Abstract

Incoloy 800H was laser surface alloyed with SiC powders. Transmission electron microscopy examination of the alloy surface revealed that M₇C₃ carbides were precipitated in the melted zone. Such precipitation was caused by the decomposition of the SiC particles during the laser melting. Furthermore, it was found that the hardness of the surface-modified layer shows a pronounced increase after laser treatment.
