Nā noi a me nā mākeke o ka tantalum carbide coatings

ʻO Tantalum carbide paʻakikī, kiʻekiʻe heheʻe helu, kiʻekiʻe wela hana, hoʻohana nui ʻia e like me ka mea hoʻohui paʻa. Hiki ke hoʻomaikaʻi maikaʻi ʻia ka paʻakikī wela, ke kūpaʻa haʻalulu wela a me ka pale ʻana o ka oxidation thermal o ka carbide cemented ma o ka hoʻonui ʻana i ka nui o ka tantalum carbide. No ka manawa lōʻihi, hoʻohui ʻia kahi carbide tantalum hoʻokahi i ka tungsten carbide (a i ʻole tungsten carbide a me ka titanium carbide), a hui pū ʻia ka mea hoʻopaʻa paʻa cobalt metala, hana ʻia, hoʻopaʻa ʻia e hana i ka alloy paʻakikī. I mea e hōʻemi ai i ke kumukūʻai o ka paʻa paʻa, hoʻohana pinepine ʻia ka tantalum niobium compound carbide. I kēia manawa, ʻo ka hoʻohana mua ʻana o ka pūhui tantalum niobium: TaC: NbC ʻo 80:20 a me 60:40, a ʻo ka ikehu o ka niobium carbide i loko o ka paʻakikī a hiki i 40% (maʻamau ʻaʻole ʻoi aku ma mua o 20% ʻoi aku ka maikaʻi).
