| Abstract: | The important factor induced corrosion damage of navy aircraft was analyzed.Based on the military airport ground environmental spectrum,the LY12CZ and other materials samples were tested in laboratory,by use of the accelerated corrosion spectrum.Using microscope,the corrosion characteristic of the coating and base material was inspected and corrosion damage size was measured after the sample had been accelerated corrosion tested for 5,10,15,20,30 years respectively and the sample had been exposed on ship.Th... |
