Abstract

The types of defects and ways of their formation in the production of tiles from corundum ceramics are considered. The integrity of tiles containing artificial defects has been investigated by the method of active thermal nondestructive testing using optical heating. One- and two-sided thermal testing schemes as well as various methods of software processing of thermograms are applied. It has been established that the best results in detecting internal defects in ceramic tiles with a thickness of 10 mm during thermal stimulation using halogen lamps are obtained by the method of one-sided thermal testing.

刚玉陶瓷的热测试:光学加热下的传统技术
研究了刚玉陶瓷砖生产过程中的缺陷类型及其形成方式。通过使用光学加热的主动热无损检测方法,对含有人为缺陷的瓷砖的完整性进行了研究。应用了单面和双面热测试方案以及各种热图软件处理方法。结果表明,在使用卤素灯进行热刺激时,采用单面热测试方法检测厚度为 10 毫米的瓷砖内部缺陷的效果最好。

期刊介绍: Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
