Nā hiʻohiʻona a me ka hoʻohana ʻana o Rockwell hardness tester

ʻO ka hoʻāʻo ʻana o Rockwell hardness tester kekahi o nā ʻano hana maʻamau ʻekolu o ka hoʻāʻo paʻakikī.

ʻO nā hiʻohiʻona kiko'ī penei:

1) ʻOi aku ka maʻalahi o ka hoʻāʻo paʻakikī ʻo Rockwell ma mua o Brinell a me Vickers hardness tester, hiki ke heluhelu pololei ʻia, e lawe mai ana i ka pono hana kiʻekiʻe.

2) Hoʻohālikelike ʻia me ka hoʻāʻo paʻakikī ʻo Brinell, ʻoi aku ka liʻiliʻi o ka indentation ma mua o ka Brinell hardness tester, no laila ʻaʻohe mea pōʻino i ka ʻili o ka mea hana, ʻoi aku ka maikaʻi no ka ʻike ʻana i nā ʻāpana i hoʻopau ʻia o ka ʻoki ʻana i nā mea hana. , mea paahana, etc.

3) Ma muli o ka mana pre-detection o Rockwell hardness tester, ʻoi aku ka liʻiliʻi o ka mana o ka liʻiliʻi o ka ʻili i ka waiwai paʻakikī ma mua o Brinell a me Vickers, a ʻoi aku ka maikaʻi no ka hana nui o ka mīkini a me ka metallurgical thermal processing a me semi- ka nānā ʻana i nā huahana i hoʻopau ʻia.

4) Loaʻa iā ia kahi haʻahaʻa liʻiliʻi o ka Rockwell hardness tester i ka hoʻāʻo ʻana, hiki ke hoʻohana ʻia no ka hoʻāʻo ʻana i ka paʻakikī o ka papa hoʻopaʻapaʻa pāpaʻu a i ʻole ka papa uhi uhi.
