    • Gaskets are placed in joints between adjacent nonferrous metal engine members of a water-cooled engine for an outboard motor, such as a cylinder block, a cylinder head, a crankcase, a mount case and an oil pan, to seal the joints. Each of the gaskets has a base member formed of a stainless steel. The surfaces of the base member are coated with electrochemical corrosion preventing films formed by applying a liquid containing flakes of an aluminum alloy or a zinc alloy and a silicate resin in films and baking the films of the liquid. The electrochemical corrosion preventing films are coated with sealing films formed by applying a liquid containing aluminum flakes and a silicate resin to the electrochemical corrosion preventing films and baking the films of the liquid. The gaskets are prevented from electrochemically corroding despite potential difference between each gasket and the adjacent engine members.
    • 垫圈被放置在用于舷外马达(例如气缸体,气缸盖,曲轴箱,安装壳体和油盘)的水冷发动机的相邻有色金属发动机构件之间的接头中以密封接头。 每个垫片具有由不锈钢形成的基部构件。 基材的表面涂覆有通过将包含铝合金或锌合金薄片和硅酸盐树脂的液体涂覆在膜中并烘烤液体膜而形成的电化学防腐蚀膜。 电化学腐蚀防止膜涂覆有通过将包含铝片和硅酸盐树脂的液体施加到电化学腐蚀防止膜并烘烤液体膜而形成的密封膜。 即使每个垫圈和相邻的发动机构件之间存在潜在差异,垫圈也不会被电化学腐蚀。
