一、氧化锆陶瓷加工的加工方法

氧化(hua)锆陶瓷(ci)加(jia)工方法常(chang)用分为(wei)两(liang)类：机(ji)械加(jia)工、模(mo)具(ju)注(zhu)塑加(jia)工等，其中机(ji)械加(jia)工的(de)方法效(xiao)率(lv)高(gao)，因而在工业(ye)上获得广泛应用，特(te)别是金刚石(shi)砂轮磨(mo)削(xue)、研磨(mo)和抛光较(jiao)为(wei)普遍。

二、氧化锆陶瓷加(jia)工(gong)的(de)主要(yao)问题

氧(yang)化锆陶瓷加(jia)(jia)工(gong)(gong)虽(sui)然有许多方法，但加(jia)(jia)工(gong)(gong)成本高(gao)，加(jia)(jia)工(gong)(gong)效率低，加(jia)(jia)工(gong)(gong)精度差(cha)。其主要原因之一是陶瓷的(de)硬(ying)度非常(chang)高(gao)。对(dui)于(yu)氧(yang)化锆陶瓷未(wei)烧体(ti)或焙烧体(ti)主要用(yong)切削加(jia)(jia)工(gong)(gong)进行粗加(jia)(jia)工(gong)(gong)，烧结(把粉状物料(liao)转变(bian)为致密体(ti)的(de)过(guo)程)后用(yong)磨削进行精加(jia)(jia)工(gong)(gong)。

根(gen)据氧(yang)(yang)化锆陶瓷(ci)情(qing)况(kuang)不(bu)同，也可以不(bu)经机械(xie)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，直接磨削加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)烧结体(ti)使(shi)之达到设计(ji)精(jing)(jing)度（精(jing)(jing)确度）。就(jiu)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)过程而言：氧(yang)(yang)化锆陶瓷(ci)与(yu)金属(shu)零件(jian)几乎(hu)是相似的(de)(de)，但氧(yang)(yang)化锆陶瓷(ci)的(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)则大得多。未烧体(ti)或焙烧体(ti)陶瓷(ci)粗(cu)(cu)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)时：易(yi)于出(chu)现强度不(bu)足或表面加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)缺陷问题(ti)，或由于装卡不(bu)充分等(deng)原因(yin)，而不(bu)能获(huo)得所要求(qiu)的(de)(de)最终(zhong)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)形状。由于烧结时不(bu)能保持(chi)收缩均匀，在(zai)粗(cu)(cu)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)时就(jiu)要使(shi)尺寸(cun)不(bu)要太靠近最终(zhong)尺寸(cun)，所以留有(you)的(de)(de)精(jing)(jing)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)余量(liang)(liang)就(jiu)大。对于金属(shu)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，精(jing)(jing)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)如(ru)考虑热变形和热处理产(chan)(chan)生(sheng)的(de)(de)黑皮，则应尽可能留百分之几毫米。对陶瓷(ci)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)来说，精(jing)(jing)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)则需有(you)几毫米甚(shen)至十几毫米。加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)大，生(sheng)产(chan)(chan)率降低，生(sheng)产(chan)(chan)成本升高。

氧化锆陶瓷加(jia)工(gong)的(de)另一个(ge)问题是加(jia)工(gong)刀具(ju)费用(yong)(yong)大(da)，切削加(jia)工(gong)需使用(yong)(yong)高(gao)价的(de)烧结(把(ba)粉(fen)状物料转变为致密体的(de)过程(cheng))金(jin)(jin)刚石(shi)、CBN刀具(ju)，精(jing)加(jia)工(gong)也是以金(jin)(jin)刚石(shi)砂(sha)轮为主，因(yin)此刀具(ju)费用(yong)(yong)要高(gao)出金(jin)(jin)属切削所(suo)用(yong)(yong)刀具(ju)数(shu)十倍(bei)至百倍(bei)。氧化锆陶瓷的(de)强度对于(yu)加(jia)工(gong)条件是敏(min)感(感觉敏(min)锐)的(de)，难于(yu)实(shi)现高(gao)效(xiao)率加(jia)工(gong)所(suo)以氧化锆陶瓷的(de)加(jia)工(gong)成本相对于(yu)普通材料要高(gao)出许多的(de)。
