Title (EN) NICKEL COATED DIAMOND PARTICLES AND METHOD OF MAKING SAID PARTICLES
(FR) PARTICULES DE DIAMANT REVÊTUES DE NICKEL ET PROCÉDÉS DE FABRICATIONS DESDITES PARTICULES
Abstract: front page image
(EN)A method of evenly coating small abrasive particles, specifically a method of coating diamond particles ?10 µm with nickel, and an abrasive article containing the coated abrasive particles, for example, a fixed diamond wire. The method includes applying ultrasonic energy to the plating bath and adjusting the power of the ultrasonic energy that a non-agglomeration factor (NAF) of the batch of abrasive particle is at least about 0.9, the non-agglomeration factor defined as a ratio (D50sa/D50b), wherein D50b represents the median particle size of the coated abrasive particles and D50sa represents the median particle size of the abrasive particles prior to coating.
(FR)L'invention concerne un procédé de revêtement de façon régulière de petites particules abrasives, en particulier un procédé de revêtement de particules de diamant de 10 µm avec du nickel, et un article abrasif contenant les particules abrasives revêtues, par exemple, un fil diamanté fixe. Le procédé comprend l'application d'une énergie ultrasonore dans le bain de placage et le réglage de la puissance de l'énergie ultrasonore de telle sorte qu'un facteur de non-agglomération (NAF) du lot de particules abrasives est au moins environ 0,9, le facteur de non-agglomération étant défini comme le rapport (D50sa/D50b), où D50b représente la dimension de particule médiane des particules abrasives avant le revêtement.
