目前，负载在金属上的催化剂被广泛使用，但仍有进一步改进催化剂特性的空间。本文的主题是应用等离子体喷涂在不同几何形状的金属基底（板，泡沫）上沉积氧化铝涂层，用于随后的催化剂合成。喷涂的氧化铝层成功地解决了两个不同的问题：（i）它作为催化剂合成的载体涂层，以及（ii）它保护金属表面免受高温氧化。
Catalysts supported on metals are widely used today, but room still remains for further improvement of catalyst characteristics. The subject of this paper is the application of a plasma spray for the deposition of alumina coatings on metal substrates of different geometry (plates, foams) for subsequent synthesis of catalysts. The alumina layer sprayed successfully solves two different problems: (i) it serves as a washcoat on which a catalyst is synthesized, and (ii) it protects the metal surface from oxidation at high temperatures.
