大家知道我们所熟悉的氧化锆陶瓷具有耐高温、耐腐化侵蚀 、耐磨损及抗热冲击等优点。近年来，随着陶瓷增韧强化技术的进步以及机械加工方法的开发，氧化锆陶瓷的应用范围迅速扩大，那大家知道氧化锆陶瓷加工会遇到哪些主要的问题呢？下面就由专业生产氧化锆陶瓷的厂家科众陶瓷来为大家重点介绍下氧化锆陶瓷加工会遇到的主要问题。

一、氧化锆陶瓷加工的加工方法

氧化锆(gao)陶瓷加(jia)工(gong)(gong)方(fang)法常用分为(wei)两类：机械加(jia)工(gong)(gong)、模(mo)具注(zhu)塑加(jia)工(gong)(gong)等，其中机械加(jia)工(gong)(gong)的(de)方(fang)法效率高，因(yin)而在(zai)工(gong)(gong)业上获得广(guang)泛应用，特别是金刚石砂轮(lun)磨削、研磨和抛光较(jiao)为(wei)普遍。

二(er)、氧化(hua)锆(gao)陶(tao)瓷加工的主要问题

氧化锆陶瓷加(jia)工(gong)(gong)虽(sui)然有许多方法，但(dan)加(jia)工(gong)(gong)成本高(gao)，加(jia)工(gong)(gong)效率低，加(jia)工(gong)(gong)精(jing)度(du)差。其主要(yao)原因(yin)之一是陶瓷的硬度(du)非常高(gao)。对于氧化锆陶瓷未(wei)烧体或焙(bei)烧体主要(yao)用(yong)切削(xue)加(jia)工(gong)(gong)进(jin)(jin)行(xing)粗加(jia)工(gong)(gong)，烧结(把粉(fen)状物(wu)料(liao)转(zhuan)变为致密(mi)体的过程)后(hou)用(yong)磨(mo)削(xue)进(jin)(jin)行(xing)精(jing)加(jia)工(gong)(gong)。
 

氧(yang)化锆(gao)陶瓷螺(luo)丝

根据(ju)氧(yang)化锆(gao)陶(tao)(tao)(tao)瓷情况不(bu)同，也可以(yi)不(bu)经机械加(jia)(jia)工(gong)(gong)(gong)(gong)，直(zhi)接磨削加(jia)(jia)工(gong)(gong)(gong)(gong)烧结体(ti)(ti)(ti)使(shi)之(zhi)达(da)到设计精(jing)(jing)(jing)度（精(jing)(jing)(jing)确度）。就加(jia)(jia)工(gong)(gong)(gong)(gong)过程而(er)言：氧(yang)化锆(gao)陶(tao)(tao)(tao)瓷与(yu)金属(shu)零件几(ji)乎是相似的(de)，但氧(yang)化锆(gao)陶(tao)(tao)(tao)瓷的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余量则(ze)大(da)(da)得多。未烧体(ti)(ti)(ti)或(huo)焙烧体(ti)(ti)(ti)陶(tao)(tao)(tao)瓷粗加(jia)(jia)工(gong)(gong)(gong)(gong)时：易于(yu)(yu)出(chu)现强度不(bu)足或(huo)表(biao)面加(jia)(jia)工(gong)(gong)(gong)(gong)缺陷问题，或(huo)由于(yu)(yu)装卡(ka)不(bu)充分(fen)等(deng)原因，而(er)不(bu)能获得所要求的(de)最(zui)终加(jia)(jia)工(gong)(gong)(gong)(gong)形状。由于(yu)(yu)烧结时不(bu)能保持收缩均匀(yun)，在(zai)粗加(jia)(jia)工(gong)(gong)(gong)(gong)时就要使(shi)尺寸不(bu)要太靠近最(zui)终尺寸，所以(yi)留有的(de)精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)余量就大(da)(da)。对于(yu)(yu)金属(shu)加(jia)(jia)工(gong)(gong)(gong)(gong)，精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)余量如考(kao)虑(lv)热变形和热处(chu)理产(chan)生(sheng)(sheng)(sheng)的(de)黑皮，则(ze)应尽可能留百分(fen)之(zhi)几(ji)毫(hao)米(mi)。对陶(tao)(tao)(tao)瓷加(jia)(jia)工(gong)(gong)(gong)(gong)来说，精(jing)(jing)(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)余量则(ze)需(xu)有几(ji)毫(hao)米(mi)甚至十(shi)几(ji)毫(hao)米(mi)。加(jia)(jia)工(gong)(gong)(gong)(gong)余量大(da)(da)，生(sheng)(sheng)(sheng)产(chan)率降(jiang)低(di)，生(sheng)(sheng)(sheng)产(chan)成本升高。

氧化(hua)锆陶瓷(ci)加工(gong)(gong)的(de)另一个(ge)问题是(shi)加工(gong)(gong)刀(dao)(dao)(dao)具费用(yong)(yong)大，切(qie)削加工(gong)(gong)需使(shi)用(yong)(yong)高(gao)价的(de)烧结(把粉状物料转变为致密(mi)体(ti)的(de)过程)金刚石、CBN刀(dao)(dao)(dao)具，精加工(gong)(gong)也是(shi)以(yi)金刚石砂轮为主，因此刀(dao)(dao)(dao)具费用(yong)(yong)要高(gao)出(chu)金属切(qie)削所用(yong)(yong)刀(dao)(dao)(dao)具数十(shi)倍至百倍。氧化(hua)锆陶瓷(ci)的(de)强度对于(yu)(yu)加工(gong)(gong)条件是(shi)敏感(感觉敏锐)的(de)，难于(yu)(yu)实现高(gao)效率(lv)加工(gong)(gong)所以(yi)氧化(hua)锆陶瓷(ci)的(de)加工(gong)(gong)成(cheng)本相对于(yu)(yu)普(pu)通材料要高(gao)出(chu)许多的(de)。
