Description
Technical field
The present invention relates to the preparation method of the anti-oxidant Si-Zr-Y infiltration layer of a kind of Nb-Ti-Si base alloy surface, be exclusively used in preparation production and the application of the anti-oxidant Si-Zr-Y co-penetration layer of Nb-Ti-Si base alloy surface, belong to the metal surface properties modification technical field.
Background technology
The silica-based polynary ultrahigh temperature alloy of niobium has high-melting-point, low density and good hot strength; it is potential high about the 200 ℃ hot metal structured material of comparable nickel base superalloy use temperature; but its high-temperature oxidation resistance is relatively poor; although the high-temperature oxidation resistance through this alloy after multi-element alloyed has had significant raising; but still can't satisfy actual service requirements, thereby need to be at its surface preparation protective coating to improve its high-temperature oxidation resistance.Silicide coating density is low, fusing point is high, good thermal stability, is suitable for the high-temperature oxidation resistant protection of ultrahigh temperature alloy.But single silicide coating is owing to fragility own causes being prone to crackle in it, can produce larger internal stress in the coating during simultaneous oxidation, causes surface film oxide to peel off and loses protectiveness, therefore needs to add other element and carry out modification to it.Zr, Y isoreactivity element are improving coating compactness and with the bonding force of matrix, the aspects such as antistripping ability that fall low-alloyed rate of oxidation and improve oxide film unusual effect are being arranged, the people such as Zhai Jinkun adopt stuff paste melting to prepare the Si-Cr-Ti coating of Zr and Y modification at the C103 alloy surface, find the significantly crystal grain of refinement coating of Zr and Y element, improve density and the adhesivity of coating, 1400 ℃ of constant temperature oxidation experiments show, Zr, Y modification can significantly improve the high-temperature oxidation resistance of coating.
In recent years, the research that relates to the silica-based polynary ultrahigh temperature alloy of niobium surface high temperature coatings is also few, existing work mainly concentrates on the preparation of C103 alloy surface coating, and method also is mainly stuff paste melting, mainly have following problem: the coating structure of (1) stuff paste melting preparation is comparatively loose, hole and crackle can appear in coatingsurface and inside inevitably, and prepared coating high-temp antioxidant property is unsatisfactory; (2) because the atomic radius of Zr and Y is large and fusing point is higher, diffusion in alloy is difficulty comparatively, the active atomic that is respectively oozed simultaneously element also can influence each other in absorption and diffusion process, the more single silicide infiltration layer of the process of growth of co-penetration layer is more complicated, and conventional diffusion is oozed catalyzer (such as NH
4Cl, NH
4F and NaBr etc.) be difficult to prepare and ooze altogether respond well co-penetration layer.At present, the technology of preparing of the oxidation resistant Zr of the silica-based polynary ultrahigh temperature alloy surface high-temp of niobium, Y modified silicide infiltration layer and application thereof still belong to blank.Therefore the technology of preparing of research and the oxidation resistant Zr of the realization silica-based polynary ultrahigh temperature alloy surface high-temp of niobium, Y modified silicide infiltration layer is significant in the application of the industrial circles such as aerospace to the silica-based polynary ultrahigh temperature alloy of niobium.
