摘要/Abstract

摘要： 采用玄武岩制成喷涂粉末,用等离子热喷涂方法在45钢和铝基体上进行喷涂,从而形成一种新的矿物涂层.玄武岩粉末具有多棱状结构,主要化学成份为SiO_2、K_2O、CaO、Fe_2O_3、Al_2O_3,粉末颗粒尺寸范围80～200 μm,具有良好的流动性.采用SEM和XRD对涂层结构进行分析.实验结果表明:玄武岩涂层具有气孔和微裂纹,涂层组织结构主要为非晶结构,涂层与过度层均有良好的结合性.涂层最大厚度达到134 μm,显微硬度为593～928 Hv_(100).

Abstract: Basalt was used to produce powder, then the powder was used to spray on steel and aluminum plates with APS technology in order to create a new mineral coating. The powder of basalt appeared prismatic structure. Powder was mainly composed of SiO_2,K_2O,CaO,Fe_2O_3,Al_2O_3 and the size of them was in 80-200 μm range. The flowability of powder was better. The structure of coating was analysed by SEM and X-ray diffraction methods. The result of experiment shows that there are some holes and micro cracks on surface of coating and structure of coating is amorphous. The bond of coating with intermediate layer is better. The max thickness of coating is about 134 μm and micro hardness of coating is 593-928 Hv_100.
