Abstract: Abradability and erosion resistance of the seal coatings were evaluated by sliding wear and erosion respectively. The results show that the mechanism of sliding wear is ploughing wear accompanying with adhesive wear and oxidation wear. The friction coefficient decreases because polyester film forms on the surface of the counterpart during wear. The erosion resistance of the coating is mainly dependent on the hardness, but polyester does increase erosion resistance at high impact angle due to its cushion effect.
