| Objective To study the performance of BT-2G steel rust removal and rapid phosphating paste, ALT-1 aluminium alloy rust removal paste and LYG-2 aluminium alloy partial oxidation paste which are developed by ourselves. Methods The appearance, the mobility and the reaction time of different pastes were observed and tested, the coating binding force and the hydrogen embrittlement of BT-2G were studied as well as the rust removal efficiency and the corrosivity for matrix of ALT-1 and the coating binding force and the corrosion resistance of LYG-2. Results The pastes were uniform thick liquids, the mobility was less than 1 mm, the process can be completed within 3 h. Moreover, the samples which were treated with BT-2G can pass the test of coating binding force and hydrogen embrittlement, the rust removal efficiency of ALT-1 was above 90%, ALT-1 had no corrosion influence on matrix. The samples treated with LYG-2 can pass the test of coating binding force and there was no corrosion after neutral salt spray for 72 h. Conclusion The pastes can satisfy the request of airfield maintenance, and can be applied in the aircraft maintenance/ repair. |
