| 摘 要： | 为了满足高温热防护的需求，采用等离子喷涂技术制备Ni3Al复合涂层，并详细研究了涂层的组织结构、结合强度、热震性能及高温抗氧化性能。结果表明，由于Ni、Al粉体之间接触充分，喷涂过程中，完全反应生成了Ni3Al中间相，并放出大量的热，涂层与基体呈微冶金结合，结合强度较普通镍包铝涂层高30%~40%，并具有良好的抗热震性和高温抗氧化性能 |

| Abstract: | In order to meet the need of high temperature thermal protection, Ni3Al coating was prepared by plasmas spraying technology. The microstructure, bond strength, thermal shock and anti-oxidation properties of the coating were studied. The results show that due to the full contact between the nickel powder and the aluminum powder, the Ni3Al intermetallic compound are completely formed during plasma spraying and a lot of heat is released. The coating and the matrix are of micro metallurgic bonding. The coating shows high thermal shock and anti-oxidation properties and its bond strength is 30% to 40% higher than that of the commercial NiAl coating |
| Keywords: | Ni3Al plasma spraying bond strength thermal shock oxidation |
