Conditioning assembly and dressing device thereof

Abstract

A conditioning assembly and a dressing device thereof are provided. The dressing device includes a metallic porous structural body, a plurality of abrasive particles, and a brazing filler metal. The plurality of abrasive particles are dispersed and embedded onto the metallic porous structural body, and each of the abrasive particles is partially exposed on the metallic porous structural body. The brazing filler metal fills and penetrates into the metallic porous structural body, and the brazing filler metal bonds with the metallic porous structural body and the plurality of abrasive particles. The materials that constitute the metallic porous structural body and the brazing filler metal have at least one common constituent element.

What is claimed is: 
     
         1 . A dressing device, comprising:
 a metallic porous structural body;   a plurality of abrasive particles dispersed and embedded onto the metallic porous structural body, wherein each of the abrasive particles is partially exposed on the metallic porous structural body; and   a brazing filler metal that fills and penetrates into the metallic porous structural body and that bonds with the metallic porous structural body and the plurality of abrasive particles;   wherein materials that constitute the metallic porous structural body and the brazing filler metal have at least one common constituent element.   
     
     
         2 . The dressing device according to  claim 1 , wherein intermetallic compounds are formed between the brazing filler metal and the metallic porous structural body, and between the brazing filler metal and the plurality of abrasive particles. 
     
     
         3 . The dressing device according to  claim 1 , wherein the materials that constitute the metallic porous structural body include nickel, iron, copper, nickel alloy, iron alloy, copper alloy, titanium alloy, foamed nickel, foamed titanium, or foamed stainless steel. 
     
     
         4 . The dressing device according to  claim 1 , wherein the metallic porous structural body is a compressed structure with a porosity of less than 50%. 
     
     
         5 . The dressing device according to  claim 1 , wherein a melting point of the metallic porous structural body is at least 100° C. higher than a melting point of the brazing filler metal. 
     
     
         6 . The dressing device according to  claim 1 , wherein the flatness of the metallic porous structural body is less than 50 μm. 
     
     
         7 . A conditioning assembly, comprising:
 a base body; and   the dressing device according to  claim 1 , wherein the dressing device is disposed on the base body.   
     
     
         8 . The conditioning assembly according to  claim 7 , wherein materials that constitute the base body include stainless steel, metal alloy, ceramic material, or engineering plastic. 
     
     
         9 . The conditioning assembly according to  claim 7 , further comprising an adhesive disposed between the base body and the dressing device, wherein the adhesive is used to bond the base body and the dressing device. 
     
     
         10 . The conditioning assembly according to  claim 9 , wherein the adhesive is another brazing filler metal or polymer adhesive.
