技术领域
本发明涉及陶瓷材料领域，尤其涉及喷嘴用高耐磨Si3N4基金刚石复合陶瓷材料和该材料的制备方法。
背景技术
喷嘴广泛应用于工业领域，是表面清洗、强化和喷射切割等设备的关键部件之一，属于易磨耗部件。目前，国内外常用的喷嘴材料主要为金属、硬质合金等，此类材料的硬度低、耐磨性差，导致喷嘴使用寿命短，频繁更换不仅增加成本，降低生产率，而且增大了工人的劳动强度。陶瓷材料因具有硬度高、耐磨损等优点，是喷嘴的理想材料之一，陶瓷喷嘴一直是我国喷嘴技术研发的重点。金刚石因具有极高的硬度，是制造喷嘴的理想材料，陶瓷基的金刚石复合材料可进一步改善陶瓷材料的硬度，增加材料的耐磨性，但金刚石复合材料烧结困难，高温下易发生氧化与石墨化，是材料制备的一大技术难题。为降低或避免金刚石的氧化与石墨化，通常采用放电等离子烧结、高温高压烧结、化学气相沉积的方法制备材料，对设备要求高，制备成本高且工艺复杂，不易控制。例如，Huang等采用放电等离子烧结方法制备Si3N4基的金刚石陶瓷材料，整个实验过程中脉冲电流的脉宽为10ms，间隔时间为5ms，最大压力达到 100MPa，升温速率为200℃/min，对减小或避免金刚石的石墨化起到了显著作用(Shuigen Huang,Akhilesh Kumar Swarnakar,Kim Vanmeensel,Jef Vleugels.Diamond dispersed Si3N4 composites obtained by pulsed electric currentsintering. Journal of the European Ceramic Society,2013,33(6):1237–1247)。
