An electrolyte containing carbon microspheres (CMSs) was prepared for electrolytic dressing of a multi‐layer brazed coarse‐grained diamond wheel. And the influence of CMSs on the electrolytic in‐process dressing grinding performance of Si3N4 ceramics with the brazed wheel was investigated. The results indicate that the CMSs can increase the electrolytic capacity of the electrolyte, which increases the thickness of the oxide film formed on the brazed wheel surface, and the worn diamond grit can easily fall off from the bonding matrix. In addition, the CMSs were adsorbed and distributed on the film, which effectively improves its densification and adhesion strength. This thicker and denser oxide film can improve the polishing effect of the brazed wheel. Thus, a better machined surface quality and less subsurface damage of the Si3N4 ceramics can be obtained by the multi‐layer brazed coarse‐grained diamond wheel with electrolyte containing CMSs.

含碳微球的电解质对多层钎焊粗粒金刚石砂轮的电解加工修整性能
制备了含碳微球(CMSs)的电解质,用于多层铜焊粗晶粒金刚石砂轮的电解修整。CMS对Si 3 N 4电解修整磨削性能的影响研究了带钎焊轮的陶瓷。结果表明,CMSs可以增加电解质的电解容量,从而增加在钎焊轮表面上形成的氧化膜的厚度,并且磨损的金刚石砂粒可以容易地从粘结基体上脱落。另外,CMS被吸附并分布在膜上,这有效地提高了其致密性和粘合强度。这种较厚且致密的氧化膜可以改善钎焊轮的抛光效果。因此,采用含CMS电解质的多层钎焊粗晶金刚石砂轮可以获得更好的机加工表面质量,并减少Si 3 N 4陶瓷的次表面损伤。
