Abstract

Alloys based on Ti3Al intermetallic compounds have assumed considerable importance in aerospace and automotive industries, because of their high strength to weight ratio and excellent creep resistance up to 800°C. One such alloy is Ti-23Al-11Nb-0.9Si(at.%) which shows attractive creep properties. Nevertheless, the alloy suffers from relatively poor resistance to OXIDATION at high temperatures. To improve this, the alloy was coated by immersing in Al-7wt%Si liquid followed by DIFFUSIONAL ANNEALING at 850 ◦C for 5, 10 and 15 hours. Microstructure studies revealed that coatings were consisted of exterior TiAl3 and interior TiAl layers. To study the effect of coating on OXIDATION behavior of the alloy, isothermal and cyclic OXIDATION tests were carried out before and after coating. The results showed that the OXIDATION resistance of the coated samples were much better than those of uncoated ones. This was due to the formation of a thin α-Al2O3 layer on the coating surfaces.
