He aha nā ʻano hoʻomākaukau a me nā hiʻohiʻona hana o ka CVD silicon carbide coating?

ʻO CVD (Chemical Vapor Deposition) kahi ʻano hana maʻamau no ka hoʻomākaukau ʻana i nā uhi carbide silika.ʻO nā uhi kalapona kilikaki CVDloaʻa nā hiʻohiʻona hana kū hoʻokahi. E hoʻolauna kēia ʻatikala i ke ʻano hoʻomākaukau o ka CVD silicon carbide coating a me kāna mau hiʻohiʻona hana.

1. Ka hoomakaukau ana oʻO ka uhi ʻana o ka carbide silikon CVD
Hoʻololi ke ʻano CVD i nā precursors kinoea i loko o nā uhi carbide silika paʻa ma lalo o nā kūlana wela kiʻekiʻe. E like me nā ʻokoʻa kinoea precursors, hiki ke hoʻokaʻawale ʻia i loko o ka pae kinoea CVD a me ka pae wai CVD.

1. Māhele mahu CVD
Hoʻohana ʻo CVD i nā mea kinoea, maʻamau i nā pūhui organosilicon, e hoʻokō i ka ulu ʻana o nā kiʻiʻoniʻoni silicon carbide. ʻO nā pūhui organosilicon maʻamau ka methylsilane, dimethylsilane, monosilane, a me nā mea ʻē aʻe, e hana ana i nā kiʻiʻoniʻoni silicon carbide ma nā substrate metala ma o ka lawe ʻana i nā precursors kinoea i loko o nā keʻena hopena wela. ʻO nā wahi wela kiʻekiʻe i loko o ke keʻena pane e hana pinepine ʻia e ka hoʻomehana induction a i ʻole ka hoʻomehana resistive.

2. Māhele wai CVD
Hoʻohana ʻia ka CVD-phase wai i ka wai precursor, maʻamau he mea hoʻoheheʻe organik i loaʻa i ke silikoni a me kahi pūhui silanol, i hoʻomehana ʻia a hoʻoheheʻe ʻia i loko o ke keʻena pane, a laila hoʻokumu ʻia kahi kiʻiʻoniʻoni silicon carbide ma ka substrate ma o ka hopena kemika.

2. Nā hiʻohiʻona hana oʻO ka uhi ʻana o ka carbide silikon CVD

1.Excellent kiʻekiʻe wela hana
ʻO nā uhi kalapona kilikaki CVDhāʻawi maikaʻi loa i ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa oxidation. Hiki iā ia ke hana ma nā wahi wela kiʻekiʻe a hiki ke kū i nā kūlana koʻikoʻi i nā wela kiʻekiʻe.

2.Good mechanical waiwai
ʻO ka uhi ʻana o ka carbide silikon CVDhe kiʻekiʻe ka paʻakikī a me ke kūpaʻa maikaʻi. Mālama ia i nā substrate metala mai ka ʻaʻahu a me ka ʻino, e hoʻolōʻihi i ke ola lawelawe o ka mea.

3. Paʻa kemika maikaʻi loa
ʻO nā uhi kalapona kilikaki CVDkū'ē nui i nā kinikona maʻamau e like me nā waikawa, nā alkali a me nā paʻakai. Kūʻē ia i ka hoʻouka ʻana a me ka corrosion o ka substrate.

4. Haʻahaʻa friction coefficient
ʻO ka uhi ʻana o ka carbide silikon CVDhe haʻahaʻa friction coefficient a maikaʻi pono-lubricating waiwai. Hoʻemi ia i ka friction a me ka ʻaʻahu a hoʻomaikaʻi i ka pono o ka hoʻohana waiwai.

5.Good thermal conductivity
He maikaʻi nā waiwai conductivity wela o ka CVD silicon carbide coating. Hiki iā ia ke alakaʻi wikiwiki i ka wela a hoʻomaikaʻi i ka maikaʻi o ka hoʻoheheʻe wela o ke kumu metala.

6.Excellent uila insulation waiwai
Loaʻa i ka CVD silicon carbide coating nā waiwai insulation uila a hiki ke pale i ka leaka o kēia manawa. Hoʻohana nui ia i ka pale insulation o nā mea uila.

7. Hiki ke hoʻololi i ka mānoanoa a me ka haku mele
Ma ka hoʻomalu ʻana i nā kūlana i ka wā o ke kaʻina CVD a me ka neʻe ʻana o ka precursor, hiki ke hoʻoponopono ʻia ka mānoanoa a me ka hoʻohui ʻana o ke kiʻi carbide silicon. Hāʻawi kēia i nā koho he nui a me ka maʻalahi no nā noi like ʻole.

I ka pōkole, ʻo ka CVD silicon carbide coating he mea maikaʻi loa ka hana wela kiʻekiʻe, nā waiwai mechanical maikaʻi loa, ke kūpaʻa kemika maikaʻi, ka helu haʻahaʻa haʻahaʻa, ka conductivity thermal maikaʻi a me nā waiwai insulation uila. Hoʻohana nui kēia mau waiwai i ka CVD silicon carbide coatings i hoʻohana nui ʻia i nā kula he nui, me ka uila, optics, aerospace, chemical industry, etc.
