摘要
为了提高1Cr18Ni9钢基体的耐蚀性和耐磨性,扩大其在工业中的应用范围,采用料浆法在不锈钢基体上制备具有保护性的SiO2基陶瓷涂层。并对涂层进行相结构及显微组织分析,结果表明:涂层与基体结合良好,且涂层中有新相生成。腐蚀试验和磨损试验证明,采用本工艺在1Cr18Ni9钢表面涂覆陶瓷层能大幅度提高基体的耐蚀性和耐磨性,对生产实践有一定的指导意义。
Protective SiO2-based ceramic coatings were prepared on stainless steel by slurry method to improve the corrosion resistance and wear resistance of 1Cr18Ni9. The phase structure and microstructure of the coatings were also investigated. The results show that the bonding of coating and substrate are well-adhered, and the ceramic coatings are found to contain new phases. Corrosion tests and wear tests approve that 1Cr18Ni9 steel coated by this method exhibits excellent corrosion resistance and wear resistance. The coatings have directive significance on the productive practice.
