Pehea e ʻike ai i ka paʻakikī a me ke kūpaʻa o ka ʻūlū niho

Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu ʻO ka paʻakikī ke ʻano kumu e pono ai ka mea pahi niho. No ka wehe ʻana i nā ʻāpana mai kahi ʻāpana hana, pono ka pahi serrated e ʻoi aku ka paʻakikī ma mua o ka mea hana. ʻO ka paʻakikī o ka ʻaoʻao ʻoki o ka pahi niho i hoʻohana ʻia no ka ʻoki ʻana i ka metala ma mua o 60hrc, a ʻo ke kūpaʻa ʻana i ka ʻaʻahu ʻo ia ka hiki o ka mea ke kūʻē i ka ʻaʻahu. Ma keʻano laulā, ʻo ka paʻakikī o ka mea pahi niho, ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka ʻaʻahu.

ʻO ke kiʻekiʻe o ka paʻakikī o nā wahi paʻakikī i loko o ka hui, ʻoi aku ka nui o ka helu, ʻoi aku ka liʻiliʻi o nā ʻāpana, a ʻoi aku ka like o ka hoʻolaha ʻana, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana. Pili pū ke kūpaʻa ʻana i ka hoʻohuihui kemika, ka ikaika, ka microstructure a me ka mahana o ka ʻāpana friction o ka mea.

Ikaika a me ke kūpaʻa kūpono I mea e kū ai ka pahi niho i ke kaomi nui a hana ma lalo o nā kūlana haʻalulu a me ka haʻalulu e hana pinepine ʻia i ka wā o ke kaʻina ʻoki me ka ʻole o ka haki ʻana a me ka haki ʻana, pono ka mea o ka pahi mechanical i ka ikaika a me ke kūpaʻa kūpono. Ke kūpaʻa wela kiʻekiʻe ʻO ke kūpaʻa wela ke kumu nui e ana i ka hana ʻoki o ka mea hoʻokomo niho.
Pili ia i ka hana o ka mea pahi niho e mālama i ka paʻakikī i ʻaelike ʻia, ke kūpaʻa ʻana i ka ʻaʻahu, ka ikaika a me ka paʻakikī ma lalo o nā kūlana wela kiʻekiʻe. Pono hoʻi ka mea pahi ʻano niho i ka hiki ʻole ke oxidized i ka mahana kiʻekiʻe a me ka hiki ke anti-adhesion a me ka anti-diffusion, ʻo ia hoʻi, pono ka mea i ke kūpaʻa kemika maikaʻi.

ʻO nā waiwai kino wela maikaʻi a me ke kūpaʻa haʻalulu wela ʻO ka ʻoi aku ka maikaʻi o ka conductivity thermal o ka mea pahi niho, ʻoi aku ka maʻalahi o ka wela ʻoki e hoʻokuʻu ʻia mai ka wahi ʻoki, he mea maikaʻi ia e hōʻemi i ka mahana ʻoki.
