ʻO ka Universal hardness tester he mea hana hoʻāʻo piha e pili ana i nā kūlana ISO a me ASTM, e ʻae ana i nā mea hoʻohana e hana i nā hoʻāʻo paʻakikī ʻo Rockwell, Vickers a me Brinell ma ka mea kani like.Hoʻāʻo ʻia ka Universal hardness tester ma muli o nā loina Rockwell, Brinell, a me Vickers ma mua o ka hoʻohana ʻana i ka pilina hoʻololi o ka ʻōnaehana paʻakikī e loaʻa ai nā waiwai paʻakikī.
He kūpono ka pālākiō paʻakikī HB Brinell no ke ana ʻana i ka paʻakikī o ka hao hoʻoheheʻe ʻia, nā huila non-ferrous, a me nā kila annealed like ʻole.ʻAʻole kūpono ia no ke ana ʻana i nā laʻana a i ʻole nā mea hana paʻakikī, liʻiliʻi loa, ʻeleʻele, ʻaʻole e ʻae i nā indentations nui ma ka ʻili.
He kūpono ka pālākiō paʻakikī HR Rockwell no: hoʻāʻo ʻana i nā ʻōpala, ana paʻakikī o nā ʻāpana i hoʻopaʻa ʻia, kinai ʻia a me ka wela wela.
He kūpono ka pālākiō paʻakikī HV Vickers no: ke ana ʻana i ka paʻakikī o nā laʻana a me nā ʻāpana me nā wahi liʻiliʻi a me nā waiwai paʻakikī kiʻekiʻe, ka paʻakikī o nā ʻāpana infiltrated a i ʻole nā uhi ma hope o ka mālama ʻana i ka ʻili, a me ka paʻakikī o nā mea lahilahi.
ʻO kēia ka hoʻolauna ʻana i ka moʻo hou o nā mea hōʻike paʻakikī Universal: a me ka pale paʻi Universal Hardness Tester
ʻOkoʻa mai ka Universal hardness tester kuʻuna, hoʻohana ka hanauna hou Universal hardness tester i ka ʻenehana sensor a me ka ʻōnaehana manaʻo hoʻopaʻa paʻa e pani i ke kumu hoʻohālikelike, e maʻalahi ke ana a ʻoi aku ka paʻa o ke ana.
