Technical field:
The present invention relates to material science, a kind of nanocrystalline composite coating and preparation method thereof is provided especially.
Background technology:
In the prior art, the gas turbine development of technologies is subjected to the considerable restraint of material technology and design.In the technical development process, the development of structure-design technique, technique for cooling blades, high temperature casting alloy technology has all improved the efficient and the power of gas turbine effectively.From the sixties in 20th century, the MCrAlY coating is widely used in the abominable turbine blade of gas turbine technology of operational factor height, environment because of its good oxidation resistance.But people find that in actual use the performance of this coating depends on different preparation methods' use to a great extent.Trace it to its cause, when using different preparation methods, even the chemical composition of coating is identical, the coating microstructure that diverse ways is prepared is also different.In the prior art, the manufacturing cost of nanocrystalline coating is often higher, and coating (especially under high temperature or corrosive environment) under specific condition is when using, and the life-span of coating can sharply shorten.Therefore, seek a kind of method that can improve the anti-oxidant of MCrAlY coating and heat erosion ability, important and practical meanings is arranged.
In the prior art, common MCrAlY type coating is a heterogeneous alloy, and when wherein aluminium content was low, the parent phase of alloy was the face-centered cubic plasticity solid solution phase of Ni or Co preferably; When the Al content in the alloy was higher, owing to separating out of fragility phase, the fragility of alloy increased, and the processability of material is sharply descended, and high Al content is crucial to high-temperature oxydation and the hot corrosion resistance that improves coating.
When the composition of metal material is identical, the crystallite dimension difference, i.e. crystal boundary volume difference can change the high-temperature oxydation speed of material significantly, and we are referred to as grain boundary effect usually in the present technique field.Nanocrystalline coating is compared with the coarse-grain coating of identical component, crystal boundary volume fraction height, crystal boundary is as the rapid diffusion passage, grain boundary effect is obvious, not only can significantly improve the resistance to high temperature oxidation and the hot corrosion resistance of coating, and changed the oxide-film composition, make when Al content is low in the alloy and still can generate stable Al
2O
