    • The surface of the member to be inspected is covered with powder deposited by using, for example, static electricity prior to the flaw detection. The member surface is covered so as to be partly exposed by setting the average thickness of the powder layer to 0.1D-0.6D, where D is the average particle diameter of the powder, under an assumption that the powder particles in the powder layer are virtually leveled into a uniform thickness film. Subsequently, the surface region of the member is heated by high frequency induction heating, and then the temperature distribution on the surface is measured with a radiation thermometer. The part for which the temperature measured is different from the surroundings is judged as a flaw. The surface of the member is covered with the powder so that the surface emissivity becomes almost uniform, and the resulting temperature distribution measured with the radiation thermometer becomes almost equal to the real one. Therefore, flaws existing on the surface of the member are precisely detected according to the measurement with the radiation thermometer even in the case that there are parts of low emissivity, such as handling marks, on the surface.
    • 要检查的构件的表面被覆盖有通过在缺陷检测之前使用例如静电而沉积的粉末。 通过将粉末层的平均厚度设定为0.1D-0.6D,其中D是粉末的平均粒径,在粉末层中的粉末颗粒为 几乎平整成均匀的厚度薄膜。 随后,通过高频感应加热来加热构件的表面区域,然后用辐射温度计测量表面上的温度分布。 测得的温度与周围环境不同的部分被认为是缺陷。 构件的表面被粉末覆盖,使得表面发射率变得几乎均匀,并且用辐射温度计测量的所得温度分布几乎等于实际温度分布。 因此,即使在表面上存在低发射率(例如处理痕迹)的部分的情况下,也可以根据辐射温度计的测量精确地检测到部件表面上存在的缺陷。
