電解プラズマ酸化処理法によるセラミックスコーティング技術

摘要

Recently, technologies of plasma electrolytic oxidation (PEO) coatings are being increasingly used for the surface treatments of light metals in industries. This paper, Parker ceramics coatings (PCC) of zirconia ceramics system, one of the PEO processes, is introduced. For numerous tribological applications, the PCC can greatly improve the wear resistance, thermal resistance, and corrosion resistance of the light metals with controllable roughness and hardness of the coatings. This technology creates new possibilities of using light metals for sliding parts in automobile industries, and is expected to have a profund influence for future applications of light metals in other areas.%近年，産業分野における環境への配慮，省エネルギー化への要望は極めて高く，自動車や各種産業機械の多くの部品にはリサイクル性，小型化，軽量化が望まれている．アルミニウム，マグネシウム，チタニウムは，それら要望を満足する材料として最も期待され，その需要は急速に拡大している．
