Pehea e koho ai i nā mea hana paʻi a me ka uhi?

Ke paʻi mākou i nā kaula, nui nā ʻano o nā pai āu e koho ai.Pehea mākou e koho ai iā lākou?E like mepaʻi kila paʻakikī， paʻi i ka hao, a i ʻole ka alumini, pehea mākou e hana ai?

1. Ke kila kiʻekiʻe-wikiwiki: I kēia manawa hoʻohana nui ʻia e like me nā mea tap, e like me M2 (W6Mo5Cr4V2, 6542), M3, etc., kapa mākou iā HSS.

2. Cobalt kila kiʻekiʻe-wikiwiki: I kēia manawa hoʻohana nui ʻia e like me nā mea tap, e like me M35, M42, etc., ua kapa ʻia ʻo HSS-E.

3. ʻO ka pauka metallurgy kila kiʻekiʻe: hoʻohana ʻia ma ke ʻano he mea paʻi kiʻekiʻe, ʻoi aku ka maikaʻi o kāna hana i ka hoʻohālikelike ʻana i nā mea ʻelua ma luna, a ʻokoʻa hoʻi nā ʻano inoa o kēlā me kēia mea hana, me ke code marking he HSS-E-PM. .

4. Tungsten carbide: koho maʻamau i ka ultrafine carbide grade, ka mea nui i hoʻohana ʻia no ka hana ʻana i ka hoʻoheheʻe ʻana i nā mea ʻoki pōkole pōkole, e like me nā paipu carbide no ka hao hina hina, nā paipu carbide no ke kila paʻakikī,ka paipa carbide no ka alumini, etc., kapa mākou he carbide paipa.

ʻO nā kīʻaha kaula

hilinaʻi nui i nā mea waiwai, a ʻo ke koho ʻana i nā mea maikaʻi e hiki ke hoʻonui i nā ʻāpana hoʻonohonoho o ka paʻi, e kūpono ai no nā kūlana hana kūpono a ʻoi aku ka koʻikoʻi, ʻoiai ʻoi aku ka lōʻihi o ke ola.

Ka uhi ʻana o ka paipa

1. Steam oxidation: Hoʻokomo ʻia ka paipa i loko o ka mahu wai wela e hana i kahi ʻāpana o ke kiʻi ʻoniʻoni ma luna o kona ʻili, kahi adsorption maikaʻi ma ka coolant a hiki ke hoʻemi i ka friction, ʻoiai e pale ana i ka hoʻopili ʻana ma waena o ka tap a me ka mea i ʻoki ʻia.He kūpono no ka hana ʻana i ke kila palupalu.

2. Hoʻomaʻamaʻa Nitriding: Hoʻopili ʻia ka ʻili o ka tap e hana i kahi papa paʻakikī o ka ʻili, kūpono no ka hana ʻana i nā mea hana e like me ka hao a me ka alumini hoʻoheheʻe i loaʻa ke kūpaʻa kiʻekiʻe i ka ʻoki ʻana.

3. TiN: Ka uhi melemele gula, me ka paʻakikī o ka uhi ʻana a me ka lubricity maikaʻi, a me ka hana adhesion hoʻopili maikaʻi, kūpono no ka hana ʻana i ka hapa nui o nā mea.

4. TiCN: Ka uhi hina polū, me ka paakiki ma kahi o 3000HV a me ka pale wela a hiki i 400 ° C.

5. TiN + TiCN: ʻO ka uhi melemele hohonu me ka paʻakikī paʻakikī a me ka lubricity maikaʻi, kūpono no ka hana ʻana i ka hapa nui o nā mea.

6. TiAlN: Ka uhi polū hina, paʻakikī 3300HV, pale wela a hiki i 900 ° C, kūpono no ka mīkini kiʻekiʻe.

7. CrN: ʻO ke kala hina hina me ka hana lubrication maikaʻi loa, hoʻohana nui ʻia no ka hana ʻana i nā metala non-ferrous.
