1252149 V. INSTRUCTION DESCRIPTION α) TECHNICAL FIELD The present invention relates to a method for manufacturing a wet-plated hard layer of a serrated cutting end, in particular to a method in which a tantalum carbide particle is mixed in a plating solution, and heat treatment is performed after wet plating is completed. A method of forming a wear-resistant reinforcing bond layer on the surface of the sawtooth cutting end. [Prior Art] According to the method of improving the hardness of the serrated cutting end surface, one of the methods used in the industry is to electroplat a saw metal on the saw blade with a metal plating layer containing industrial diamond particles (for example, nickel metal). For example, in the new patent case of "Silicon monument band saw blade improved structure" in the 8 8 2 1 6 6 1 4, it is mainly provided with a plurality of arc-shaped notches at equal intervals on the blade of the band saw, and the blade portion is Grinding into a circular arc-shaped section, and then plating a metal coating containing industrial diamond particles on the outer edge of the blade to grind the quartz brick from high-hardness industrial diamonds, and to make the grinding The chips can be discharged from the gap to enhance the cutting effect. In the above-mentioned No. 8 8 2 1 6 6 1 4 "modified structure of saw blade for quartz brick band saw", the band saw is flat to reduce the gap formed by the saw blade, and therefore, is applied by electroplating. Plating can produce a uniform coating. However, the sawtooth of the saw blade for sawing metal is usually in the form of left and right staggered, that is, the sawtooth portion of the saw blade is not planar and has a complex multi-faceted state. The electroplating method is difficult to produce a uniform thickness coating on the sawtooth portion; and the conditions required for electroplating are complicated, and the P Η value and current density of the plating solution are important conditions for affecting the adhesion of the coating, once these conditions are improperly controlled Will produce a poor adhesion coating, the thickness of the coating
