Abstract
PURPOSE: To decrease the current transmission resistance with increasing the adhesive property and to prolong a life of roll, by covering plating layer of nickel, copper and chromium in order on the surface of roll main body made of iron.
CONSTITUTION: The nickel plating layer 17 having the thickness of about 0.05W 0.10mm, is formed on the outer surface of the roll main body 6 made of iron and copper plating layer having the thickness of about 3W5mm, is formed on its outer circumference and moreover, the hard chromium plating layer 19 having the thickness of about 0.15W0.25mm, is formed on its outer circumference. Or, the outermost chromium plating layer is formed by the double plating layer of the first layer 19' having the thickness of 0.10W0.15mm and the second layer 19" having the thickness of 0.10W0.15mm. Hereby, adhesive property between plating layers is made good and heat generation by current transmission resistance as the whole plating layer is decreased and also, blister and exfoliation of the plating layer is prevented. Also, the current transmitting property and productivity etc. can be assured with a low cost by increasing the thickness of the cheap copper plating layer.
