Description

超声波分散碳化铪碳化硼-碳纤维摩擦材料的制备方法
技术领域
本发明涉及一种碳纤维和陶瓷材料复合的摩擦材料的制备方法，属于复合材料制备技术领域。
背景技术
摩擦材料目前主要采用的是碳纤维和碳（C/C）复合材料，由于C/C复合材料的耐磨性能相对较低，人们正在寻求耐磨性能更高的摩擦材料的制备方法。另外，C/C复合材料在潮湿的环境中，它的摩擦性能会降低，给使用带来严重的安全隐患。
发明内容
本发明的目的在于提供一种能克服上述缺陷、实现制备更高强度、更高摩擦性能及适应各种气候条件的摩擦材料的制备方法。其技术方案为：
超声波分散碳化铪碳化硼-碳纤维摩擦材料的制备方法是将密度为0.1~1.8 g/cm3石墨化的碳纤维毯进行渗碳处理后进行沉积碳化硼处理，再进行超声波分散碳化铪填充处理，再进行埋入渗硅处理，然后在氮气气氛中氮化处理制得超声波分散碳化铪碳化硼-碳纤维摩擦材料，具体步骤如下：
（1）将密度为0.1~1.8g/cm3石墨化的碳纤维毯在900~1100℃温度下通入丙烷气和氮气的混合气体，丙烷气:氮气的摩尔比为1:4~6，流量控制在50~600ml/min，渗碳处理10~24小时获得渗碳碳纤维毯；
（2）将上述渗碳碳纤维毯在900~1100℃温度下通入三氯化硼、甲烷、氢气和氩气的混合气体，三氯化硼:甲烷:氢气:氩气的摩尔比为1:1~2:3~6:4~6，流量控制在50~600ml/min，沉积碳化硼处理10~24小时获得沉积碳化硼碳纤维毯；
（3）将上述沉积碳化硼碳纤维毯浸入粒度小于0.3μm含量为5~20%碳化铪的浆料里，置于超声波清洗器中填充碳化铪处理30~50分钟，取出干燥后制得填充碳化铪碳纤维毯，其中，浆料为含聚丙烯酸铵0.5~1.5%pH值为9~11的水溶液；
（4）将上述填充碳化铪碳纤维毯埋入渗硅料里，在真空气氛下1500~1800℃的温度下渗硅处理3~5小时制得渗硅碳纤维毯，其中，渗硅料为硅粉30~50%和直径为0.5~3mm炭粒50~70%的混合物外加5~15%浓度为0.2~0.6%的聚乙烯醇水溶液均匀混合干燥后制得；
（5）将上述渗硅碳纤维毯在1350~1700℃的温度下氮化处理10~24小时制得超声波分散碳化铪碳化硼-碳纤维摩擦材料。
本发明与现有技术相比，其优点为：
1、本发明使用的碳纤维毯是石墨化的碳纤维毯，或石墨化的针刺碳纤维毯，或石墨化的编织碳纤维布，或石墨化的三维编织碳纤维织块；
2、本发明制备的摩擦材料是由碳纤维和碳化铪、氮化硅复合的一种高强度、高摩擦性能、适应各种气候条件下的摩擦材料；
3、通过渗碳、沉积碳化硼、填充碳化铪、埋入渗硅及氮化等步骤实现摩擦材料的制备，渗碳和沉积碳化硼两个步骤是为了保护碳纤维表面不受破坏而在碳纤维表面赋予的炭涂层和碳化硼涂层，因为在渗硅的过程中碳化硼涂层会阻挡硅蒸汽渗入，碳化硼涂层一旦渗漏，渗碳涂层与硅蒸汽反应生成碳化硅进一步阻挡硅蒸汽，从而保护碳纤维表面不受破坏；
4、碳纤维毯具有很高的气孔率，单靠渗碳和沉积碳化硼会需要很长时间才能达到致密化，制造成本很高。采用填充碳化铪和埋入渗硅的方法填充碳纤维毯的空隙就会非常方便，省时省力，同时填充碳化铪能够进一步提高摩擦材料的耐磨性能；
5、本发明利用超声波声的作用在浆料中产生微泡，当声压或者声强达到一定程度时，微泡就会迅速膨胀，然后又突然闭合，微泡闭合的瞬间产生冲击波，使微泡周围产生约1012pa的压力，将碳化铪颗粒强制填充到沉积碳化硅碳纤维毯的空隙中，达到填隙的目的；
6、采用浆料分散碳化铪填充处理，可以有效提高碳化铪颗粒悬浮性能，提高填充效率，在氮化过程中生成的氮化硅将碳化铪颗粒牢固地结合在一起；
7、由于渗入的金属硅熔点较低为1420℃左右，摩擦材料工作面的温度瞬时可达近2000℃，将金属硅氮化生成氮化硅，形成微孔结构的摩擦材料，可以大幅度提高摩擦材料工作面的耐受温度，提高摩擦材料的使用寿命。
