ʻO Rockwell Knoop a me Vickers nā ʻano hoʻāʻo paʻakikī no nā seramika nitride aluminika a me nā ʻano hoʻāʻo no nā bearings rolling metal.

1. ʻO Rockwell Knoop Vickers ke ʻano hoʻāʻo paʻakikī no nā seramika nitride aluminika
No ka mea he ʻano paʻakikī nā mea seramika, paʻakikī a palupalu i ke ʻano, a he liʻiliʻi liʻiliʻi ka hoʻololi ʻana, ʻo nā ʻano hōʻike paʻakikī i hoʻohana pinepine ʻia me Vickers hardness, Knoop hardness a me Rockwell hardness. Loaʻa i ka Shancai Company nā ʻano mea hōʻike paʻakikī, me nā hoʻāʻo paʻakikī like ʻole a me nā mea hōʻike paʻakikī e pili ana.
Hiki ke hoʻohana ʻia nā maʻamau e like me ke kuhikuhi:
GB/T 230.2 Mea Metala Ho'āʻo Paʻa ʻO Rockwell:
Nui nā unahi paʻakikī o Rockwell, a hoʻohana maʻamau nā mea seramika i nā unahi HRA a i ʻole HRC.
GB/T 4340.1-1999 Metal Vickers hoao paakiki a me GB/T 18449.1-2001 Metal Knoop hoao paakiki.
ʻO ke ʻano o ke ana ʻana o Knoop a me Micro-Vickers he ʻano like, ʻo ka ʻokoʻa ka ʻokoʻa i hoʻohana ʻia.
Pono e hoʻomaopopo ʻia ma muli o ke ʻano kūikawā o ka huahana, hiki iā mākou ke wehe i nā indentations Vickers invalid e like me ke kūlana o ka indentation i ka wā ana e loaʻa ai ka ʻikepili pololei.
2. ʻO nā ʻano hoʻāʻo no nā bearings ʻōwili metala
Wahi a nā ʻano hoʻāʻo paʻakikī no ke kila a me nā ʻāpana metala nonferrous i kuhikuhi ʻia ma JB/T7361-2007, nui nā ʻano hoʻāʻo e like me ke kaʻina hana hana, hiki ke hoʻāʻo ʻia ia mau mea āpau me kahi hōʻike paʻakikī Shancai:
1） ʻO ke ʻano hoʻāʻo paʻakikī o Vickers
ʻO ka maʻamau, hoʻāʻo ʻia nā ʻāpana paʻa paʻa o ka ʻili e ka Vickers hardness testing method. Pono e noʻonoʻo i ka hoʻopau ʻana o ka ʻili o ka mea hana a me ke koho ʻana i ka ikaika hoʻāʻo.
2） ʻO ke ʻano hoʻāʻo paʻakikī ʻo Rockwell
Hana ʻia ka hapa nui o nā hoʻāʻo paʻakikī o Rockwell me ka hoʻohana ʻana i ka pālākiō HRC. Ua hōʻiliʻili ʻo Shancai Rockwell hardness tester i 15 mau makahiki o ka ʻike a hiki ke hoʻokō pono i nā pono āpau.
3）Leeb ʻano hoʻāʻo paʻakikī
Hiki ke hoʻohana ʻia ka hoʻāʻo paʻakikī Leeb no nā bearings i hoʻokomo ʻia a paʻakikī paha e wehe. ʻAʻole maikaʻi ka pololei o kāna ana ʻana e like me ka mea hoʻāʻo paʻakikī benchtop.
Hoʻohana nui ʻia kēia maʻamau i ka hoʻāʻo ʻana o ka paʻakikī o nā ʻāpana lawe kila, nā ʻāpana a me nā mea i hoʻopaʻa ʻia a hoʻopau ʻia a me nā ʻāpana metala non-ferrous.
