Nā waiwai o ka laweʻana i nā kila

E pili ana i ka hana hana a me ka nānāʻana i ka loiloi oʻO ka laweʻana i ke kila, e lawe i ka kila kila e pono ai i nā waiwai e like me kēia:

1. E hoʻopili nui i ka ikaika a me ka ikaika

2. Pono ka laweʻana i ke kila kila i ka paʻakikī kiʻekiʻe a me keʻano o ka mālama wela ma hope o ka mālamaʻana i ka wela.

4.ʻO kekahi paʻakikī e pale ai i ka hōʻehaʻana i ka hōʻeha ma lalo o ka hopena hopena;

6.ʻO ka paleʻana o ka corrosione, i ka lewa a me ka lubricantʻaʻole pono e maʻalahi a maʻalahi paha e maloʻo, e mālama i ka luster

7. Hana maikaʻi hana, e like me ke anuanu Aia nā koi likeʻole no nā mea i loaʻa ma lalo o nā kūlana hana kūikawā. E like me ka paleʻana o ke kiʻekiʻe kiʻekiʻe, kū kū'ēʻana i ke kū'ēʻana, empact consistist, Antimagnetic a pēlā aku.

ʻO ka hoʻopiliʻana i ke ola momona o ke olaʻana o nā maʻi i mea koʻikoʻi i ka inhomogexity o keʻano a me nā waiwai o ke kilau. No laila, he hana mana no nā koi no ka hui i hoʻohana a me ka hui kumu. ʻO ka Microstoructure o ka laweʻana i ke kilokilo i keʻano lawelawe e hoʻopiliʻia me keʻano maikaʻi me ka carbide maikaʻi ma Matrix. Hiki i kēlā Microstructure ke hāʻawi i ka laweʻana i nā kila i nā waiwai i koiʻia. ʻElua mau koi nui no keʻano kumu mua: he maʻemaʻe kekahi, e pili ana i nā manaʻo o nā meaʻona ʻO ka lua ka lua o ka papaʻaina,ʻo ia ka mea e loaʻa ai nā meaʻoleʻole o nā mea metallic a me nā kāmela i nā crabied i loko o ke kila pono e hoʻokaʻawaleʻia. No lailaʻo ka maʻemaʻe o ka kila a me ka huiʻana o keʻano o keʻano he mau pilikia nui o ka maikaʻi o keʻano o ka cheel sweel.
