| 英文摘要 | The lifetime of traditional thermal barrier coating with one layer bond coating is limited by the insufficient oxidation resistance. A thermal barrier coating with a double-layer bond coating was prepared by HVOF and APS. Vacuum heat treatment was carried out prior to the top coating. Oxidation resistance of the thermal barrier coating was researched. The results show that the content of beta-(Co, Ni)Al phase increases from 13.91% to 27.78% after 1050 degrees Cx3 h vacuum heat treatment, and the distribution is more homogeneous. The roughness of HVOF sprayed bond coating is decreased by vacuum heat treatment. The roughness of vacuum heat treated bond coating increases from 7.2 mu m to 10.4 mu m by the introduction of APS layer, and the bonding strength of thermal barrier coating is up to 39.4 MPa. The mass gain rate of thermal barrier coating is 0.1719 g/m(2).h after oxidizing at 1050 degrees C for 200 h, which is consistent with antioxidant level of aviation industry standard. The bond coating sprayed by APS is sacrificed to oxidize prior to HVOF layer. The stress tolerance of bond coating/top coating interface is improved, and the lifetime will be extended. |
