【摘要】 本文研究了添加剂对钢基陶瓷衬复合管的显微组织和性能的影响。研究结果表明:具有发送的 Al₂O₃树枝状粗晶以及气孔率低的陶瓷层的复合管,其韧性好,耐磨、耐蚀性强。细化 Al₂O₃枝晶并不能明显降低陶瓷层的气孔率,改善复合管的性能。更多还原

【Abstract】 Tests were conducted to study the additive’s influence on the structures and properties of steel-matrix ceramic-lining composite pipes.It is shown that the composite pipe in whose ceramic layer there are coarse Al₂O₃ branch grains and low porosity has better toughness,wearability and corrosion resistance.On the other hand,fining Al₂O₃ branch grains can’t obviously reduce the porosity and improve the properties of composite pipe.更多还原
