Nā Kaula Kila Alloy Tensile Kiʻekiʻe

lNā kila ikaika tensile kiʻekiʻe

No nā noi e koi ana i nā ikaika tensile kiʻekiʻe a me ka paʻakikī ma mua o nā kila kalapona aia kekahi mau kila alloy haʻahaʻa. Ua hoʻokaʻawale ʻia kēia mau mea he mau kila tensile kiʻekiʻe a i ʻole nā ​​​​kila kūkulu a me nā kila paʻakikī hihia. Loaʻa i nā kila ikaika tensile kiʻekiʻe nā hoʻohui alloying lawa e hiki ai ma o ka paʻakikī (ma o ka quench a me ka temper treatment) e like me kā lākou hoʻohui alloying.

lNā kila paʻakikī hihia (carburising)

ʻO nā kila paʻakikī hihia he hui o nā kila kalapona haʻahaʻa kahi i hoʻomohala ʻia ai kahi ʻāpana ʻili paʻakikī kiʻekiʻe (no laila ke ʻano o ka huaʻōlelo paʻakikī hihia) i ka wā o ka mālama wela ʻana ma o ka omo ʻana a me ka hoʻolaha ʻana o ke kalapona. Kākoʻo ʻia ka ʻāpana paʻakikī kiʻekiʻe e ka ʻāpana kumu ma lalo i hoʻopilikia ʻole ʻia, ʻo ia ka paʻakikī haʻahaʻa a me ka paʻakikī kiʻekiʻe.

Ua kaupalena ʻia nā kila kalapona maʻemaʻe i hiki ke hoʻohana ʻia no ka hoʻopaʻakikī ʻana i ka hihia. Ma kahi e hoʻohana ʻia ai nā kila kalapona maʻemaʻe, hiki i ka hoʻopau wikiwiki ʻana e pono ai e hoʻomohala i ka paʻakikī kūpono i loko o ka hihia ke hana i ka hoʻopilikia a ʻo ka ikaika e hiki ke hoʻomohala ʻia i loko o ke kumu he palena loa ia. ʻAe nā kila paʻakikī hihia alloy i ka maʻalahi o nā ʻano hoʻopau lohi e hōʻemi i ka hoʻopilikia a hiki ke hoʻomohala ʻia nā ikaika kumu kiʻekiʻe.

lNā kila nitriding

Hiki i nā kila nitriding ke loaʻa ka paʻakikī o ka ʻili kiʻekiʻe i hoʻomohala ʻia e ka omo ʻana o ka naikokene, ke hōʻike ʻia i kahi lewa nitriding ma nā mahana ma ka laulā o 510-530°C, ma hope o ka paʻakikī a me ka hoʻomaloʻo ʻana.

ʻO nā kila tensile kiʻekiʻe i kūpono no ka nitriding: 4130, 4140, 4150 a me 4340.
