  • Publication number: 20050281956
    Abstract: A thermal spraying method is provided for manufacturing anti-sliding plates. The method uses a mask located upon a plate with a specific height. The mask has plural openings of a specific shape. When a thermal spraying device thermal-sprays thread material from the upper side of the mask, melted thread material passes through the openings to form anti-sliding spots of a specific shape on the plate. By means of thermal spraying on the mask with the openings, an anti-sliding plate with high roughness is efficiently produced.
