I-Rockwell Knoop kunye neVickers iindlela zokuvavanya ubulukhuni be-aluminium nitride ceramics kunye neendlela zokuvavanya iibheringi zentsimbi.

1.Rockwell Knoop Vickers indlela yokuvavanya ubulukhuni be-aluminiyam nitride ceramics
Ekubeni izinto ze-ceramic zinesakhiwo esiyinkimbinkimbi, zilukhuni kwaye zincinci ngokwendalo, kwaye zine-deformation encinci yeplastiki, iindlela zokubonisa ubulukhuni eziqhelekileyo ezisetyenziswayo ziquka ukuqina kweVickers, ukuqina kwe-Knoop kunye nokuqina kwe-Rockwell. Inkampani yaseShancai inoluhlu olubanzi lwabavavanyi bobulukhuni, kunye neemvavanyo ezahlukeneyo zobunzima kunye nabavavanyi bobulukhuni abahlukeneyo.
Le migangatho ilandelayo ingasetyenziswa njengereferensi:
I-GB/T 230.2 yeMathiriyeli yeMetallic Rockwell Hardness Test:
Zininzi izikali zobulukhuni be-Rockwell, kunye nemathiriyeli ye-ceramic ngokubanzi zisebenzisa izikali ze-HRA okanye ze-HRC.
Uvavanyo lwe-GB/T 4340.1-1999 Metal Vickers ubulukhuni kunye ne-GB/T 18449.1-2001 yovavanyo lobulukhuni beMetal Knoop.
Iindlela zokulinganisa i-Knoop kunye ne-Micro-Vickers ziyafana ngokusisiseko, umahluko zii-indenters ezahlukeneyo ezisetyenzisiweyo.
Kuyaphawuleka ukuba ngenxa yobume obukhethekileyo bemveliso, sinokususa i-indentations ye-Vickers engasebenziyo ngokwemeko ye-indent ngexesha lokulinganisa ukufumana idatha echanekileyo.
2.Iindlela zokuvavanya iibheringi zentsimbi
Ngokweendlela zokuvavanya ubulukhuni bentsimbi kunye neengxenye zentsimbi zentsimbi ezichazwe kwi-JB/T7361-2007, zininzi iindlela zovavanyo ngokwenkqubo yomsebenzi, zonke zinokuvavanywa ngomvavanyi wobulukhuni be-Shancai:
1）Indlela yokuvavanya ubulukhuni beVickers
Ngokubanzi, iindawo ezithwele umphezulu oqinileyo zivavanywa yindlela yokuvavanya ubulukhuni beVickers. Ingqalelo kufuneka ihlawulwe kwisiphelo somphezulu we-workpiece kunye nokukhethwa kwamandla okuvavanya.
2）Indlela yokuvavanya ubulukhuni beRockwell
Uninzi lweemvavanyo zobulukhuni beRockwell zenziwa kusetyenziswa isikali se-HRC. Umhloli wobulukhuni buka-Shancai Rockwell uqokelele iminyaka eyi-15 yamava kwaye unokwanelisa zonke iimfuno.
3）Indlela yokuvavanya ubulukhuni beLeeb
Uvavanyo lobulukhuni beLeeb lunokusetyenziselwa iibheringi ezifakelweyo okanye ekunzima ukuziqhawula. Ukuchaneka komlinganiselo wayo akulunganga njengaleyo yomvavanyi wobulukhuni be-benchtop.
Lo mgangatho usetyenziswa kakhulu kuvavanyo lobunzima bentsimbi yentsimbi, i-annealed kunye ne- tempered bearing parts kunye neendawo zokuthwala ezigqityiweyo kunye neengxenye zentsimbi ezingenayo i-ferrous.
