Abstract

The results obtained via the nondestructive evaluation of reaction-bonded silicon carbide components after the machining of carbonized and siliconized bodies are presented. It was shown that visual-optical and capillary tests are capable to detect the surface defects such as pores and cracks. More often the defects appear on type 1 and 2 components after milling. Extended linear indications, which are common for cracks, were not detected on type 3 components after having been sandblasted and grinded.
