金刚石砂轮的性能可以通过优化磨粒和粘结材料来提高。因此，金刚石磨粒通常被镀镍，用于树脂粘结。最近开发的一种涂层工艺可显著增加金属沉积物的表面积，因此，当用于树脂结合剂砂轮时，与市场上的大多数产品相比，仅在稍高的研磨力下，涂层砂砾将显示出更高的G比。采用该技术和标准技术对四种不同易碎等级的金刚石进行了镀镍，将其嵌入树脂中制备砂轮，并在碳化钨工件的磨削中进行了对比测试，以证明新涂层的优越性。

THE PERFORMANCE OF A DIAMOND WHEEL CAN BE IMPROVED BY OPTIMIZING ABRASIVE GRITS AS WELL AS THE BOND MATERIAL. THUS DIAMOND GRITS ARE OFTEN NICKEL-COATED FOR RESIN BOND USES. A RECENTLY DEVELOPED COATING PROCESS ALLOWS A SIGNIFICANTLY INCREASED SURFACE AREA OF THE METALLIC DEPOSIT, SO THE COATED GRITS, WHEN USED IN A RESIN BOND WHEEL, WILL EXHIBIT A HIGHER G-RATION THAN MOST OF THE PRODUCTS ON THE MARKET AT ONLY A LITTLE HIGHER GRINDING FORCE. FOUR GRADES OF DIAMOND OF DIFFERENT FRIABILITY LEVELS WERE NICKEL-COATED BY BOTH THIS AND STANDARD TECHNIQUE, EMBEDDED IN RESIN TO PREPARE WHEELS, AND COMPARATIVELY TESTED IN A GRINDING OF TUNGSTEN CARBIDE WORK TO DEMONSTRATE THE SUPERIORITY OF THE NEW COATING.
