Abstract

A type of lead-free compensation mud is designed for steel materials radiography inspection. The compensation mud is mainly composed of barium sulfate, tantalum and ultralight clay in a certain proportion. The radiation attenuation coefficient of the compensation mud is approximately same as steel. The lead-free mud is convenient and harmless to inspection, which can be moulded freely according to the shape and size of the detected object. It is considered that the film density difference between the mud and steel changes non-linearly with the proportions of the components upon the theoretical analysis. The radiography experimental data analysis shows that the respective component ratio of compensation mud should satisfy the special linear equations to acquire the same attenuation coefficient as steel. Some workpieces such as aircraft turbine blade, bolt and propeller shaft with complex shape and large mutation size have been radiography inspected with the designed mud. The negative images indicate the details of structures and defects without edge erosion effect.
