Title:
METAL PART, AND SURFACE TREATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2001/056719
Kind Code:
A1
Abstract:
A metal part having rubber bonded thereto over part or all of its surface thereof; and a method of treating the surface of this metal part, comprising the steps of improving adhesion between the metal and the rubber, facilitating formation of a surface roughness in a particular portion of the metal part, forming a surface roughness (1c) intended to increase adhesion between the metal and the rubber in that region (1b) of the surface (1a) of the metal part (1) in which the rubber (3) is to be bonded for the purpose of improved processing accuracy for surface roughness, improved maintenance of the mold, reduction of processing cost and reduction of the number of man-hours, and forming a surface roughness in advance in a mold for processing the metal part, whereby the surface roughness (1c) is transferred from the mold to the metal part during processing. The size of the surface roughness is preferably 10 $g(n)m or above but less than 60 $g(n)m.
