在这项研究中，高效，高精度磨削硬质合金使用特定的砂轮进行，并详细研究了磨削表面特性。结果表明，使用铬结合剂砂轮的最终精加工产生了非常光滑的表面，平均粗糙度Ra为4 nm。研磨过程产生了富含铬和铜的表面层，以及大量的氧扩散。使用显微划痕法的粘合强度测试也进行了地面基板上涂有类金刚石碳（DLC）膜。由于其与DLC膜的强化学亲和力，由铬结合的轮研磨的表面表现出上级粘合强度。
In this study, efficient, high-precision grinding of cemented carbide alloys using a specific grinding wheel was performed, and the ground surface characteristics were investigated in detail. The results showed that final finishing using a chromium-bonded wheel produced an extremely smooth surface with an average roughnessRaof 4 nm. The grinding process produced a chromium- and copper-rich surface layer, as well as a large amount of diffusion of oxygen. Adhesive strength tests using a microscratching method were also carried out on ground substrates coated with diamond-like carbon (DLC) films. The surface ground by the chromium-bonded wheel exhibited superior adhesive strength due to its strong chemical affinity with the DLC film.
