ʻO nā ʻano hoʻāʻo paʻakikī ʻo Rockwell Knoop lāua ʻo Vickers no nā keramika alumini nitride a me nā ʻano hoʻāʻo no nā bearings wili metala.

1. ʻO ke ʻano hoʻāʻo paʻakikī ʻo Rockwell Knoop Vickers no nā keramika alumini nitride
Ma muli o ke ʻano paʻakikī o nā mea keramika, he paʻakikī a palupalu ke ʻano, a he liʻiliʻi ka deformation plastic, ʻo nā ʻano hōʻike paʻakikī i hoʻohana pinepine ʻia e komo pū me ka paʻakikī Vickers, ka paʻakikī Knoop a me ka paʻakikī Rockwell. Loaʻa i ka Shancai Company nā ʻano mea hoʻāʻo paʻakikī like ʻole, me nā hoʻāʻo paʻakikī like ʻole a me nā mea hoʻāʻo paʻakikī pili like ʻole.
Hiki ke hoʻohana ʻia nā kūlana ma lalo nei ma ke ʻano he kuhikuhi:
GB/T 230.2 Nā Mea Metala Hoʻāʻo Paʻakikī Rockwell:
Nui nā unahi paʻakikī Rockwell, a hoʻohana pinepine nā mea seramika i nā unahi HRA a i ʻole HRC.
Hoʻāʻo paʻakikī GB/T 4340.1-1999 Metal Vickers a me ka hoʻāʻo paʻakikī GB/T 18449.1-2001 Metal Knoop.
Ua like like nā ʻano ana o Knoop a me Micro-Vickers, ʻo ka ʻokoʻa ka ʻokoʻa o nā indenters i hoʻohana ʻia.
He mea kūpono ke hoʻomaopopo ʻana ma muli o ke ʻano kūikawā o ka huahana, hiki iā mākou ke wehe i nā indentations Vickers pono ʻole e like me ke kūlana o ka indentation i ka wā o ke ana ʻana e loaʻa ai ka ʻikepili pololei.
2. Nā ʻano hoʻāʻo no nā bearings wili metala
Wahi a nā ʻano hoʻāʻo paʻakikī no nā ʻāpana kila a me nā ʻāpana metala nonferrous i kuhikuhi ʻia ma JB/T7361-2007, he nui nā ʻano hoʻāʻo e like me ke kaʻina hana workpiece, hiki ke hoʻāʻo ʻia nā mea āpau me kahi mea hoʻāʻo paʻakikī Shancai:
1）ʻAno hoʻāʻo paʻakikī Vickers
Ma keʻano laulā, hoʻāʻo ʻia nā ʻāpana hali paʻakikī o ka ʻili e ke ʻano hoʻāʻo paʻakikī Vickers. Pono e uku ʻia ka maka i ka hoʻopau ʻana o ka ʻili o ka mea hana a me ke koho ʻana o ka ikaika hoʻāʻo.
2）ʻAno hoʻāʻo paʻakikī ʻo Rockwell
Hana ʻia ka hapa nui o nā hoʻāʻo paʻakikī Rockwell me ka hoʻohana ʻana i ka unahi HRC. Ua hōʻiliʻili ʻo Shancai Rockwell hardness tester i 15 mau makahiki o ka ʻike a hiki ke hoʻokō i nā pono āpau.
3）Ke ʻano hoʻāʻo paʻakikī Leeb
Hiki ke hoʻohana ʻia ka hoʻāʻo paʻakikī Leeb no nā bearings i hoʻokomo ʻia a paʻakikī paha e wehe. ʻAʻole maikaʻi kona pololei o ke ana ʻana e like me ka mea hoʻāʻo paʻakikī benchtop.
Hoʻohana nui ʻia kēia kūlana i ka hoʻāʻo paʻakikī o nā ʻāpana hali kila, nā ʻāpana hali annealed a me ka tempered a me nā ʻāpana hali i hoʻopau ʻia a me nā ʻāpana hali metala non-ferrous.
