| 摘 要： | 陶瓷涂层材料以其高硬度、耐腐蚀、耐高温、抗氧化等一系列优点,在航空航天、武器装备、核工业、石油化工等领域具有广阔的应用前景.SiC/Al_2O_3复相陶瓷在常温和高温下都具有较好耐磨性和化学稳定性,是一种极具工程应用前景的复合陶瓷材料.本研究采用优质陶瓷先驱体聚合物PCS,添加惰性填料SiC纳米颗粒和活性填料金属Al粉共同作用,克服了先驱体法制备陶瓷材料中存在较大体积收缩的缺点,在金属基体上制备了单层厚度可达50 μm的致密SiC/Al_2O_3复相陶瓷涂层,复相陶瓷涂层中的SiC来自于先驱体PCS热解转化的SiC和添加的纳米SiC颗粒;其中的Al_2O_3来自于金属Al粉的氧化.该化学反应方法在金属基体上成功地制备出连续、致密的SiC/Al_2O_3复相陶瓷涂层,既简单又方便,表现出极大的应用潜力. |

| Abstract: | Ceramic coatings on metallic substrates have increasing application in industry due to enhanced mechanical properties and corrosion resistance of the ceramic coatings.In particular,the SiC/Al2O3 composite coating is desirable since it could offer both high wear resistance and chemical stability at both room and high temperature.In this work,polycarbosilane(PCS) as the SiC precursor polymer,SiC nano powder as the inert filler,Al powder as the reactive filler were mixed to produce the SiC/Al2O3 composite coat... |
| Keywords: | polymer derived silicon carbide alumina ceramic composites coatings |
