Abstract
W artykule przedstawiono wykorzystanie metody tomografii komputerowej CT (ang. Computed Tomography) do oceny powłok napawanych. Do otrzymania napoin wykorzystano metodę napawania elektrodą nietopliwą w osłonie gazowej TIG (ang. tungsten inert gas) z wykorzystaniem stopowych drutów do napawania powłok odpornych na zużycie o nazwach handlowych: EL-500 HB, EL-600 HB, EL-650 HB. Scharakteryzowano typowe wady wykonanych napoin oraz wpływ rodzaju drutu na koncentrację wad. Najmniejszy średni procentowy udział wad w stosunku do powierzchni całkowitej otrzymano dla napoiny EL- 600 HB, który wyniósł 1,5%.
Defects identyfication of padding coatings using X-Ray Mikrotomography method
Abstract
The paper presents the use of Computed Tomography (CT) for the evaluation of padding coatings. The method used to obtain a padding weld is pad welding with tungsten inert gas (TIG) using alloy wires for pad welding of wear resistant layers under the trade names: EL-500 HB, EL-600 HB, EL-650 HB. It characterizes the typical defects of obtained padding welds and the impact of the type of wire on the concentration of defects. The smallest average percentage of defects in relation to the overall surface is observed for the padding weld EL-600 HB, which amounts to 1.5%.
