Izindlela zokuhlola ubulukhuni be-Rockwell Knoop kanye ne-Vickers ye-aluminium nitride ceramics nezindlela zokuhlola zamabhering ensimbi.

1.Indlela yokuhlola ubulukhuni be-Rockwell Knoop Vickers ye-aluminium nitride ceramics
Njengoba izinto ze-ceramic zinesakhiwo esiyinkimbinkimbi, ziqinile futhi ziqinile ngokwemvelo, futhi zine-deformation encane yepulasitiki, izindlela zokubonisa ubulukhuni ezivame ukusetshenziswa zihlanganisa ubulukhuni be-Vickers, ubulukhuni be-Knoop kanye nobulukhuni be-Rockwell. I-Shancai Company inezinhlobonhlobo zokuhlola ubulukhuni, ezinokuhlolwa kokuqina okuhlukene kanye nabahloli bobulukhuni abahlukahlukene abahlobene.
Amazinga alandelayo angasetshenziswa njengereferensi:
I-GB/T 230.2 Metallic Materials Test Rockwell Hardness:
Kunezikali zokuqina ze-Rockwell eziningi, futhi izinto zobumba ngokuvamile zisebenzisa izikali ze-HRA noma ze-HRC.
I-GB/T 4340.1-1999 Metal Vickers ukuhlolwa kobulukhuni kanye nokuhlola ubulukhuni be-GB/T 18449.1-2001 Metal Knoop.
Izindlela zokulinganisa ze-Knoop kanye ne-Micro-Vickers ziyafana, umehluko yizikhombe ezihlukene ezisetshenziswayo.
Kuyaphawuleka ukuthi ngenxa yemvelo ekhethekile yomkhiqizo, singasusa ama-indent angavumelekile e-Vickers ngokuya ngesimo sokuhlehlisa ngesikhathi sokulinganisa ukuze sithole idatha enembe kakhudlwana.
2.Izindlela zokuhlola zensimbi ezigingqayo
Ngokwezindlela zokuhlola ubulukhuni bensimbi nezingxenye ezinensimbi ezingenayo insimbi ezicaciswe ku-JB/T7361-2007, kunezindlela eziningi zokuhlola ngokuya ngenqubo yesiqeshana sokusebenza, zonke ezingahlolwa ngesihloli sobulukhuni be-Shancai:
1）Indlela yokuhlola ubulukhuni be-Vickers
Ngokuvamile, izingxenye ezithwala kanzima zihlolwa ngendlela yokuhlola ubulukhuni be-Vickers. Ukunakwa kufanele kukhokhwe ekuqedeni okungaphezulu kwe-workpiece kanye nokukhethwa kwamandla okuhlola.
2）Indlela yokuhlola ubulukhuni be-Rockwell
Ukuhlolwa kokuqina kokuqina kwe-Rockwell kwenziwa kusetshenziswa isikali se-HRC. Umhloli wokuqina ka-Shancai Rockwell uqoqe isipiliyoni seminyaka engu-15 futhi angahlangabezana nazo zonke izidingo.
3) Indlela yokuhlola ubulukhuni be-Leeb
Ukuhlolwa kokuqina kwe-Leeb kungasetshenziselwa amabheringi afakiwe noma okunzima ukuwaqaqa. Ukunemba kokulinganisa kwayo akukuhle njengalokho komhloli wokuqina wokuqina kwebhentshi.
Leli zinga lisebenza ngokuyinhloko ekuhlolweni kokuqina kwezingxenye ezithwala insimbi, izingxenye ezinezimbobo eziqinile neziqinile kanye nezingxenye zokuthwala eziqediwe kanye nezingxenye ezinensimbi ezingenayo insimbi.
