摘　　要：本文以铝粉及六方氮化硼为原材料,添加粘结剂,采用固相混合的方法制备了复合型铝基氮化硼封严涂层材料;采用等离子喷涂方法制备了封严涂层,并对喷涂后涂层的微观结构、硬度、结合强度和抗热震性等进行了研究。试验表明,该种涂层材料粉末具有良好的物理、化学性能,且喷涂后的涂层各项性能良好,可作为一种新型的封严涂层材料加以应用。In this paper, Aluminum-based boron nitrid composite which composed of Aluminum powder and boron nitrid as raw material, adding binder was prepared using solid phase blending method. Seal coating was prepared by plasma spraying. The hardness, bonding strength, thermal shock resistance and micro-structure of coating were researched. Tests showed that this kind of powder has outstanding physical and chemical properties. Good performances of the coating showed after spraying, which were able to meet the application requirements.
