JOINT LAYER PROTECTION STRUCTURE FOR WEAR RESISTING PART

摘要

PROBLEM TO BE SOLVED: To provide a protection structure of joint layers which allows sufficiently practical use replacing the existing brazed joints by improving the resistance to water and chemicals at parts with adhesives exposed of the joint layers concerning wear resisting parts of blade tools or the like in which wear resisting members such as edge parts are joined on body parts such as bed metals with the adhesives. SOLUTION: In the wear resisting part 28 of a blade tool or the like in which the wear resisting member 24 such as the edge part is joined on the body part 26 such as the bed metal with the adhesive 30, a required portion of the part with an adhesive layer exposed at a joint area between the wear resisting member 24 and the body part 26 is covered with a filler 40 or a cover material 42. In the wear resisting part of the blade tool or the like, the required portion of the part with the adhesive layer exposed at the joint area between the wear resisting member 24 and the body part 26 is covered with a sticking member 46.
