Pehea e hoʻomaikaʻi ai nā huahana i uhi ʻia i ka tantalum carbide i ka pale ʻana o nā mea?

ʻO ka tantalum carbide coating kahi ʻenehana lapaʻau maʻamau i hoʻohana ʻia e hiki ke hoʻomaikaʻi nui i ke kūpaʻa corrosion o nā mea. Hiki ke hoʻopili ʻia ka uhi carbide Tantalum i ka ʻili o ka substrate ma o nā ʻano hoʻomākaukau like ʻole, e like me ka deposition chemical vapor, deposition vapor physical, sputtering, a me nā mea ʻē aʻe, e hana i kahi ʻāpana a me ka pale pale paʻa, e hoʻopaʻa pono i ka pilina ma waena o nā mea a me nā mea. ke kaiapuni, a laila e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion.

Eia kekahi mau hana nui no ka uhi ʻana i ka tantalum carbide e hoʻomaikaʻi i ka pale ʻana i ka corrosion o nā mea.
1. ʻO ka hopena o ka pale kaʻawale: ʻO ka tantalum carbide coating ka maikaʻi a me ka paʻakikī kiʻekiʻe, hiki ke hoʻokaʻawale maikaʻi i ka substrate mai ka hoʻopili ʻana me ka mea waho waho a pale i ka corrosion e nā mea corrosive e like me nā waikawa, alkalis, a me nā paʻakai. ʻO ka papa pale paʻa i hoʻokumu ʻia e ka tantalum carbide coating hiki ke hōʻemi i ka permeability o ka ʻili waiwai a pale i ke komo ʻana o ka media corrosive, a laila e hoʻomaikaʻi ai i ke kūpaʻa corrosion o ka mea.

2. Paʻa kemika: Loaʻa i ka Tantalum carbide coating ke kūpaʻa kemika kiʻekiʻe a hiki ke mālama i kona ʻano a me kāna hana me ka ʻole o nā loli nui ma lalo o nā kūlana kūlohelohe. ʻO ka Tantalum carbide kahi mea me ka inertness kemika kiʻekiʻe e hiki ke pale maikaʻi i ka erosion o nā media corrosive ikaika e like me nā waikawa, alkalis, a me nā oxidants. Eia kekahi, ma muli o ke kiʻekiʻe o ka paʻakikī a me ka haʻahaʻa haʻahaʻa haʻahaʻa o ka tantalum carbide coating, hiki iā ia ke hōʻemi i ka friction a me ka ʻaʻahu ma waena o ka mea a me ke kaiapuni a hoʻonui i ke ola lawelawe o ka mea.

3. Hiki ke ho'oponopono pono'ī: ʻO ka Tantalum i loko o ka tantalum carbide coating ka mea hiki ke hoʻoponopono iā ia iho. I ka wā e ʻānai ʻia ai ka uhi ʻana, ʻeha a ʻeha ʻia paha, hiki i ka tantalum ke hana me ka oxygen, chlorine a me nā mea ʻē aʻe i loko o ke ʻano corrosive e hana i nā pūhui tantalum e like me ka tantalum oxide a me ka tantalum chloride, e hoʻopiha i nā hemahema ma ka ʻili o ka uhi, a hoʻi hou. hana i kiʻi pale. Hiki i kēia hana hoʻoponopono ponoʻī ke hoʻolohi i ke kaʻina hana corrosion a hoʻopaneʻe i ka luku ʻana i ka uhi.

4. Conductivity: Tantalum carbide coating he conductivity maikaʻi a hiki ke hana i kahi papa pale electrochemical e pale ai i ke kahe ʻana o ka corrosion. Ke hoʻopau ʻia ka ʻili o ka uhi e ka mea corrosive medium, e hoʻopili ʻo tantalum i nā ion i loko o ke kaiapuni a puni e hana i kahi ʻokoʻa paʻa paʻa, pale i ka hele ʻana o ka corrosion i kēia manawa, a pēlā e pale ai i ka hopena corrosion.

5. Hoʻohui i nā mea hoʻohui: I mea e hoʻomaikaʻi hou ai i ka pale ʻana o ka corrosion o ka tantalum carbide coating, hiki ke hoʻohui ʻia nā mea hoʻohui i ka wā o ka hoʻomākaukau ʻana i ka uhi. No ka laʻana, hiki i ka hoʻohui ʻana i nā mea hoʻohui e like me ka potassium a me nā oxides ke hoʻoikaika i ka densification a me ka hoʻomaʻemaʻe ʻana i ka palaoa o ka uhi, hoʻomaikaʻi i ka paʻa o ka intracrystalline interface i ka uhi ʻana a me ka hiki ke kū i ka discreteness, a laila e hoʻomaikaʻi ai i ke kūpaʻa corrosion o ka uhi.

I ka pōkole, hiki i ka tantalum carbide coatings ke hoʻoikaika nui i ka pale ʻana i ka corrosion o nā mea ma o nā mīkini e like me ka hopena o ka pale kaʻawale, ke kūpaʻa kemika, ka hiki ke ho'ōla ponoʻī, ka conductivity a me ka hoʻohui. He waiwai hoʻohana koʻikoʻi kēia i nā kula he nui, e like me ka ʻoihana kemika, ikehu, aerospace, etc.
