenza, zisebenza ngeenjongo ezahlukeneyo: I-HRC ibonisa ubulukhuni bomphezulu ngokubanzi, ngelixa i-HV inokunika ulwazi malunga nobunzima obuncinci kunye nomgangatho we-carbide.

I-HRC ukuya kwi-HV: Iindidi eziqhelekileyo zoGuqulo lweePlati zeChromium Carbide Overlay Wear

Nantsi itheyibhile yokuguqulwa elula esekelwe kwidatha yokuvavanya evela kwiipleyiti zokunxiba ezidityanisiweyo:

⚠ Qaphela: La maxabiso aqikelelwa. Ukuguqulwa ngqo komntu omnye komnye akuchanekanga ngenxa yokwahluka kweendlela zokuvavanya kunye nolwakhiwo lwezinto ezifakwe ileya.

Kutheni Singakwazi Ukuguqula i-HRC ibe yi-HV Kanye Kanye?

Kukho izizathu ezibalulekileyo ezininzi:

Iinkqubo zovavanyo ezahlukeneyo

I-HRC isebenzisa umlinganiselo wobunzulu; i-HV ixhomekeke kwii-diagonals ezibonakalayo.

Iimo ze-Indenter, iintlobo zomthwalo, kunye nendawo yovavanyo ziyahluka.

Imicimbi yoLwakhiwo lwezinto

A ipleyiti yokunxiba ye-bimetalliciqulethe amasuntswana e-chromium carbide aqinileyo afakwe kwintsimbi ethambileyo.

Ukuqina kunokwahluka kakhulu phakathi komphezulu, umphezulu ongaphantsi komhlaba, kunye nezinto ezisisiseko.

Iinguqu zoMvelisi

Iindlela ezahlukeneyo zokwenziwa kwe-alloy, iinkqubo zokuwelda, kunye nonyango lobushushu zichaphazela iziphumo zovavanyo.

Nokuba ngaphakathi kwebhetshi efanayo yeplate yokunxiba ye-chromium carbide, ukufundwa kwe-HV kunokuqala ukusuka kwi-600 ukuya kwi-1800, kuxhomekeke kwindawo ovavanya kuyo.

Ukuqina yinto ebalulekileyo, kodwa yinto enye kuphela yephazili xa ukhetha ipleyiti efanelekileyo yokunxiba i-chromium carbide overlay. Ukuqonda umahluko phakathi kwe-HRC kunye ne-HV, kunye nendlela yokuzitolika ngokuchanekileyo, kuqinisekisa ulindelo oluchanekileyo lokusebenza kunye nezigqibo ezingcono zokusetyenziswa.
