ʻoʻoleʻa:

Hoʻohana mau ʻia nā paipu kila kila e ana i ka paʻakikī o Brinell, Rockwell a me Vickers.ʻO ka paʻakikī Brinell Ma waena o nā kūlana paipu kila, ʻo Brinell hardness ka mea i hoʻohana nui ʻia, a ʻo ka paʻakikī o ka mea i hōʻike pinepine ʻia e ke anawaena indentation, ʻo ia ka intuitive a me ka maʻalahi.Eia naʻe, ʻaʻole kūpono ia no nā paipu kila o ke kila ʻoi aku ka paʻakikī a ʻoi aku ka lahilahi.

ʻO ka paʻakikī o Rockwell:

ʻO ka hoʻāʻo paʻakikī ʻo Rockwell paipu kila kila me ka hoʻāʻo paʻakikī Brinell.ʻO ka ʻokoʻa, ʻo ia ke ana i ka hohonu o ka indentation.ʻO ka hoʻāʻo paʻakikī ʻo Rockwell kahi ala i hoʻohana nui ʻia i hoʻohana ʻia ʻo HRC i ka lua wale nō ma mua o Brinell hardness HB i nā kūlana paipu kila.Hiki ke hoʻohana ʻia ka paʻakikī Rockwell i ka hoʻoholo ʻana i nā mea metala mai ka palupalu loa a i ka paʻakikī loa.Hoʻopili ia i ke ʻano Brinell.ʻOi aku ka maʻalahi ma mua o ke ʻano Brinell a hiki ke heluhelu pololei i ka waiwai paʻakikī mai ke kelepona o ka mīkini paʻakikī.Eia naʻe, ma muli o kona liʻiliʻi liʻiliʻi, ʻaʻole pololei ka waiwai paʻakikī e like me ke ʻano Brinell.

ʻO ka paʻakikī o Vickers

ʻO ka hoʻāʻo paʻakikī ʻo Vickers tube kila he ʻano hoʻāʻo indentation no ke ana ʻana i nā mea metala lahilahi a me ka paʻakikī o ka papa honua.Loaʻa iā ia nā pono nui o nā ʻano Brinell a me Rockwell, a lanakila i kā lākou mau hemahema kumu, akā ʻaʻole maʻalahi ia e like me ke ʻano Rockwell.ʻAʻole hoʻohana ʻia ke ʻano Vickers i nā kūlana paipu kila.

Hoao paakiki

He 6.0mm a ʻoi aʻe ke anawaena o ka paipu kila kuhili ʻole a me ka paipu kila kuhiliʻole annealed me ka mānoanoa pā o 13mm a i ʻole ka liʻiliʻi.Hiki iā ia ke hōʻike paʻakikī W-B75 ʻano Vickers.He wikiwiki loa a maʻalahi hoʻi e hoʻāʻo a kūpono no ka nānā wikiwiki a me ka ʻole o ka luku ʻana i nā paipu kila kila.ʻO nā paipu kila kila me ke anawaena o loko o ka ʻoi aku ma mua o 30 mm a me ka mānoanoa o ka pā i ʻoi aku ma mua o 1.2 mm e hoʻāʻo ʻia me kahi hōʻike paʻakikī Rockwell e hoʻāʻo ai i ka paʻakikī HRB a me HRC.ʻO nā paipu kila kila me ke anawaena o loko o ʻoi aku ma mua o 30 mm a me ka mānoanoa o ka pā ma lalo o 1.2 mm e hoʻāʻo ʻia me kahi mea hōʻike paʻakikī ʻo Rockwell e hoʻāʻo ai i ka HRT a i ʻole HRN paʻakikī.No nā paipu kila kila me ke anawaena o loko o lalo o 0 mm a ʻoi aku ma mua o 4.8 mm, ua hoʻāʻo ʻia ka paʻakikī o HR15T e kahi mea hōʻike paʻakikī Rockwell kūikawā no nā paipu.Ke ʻoi aku ka nui o ke anawaena o loko o ka paipu kila kila ma mua o 26 mm, hiki ke hoʻāʻo ʻia ka paʻakikī o ka paia o loko o ka paipu e kahi Ro.
