本文介绍了一项关于陶瓷材料应用于汽车零部件时的质量保证和成本考虑的研究结果。对氮化硅的磨削特性及磨削表面缺陷与材料强度的关系进行了实验分析。研究发现，选择合适的研磨条件，可以在保证良好质量的同时，以与金属单位宽度的去除率相当的效率研磨陶瓷。

THIS PAPER PRESENTS THE RESULTS OF A STUDY CONCERNING QUALITY ASSURANCE AND COST CONSIDERATIONS WHEN CERAMIC MATERIALS ARE APPLIED TO AUTOMOTIVE PARTS. EXPERIMENTAL ANALYSES WERE MADE OF THE GRINDING CHARACTERISTICS OF SILICON NITRIDE AND THE RELATIONSHIP BETWEEN POSTING-GRINDING SURFACE DEFECTS AND MATERIAL STRENGTH. IT WAS FOUND THAT A SUITABLE SELECTION OF GRINDING CONDITIONS HOLDS OUT THE POSSIBILITY OF GRINDING CERAMICS WITH HIGH EFFICIENCY COMPARABLE TO THE REMOVAL RATE PER UNIT WIDTH ACHIEVED FOR METALS WHILE AT THE SAME TIME ASSURING GOOD QUALITY.
