Ka noi a me ka mākeke o ka tantalum carbide coating

Tantalum carbide paakiki, kiʻekiʻe heheʻe wahi, kiʻekiʻe wela hana, nui hoʻohana 'ia e like me ka cemented carbide additive. Hiki ke hoʻomaikaʻi maikaʻi ʻia ka paʻakikī o ka 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 titanium carbide), a hui pū ʻia ka cobalt metal binder, hana ʻia, a hoʻopaʻa ʻia e hana i ka carbide cemented. I mea e hōʻemi ai i ke kumukūʻai o ka carbide cemented, hoʻohana pinepine i ka tantalum niobium complex carbide, i kēia manawa ka hoʻohana nui ʻana o ka tantalum niobium complex: TaC: NbC ʻo 80:20 a me 60:40 ʻelua, niobium carbide i ka ikehu paʻakikī hiki i 40% ( manaʻo maʻamau ʻaʻole i ʻoi aku ma mua o 20% maikaʻi).
