Continuous ceramic composite plating method and apparatus for long doctor base materials

A continuous ceramic composite plating method for long doctor base materials comprising:

• a degreasing step;
• rinsing step;
• acid immersion step;
• rinsing step;
• electroless ceramic composite nickel plating step;
• plating solution collection step;
• rinsing step;
• and drying step between a first step of supplying continuously a plurality of long doctor blade base materials held on a plurality of material reels-spirally while the blade surfaces are maintained in a horizontal direction with respect to the surface of a solution and a predetermined interval therebetween is maintained and a final step of taking up continuously the plurality of doctor blade base materials on a plurality of corresponding take-up reels while the plurality of blade base materials are cramped by a plurality of pinch rolls.
