Purpose: Increasing oxidation resistance of TiAl intemetallic alloy by gas phase aluminising. Design/methodology/approach: The structure of coatings was investigated by light scanning microscopy. The chemical composition of coatings was investigated by EDS method and XRD phase analysis was used as well. Findings: The investigation has showed that the thickness of the coatings was 10 micrometres. The structure of the silicon-modified aluminide coatings is as follows: the outer zone consisting of TiAl3 phase (on the TiAl7Nb alloy only), the middle zone consisting TiAl2 phase, the inner zone consisting of TiAl phase. The analysis of the average chemical composition of the outer zone exhibited the gradual increase of the silicon content along with the increase of this element in the slurry. Practical implications: The slurry method can be applied in aerospace and automotive industry as low-cost technology of producing of aluminide coatings on intermetallics. Originality/value: New method of depositing of aluminide coatings on TiAl alloys.
