…It is a composite material of ceramics and metal, a compound word of cer (ceramics) and met (metal). It was created with the aim of combining the advantages of ceramics, such as hardness and heat resistance, with metal's toughness, and was originally attempted for use in jet aircraft turbine blades after World War II. Currently, it is used not only as a heat-resistant material, but also for tools, corrosion resistance, wear resistance, electrical contacts, etc. Depending on the type of ceramic, it is classified as oxide cermet, carbide cermet, boride cermet, nitride cermet, etc. … From [Titanium Carbide]…Sintered bodies made of metal oxides or carbides bound with cobalt Co or nickel Ni are generally called cermets, but in Japan, tool makers refer to these TiC-based tools when they say cermet tools. The word cermet is a combination of the English words for ceramics and metal. TiC has a higher hardness and melting point than tungsten carbide (WC), has excellent oxidation resistance and adhesion resistance, and has a low coefficient of friction with iron. … *Some of the terminology that mentions "cermet" is listed below.

…セラミックスと金属との複合材料で,セラミックスceramicsのcerと金属metalのmetとの複合語である。セラミックスの硬さ,耐熱性と金属の靱性(じんせい)という長所を組み合わせることを目的として作られたもので,元来は第2次大戦後ジェット機のタービン翼用に試みられた。現在は耐熱材料としてだけでなく,工具,耐食,耐摩耗,電気接点などを目的とした使い方がされている。セラミックスの種類によって酸化物サーメット,炭化物サーメット,ホウ化物サーメット,窒化物サーメットなどと分類される。… 【チタンカーバイド】より…金属の酸化物や炭化物などをコバルトCo,ニッケルNiなどで結合した焼結体を一般にサーメットと呼ぶが,日本の工具関係者では,サーメット工具といえばこのTiC基の工具を指す。なおサーメットcermetとは,セラミックスceramicsと金属metalの英語から合成した語である。TiCはタングステンカーバイドWCに比べて硬度・融点が高く,耐酸化性・耐溶着性に優れ,鉄との摩擦係数も低い。… ※「cermet」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
