CrO_3、CuO对SHS陶瓷衬层复合钢管组织和性能的影响

The Effect of Additives on the Structure and Property of SHS Ceramic Lined Composite Pipes

采用SHS铝热-重力分离法制备了陶瓷贻复合钢管。在SiO_2、NaF质量分数均为4％的条件下,研究了CuO、CrO3等添加剂对陶瓷内衬致密度、组织和性能的影响.并对二者的影响进行了比较。结果表明,在锅热剂为AL+Fe_2O_3+4％SiO_2+4％NaF+4％CrO_3的条件下,陶瓷衬层复合钢管具有较好的结合强度和耐腐蚀性能。

The ceramic lined composite pipes were produced by gravitational separation SHS method.with the condition of adding 4% SiO2 and 4% NaF as contant,the effect of different amount of CuO and CrO3 on densification, structure and property of the ceramic layer was studied. It was shown that belter comprehensive properties were achieved in ceramic lined composite pipes with the compositions of Al+Fe2O3+4%SiO2+4%NaF+4%CrO3.
