摘要针对传统SHS法制备陶瓷内衬小口径管中陶瓷熔涂长度过短的问题，开发了制备复合细长管的新工艺。以Al粉和Fe2O3粉为反应原料，混合均匀后配合钢棒装填粉末，使粉料中形成空腔，反应时不锈钢管与地面呈80°夹角。结果表明：新工艺能够解决反应产物堵塞管道和管壁烧穿的问题，显著提高体系的燃烧速度，增加陶瓷的熔涂长度。钢管内壁均已涂上陶瓷，涂层厚度为1. 2～1. 5 mm。涂层中气孔少，不存在凝固缺陷，可防止腐蚀性液体对基体的侵蚀。

Abstract：A novel technique concerned composite pipe was proposed to solve the problem that the coating length of ceramic was too short by traditional SHS method. Raw materials contained Al powders and Fe2O3 powders were blended uniformly and filled into stainless steel tube combined with a steel bar so that a cavity could form in the reaction mass. The angle between the pipe and the ground was 80°. Experimental results showed that the new technique could solve the problem about pipe plugged and burned by reaction product and the coating length was increased as a result of the improvement of the combustion speed of reactants. The inner wall of the steel tube are coated with ceramic which had the thickness of 1.2～1.5 mm coating. The coating had few pores without through-holes which could prevent the matrix from eroding by corrosive liquid.

Key words： SHS self-gravitation ceramic slender pipe cavity combustion speed
