Izindlela zokuhlola ubulukhuni beRockwell Knoop kanye neVickers ze-aluminium nitride ceramics kanye nezindlela zokuhlola ama-bearings ensimbi ajikelezayo

1. Indlela yokuhlola ubulukhuni beRockwell Knoop Vickers ye-aluminium nitride ceramics
Njengoba izinto zobumba zinesakhiwo esiyinkimbinkimbi, ziqinile futhi zithambile ngokwemvelo, futhi zine-deformation encane yepulasitiki, izindlela zokuveza ubulukhuni ezisetshenziswa kakhulu zifaka phakathi ubulukhuni beVickers, ubulukhuni beKnoop kanye nobunzima beRockwell. IShancai Company inezinhlobonhlobo zabahloli bobulukhuni, abanezivivinyo ezahlukene zobulukhuni kanye nabahloli bobulukhuni abahlukahlukene abahlobene.
Izindinganiso ezilandelayo zingasetshenziswa njengereferensi:
Ukuhlolwa Kokuqina Kwezinto Zensimbi ze-GB/T 230.2 Rockwell:
Kunezikali eziningi zokuqina kweRockwell, futhi izinto zobumba ngokuvamile zisebenzisa izikali ze-HRA noma ze-HRC.
Ukuhlolwa kobulukhuni be-Metal Vickers kwe-GB/T 4340.1-1999 kanye nokuhlolwa kobulukhuni be-Metal Knoop kwe-GB/T 18449.1-2001.
Izindlela zokulinganisa i-Knoop ne-Micro-Vickers ziyafana ngokuyisisekelo, umehluko uwukuthi kusetshenziswe ama-indenter ahlukene.
Kuyaphawuleka ukuthi ngenxa yohlobo olukhethekile lomkhiqizo, singasusa ukugoba kwe-Vickers okungavumelekile ngokwesimo sokugoba ngesikhathi sokulinganisa ukuze sithole idatha enembile kakhudlwana.
2. Izindlela zokuhlola amabheringi ensimbi ajikelezayo
Ngokwezindlela zokuhlola ubulukhuni bezingxenye zensimbi nezinsimbi ezingezona insimbi ezichazwe ku-JB/T7361-2007, kunezindlela eziningi zokuhlola ngokwenqubo yokusebenza, zonke ezingahlolwa ngesihloli sobulukhuni seShancai:
1） Indlela yokuhlola ubulukhuni bukaVickers
Ngokuvamile, izingxenye zokuthwala eziqiniswe ebusweni zihlolwa ngendlela yokuhlola ubulukhuni be-Vickers. Kufanele kunakwe ukuqeda ubuso bento yokusebenza kanye nokukhethwa kwamandla okuhlola.
2） Indlela yokuhlola ubulukhuni beRockwell
Ukuhlolwa kobulukhuni okuningi kweRockwell kwenziwa kusetshenziswa isikali se-HRC. Umhloli wobulukhuni weShancai Rockwell useqoqe iminyaka eyi-15 yesipiliyoni futhi angahlangabezana nazo zonke izidingo.
3） Indlela yokuhlola ubulukhuni beLeeb
Ukuhlolwa kobulukhuni be-Leeb kungasetshenziswa kuma-bearings afakiwe noma okunzima ukuwahlukanisa. Ukunemba kwawo kokulinganisa akukuhle njengokwe-benchtop hardness tester.
Leli zinga lisebenza kakhulu ekuhlolweni kobulukhuni bezingxenye zensimbi ezithwala izinsimbi, izingxenye zensimbi ezifakwe insimbi ezithambile nezithambile kanye nezingxenye zensimbi eziqediwe kanye nezingxenye zensimbi ezithwala izinsimbi ezingezona insimbi.
