Ua maopopo ka paakiki otungsten carbideʻoi aku ka kiʻekiʻe ma mua o nā metala maʻamau, a ʻo ka paʻakikī kiʻekiʻe a me ke kūpaʻa lole kiʻekiʻe nā hiʻohiʻona nui o nā huahana carbide.A laila lilo ka ho'āʻo paʻakikī no kēlā me kēia pūʻulu o nā huahana i mea nui e hōʻoia i ka paʻakikī o nā huahana.
E ho'āʻo ʻia kēlā me kēia pūʻulu o nā huahana o kā mākou hui ma ka hoʻāʻo ʻana i nā ʻāpana laʻana e ʻike inā ʻoi aku ka paʻakikī o Rockwell i ke kūlana.I mea e hōʻoiaʻiʻo ai i ka pololei o ke ana ʻana, ʻo ka ʻili o ka huila e hoʻoheheʻe ʻia ma kahi o 0.2 mm ma mua o ke ana ʻana, a ʻoi aku ka liʻiliʻi o ka roughness Ra i ka 0.2 micron.Ma muli o ke kiʻekiʻe o ka paʻakikī o ka carbide, ua maʻalahi ka indenter daimana, no laila ua hoʻāʻo ʻia ka indenter daimana ma mua o ka hoʻāʻo e hōʻoia i ka pololei o ke ana.
Hiki i ka ho'āʻo paʻakikī ke hōʻike i nā waiwai mechanical a me nā ʻokoʻa o nā mea carbide ma lalo o nā ʻano kemika like ʻole, ka ʻenehana hana.Hiki ke hoʻohana ʻia nā huahana kūpono i nā ʻano hana koʻikoʻi a pāʻani i kāna hana kiʻekiʻe.
Hoʻokumu paʻa ʻo Ltd. i ka ʻike "ʻoi aku ka maikaʻi, ka mea kūʻai mua", mālama i ka maikaʻi o ka huahana ʻaʻole ʻoluʻolu a hoʻoikaika no ka hemolele.Hoʻoholo mākou e hana i ka maikaʻi maikaʻi loanā huahana tungsten carbide.
