Hovercrafts are useful transportations because it can be operated both and water. Blades for hovercraft ara one of the most important part but it can be damaged by environmental factors. The erosion shield is applied to prevent erosion damage of the blades. Bonding properties between the blade and the erosion shield are very important. This paper is trying to identify the bonding characteristics according to surface treatment. In this study, three kinds of bonding layers and five kinds of surface treatment were applied. Test was achieved according to ASTM D 1002. From the test results, mechanical treatment like etching is the most effective solution than other chemical treatment and the impact absorption pad to reduce the impact damage decreases bonding strength within are experimented range.
