20130291445 | DIAMOND ABRASIVE GRAIN AND ELECTROPLATED TOOL HAVING THE SAME - A coating method on diamond abrasive grains is used to form a conductive film on diamond abrasive grains. The conductive film has chemical composition gradient giving the diamond abrasive grain an outwardly increasing electrical conductibility as a function of film thickness. The subsequent electroplating layer can therefore more effectively embed the modified diamond abrasive grains, whilst the adhesion/bonding strength between substrate (work piece for electroplating) and the diamond abrasive grains is improved. | 11-07-2013 |
