由活性磨粒组成的珩磨轮表面微观形貌是影响珩磨特性的关键因素，对其控制是实现高效精密珩磨的充分条件。基于磁控溅射法和相场法，建立了珩磨轮表面立方氮化硼（CBN）涂层形成的理论模型。采用有限差分法求解物理气相沉积（PVD）离散相场方程。编写MATLAB程序模拟珩磨轮表面CBN涂层的形成过程和微观形貌。田口方法旨在研究溅射时间、基板温度、气体流量和反应空间与活性磨料的数量以及磨料的长度、宽度、高度和尺寸的关系。仿真结果与扫描电镜（SEM）检查高度相似，表明该模型能够准确有效地模拟不同工艺条件下砂轮表面磨料形貌，为珩磨轮表面CBN磨损形貌的预测和控制提供理论依据。
The microtopography of a honing wheel surface composed of active abrasive grains is the key factor affecting the honing characteristics, and control of it is a sufficient condition to realize high-efficiency precision honing. Based on the magnetron sputtering method and phase field method, a theoretical model of cubic boron nitride (CBN) coating formation on a honing wheel surface is established. The physical vapor deposition (PVD) discrete phase field equation is solved by the finite difference method. A MATLAB program is compiled to simulate the formation process and micromorphology of the CBN coating on the honing wheel surface. A Taguchi method is designed to study the relationships of the sputtering time, substrate temperature, gas flow rate, and reaction space with the number of active abrasives and the length, width, height, and size of the abrasives. The simulation results are highly similar to the scanning electron microscopy (SEM) examinations, which shows that the model can accurately and effectively simulate the abrasive morphology of the wheel surface under different process conditions and provide a theoretical basis for the prediction and control of the CBN wear morphology on a honing wheel surface.
