前言工业的发展需要具有极高硬度和高耐磨、高耐热、高耐蚀的,被称作纯陶瓷或高级陶瓷的新颖特殊陶瓷。当把这类陶瓷用于机械结构中时,必须进行精加工以获得精确的尺寸,因为未烧结的成形材料在烧结过程中会收缩约20%的长度。金刚石砂轮磨削经常被用于它们的精加工,但砂轮的严重损耗导致精加工的费用增大。一些复杂零件还不能用它来成形。由于陶瓷的导电性差,难以应用通常用于加工难切削材料的电加工工艺,可是有人研究了自粘结的 REFEL SiC 的电火花加
Preface The development of industry requires novel special ceramics called pure or advanced ceramics with extremely high hardness and high wear resistance, high heat resistance and high corrosion resistance. When this type of ceramic is used in a mechanical structure, it has to be finished to obtain the exact size because unsintered forming materials shrink about 20% in length during sintering. Diamond wheel grinding is often used for their finishing, but serious wear and tear of the grinding wheel results in increased finishing costs. Some complex parts can not use it to shape. Due to the poor conductivity of ceramics, it is difficult to apply the electroforming processes that are commonly used to machine difficult-to-cut materials. However, studies have been made on the EDM of self-bonded REFEL SiC
