Abstract

PURPOSE: To provide both corrosion-resistance and errosion-resistance to a blade with the cost and the work efficiency thereof comparing with that of the conventional ones, by applying a fluoroplastic material layer on the leading edge portion of a blade and an acid-resisting and corrosion-resisting resin material layer on the remaining portion of the blade.
CONSTITUTION: A fluoroplastic paint (vinylidene fluoride, Teflon-S or the like) is coated on the surface of the leading edge portion of a blade 11 made of generally used blade materials, such as, for example, SS41 material, so that a fluoroplastic material layer 12 is formed, and an acid-resisting and corrosion- resisting resin paint (flake containing paint such as, for example, saturated polyester, vinylester resin or the like) so that an acid-resisting and corrosion resisting material layer 13 is formed. Thus, the provision of such a fluoroplastic material layer to the leading edge of the blade allows both corrosion-resistance and errosion-resistance to be ensured therefor, and the provision of the acid- resisting and corrosion resisting material layer to the remaining portion of the blade allows metal materials of low costs to be used as the blade materials.
