Description
Technical Field
The application relates to the technical field of powder metallurgy, in particular to a NiCrAlY alloy target and a preparation method thereof.
Background
The NiCrAlY coating has excellent compactness, can effectively isolate oxygen and other harmful gases in a high-temperature environment, has good oxidation resistance, can effectively resist hot corrosion of salt fog, high-temperature sulfide and other harmful substances, has excellent wear resistance, can effectively resist friction and wear in a high-temperature environment, prolongs the service life of equipment, and is widely applied to high-temperature corrosion working condition device protection in the fields of aerospace, ships and the like. Meanwhile, the NiCrAlY coating has good toughness and thermal fatigue resistance, can effectively resist the external force effects such as impact and vibration, is not easy to crack and peel off, has high bonding strength with the matrix metal, can be used as a bonding bottom layer of the thermal barrier coating, and improves the thermal expansion compatibility between the ceramic coating and the matrix.
The NiCrAlY coating is generally prepared by adopting a Physical Vapor Deposition (PVD) method, the preparation process is mature, the prepared coating has high quality, and parameters such as thickness and uniformity of the coating can be well controlled. PVD is a method for vaporizing a coating target material by a physical method (such as evaporation, sputtering, etc.), and depositing a film on the surface of a substrate, and has the advantages of low deposition temperature, high deposition speed, simple equipment structure, no pollution, etc.
The quality of the coated target material can have important influence on the coating performance, and the quality is mainly reflected in the aspects of purity, density, internal defects, grain size and the like. The higher the purity of the coating target material is, the lower the impurity element content in the coating is, and the better the PVD coating performance is, including corrosion resistance, optical performance and the like; the density of the coating target material is high, the coating speed can be improved, and meanwhile, the coating target material has certain strength and can better bear the thermal stress in the coating process; defects such as air holes, inclusions and the like in the coating target material can generate discharge phenomenon during coating, large liquid drops are formed, and the surface quality of the coating is affected; the smaller the grain size of the coating target material is, the coating speed can be improved, and the coating is more compact and uniform in thickness.
The film plating target material used for preparing the NiCrAlY coating is a NiCrAlY alloy target material. The NiCrAlY alloy target is usually prepared by adopting a vacuum melting casting process, and because the density and melting point difference of elements such as Ni, cr, al, Y are large, the burning loss of low-melting-point elements is easy to occur in the melting process, so that the control difficulty of the components of the NiCrAlY alloy target is increased, and binary alloys such as nickel-chromium, aluminum-yttrium and the like need to be prepared in advance, so that the preparation process is complicated. Segregation phenomenon easily occurs in the casting and forming process, so that the components of the target material are unevenly distributed, and defects such as air holes, looseness and the like easily occur in the target material, so that the preparation yield of the target material is reduced. Meanwhile, the smelting and casting process has the advantages of high energy consumption and high cost, and a large amount of pollutants such as waste gas, waste water, waste residue and the like can be generated in the process, so that a certain pollution is caused to the environment.
Based on the above, in order to improve the quality of the NiCrAlY alloy target and overcome the defects of low melting point element burning loss and segregation phenomenon easily occurring in the preparation process, it is necessary to find a new target preparation process.

Comparative example
Comparative example 1
The comparative example provides a NiCrAlY alloy target. The NiCrAlY alloy target differs from example 1 in that: ni powder and Al powder are not prealloyed in the preparation method. I.e. without the step of prealloying, the "powder mixing" step is as follows: and adding the Ni powder, the Al powder, the Cr powder and the Y powder into a three-dimensional mixer for uniform mixing to obtain the NiCrAlY alloy powder. The remaining operation steps were the same as in example 1.
In this comparative example, since Ni powder and Al powder were not prealloyed, the reaction exotherm of Ni and Al was large during hot isostatic pressing, the ingot melted, and the target preparation failed.
Comparative example 2
The comparative example provides a NiCrAlY alloy target. The NiCrAlY alloy target differs from example 1 in that: the material of the sheath used in the degassing step in the preparation method. In the step (3) of degassing, the NiCrAlY alloy powder is filled into an aluminum sheath, and vacuum heating and degassing are carried out. The remaining operation steps were the same as in example 1.
In this comparative example, since the capsule used in the degassing step is an aluminum capsule, ni reacts with the aluminum capsule during hot isostatic pressing, the ingot melts, and the target preparation fails.
Comparative example 3
The comparative example provides a NiCrAlY alloy target. The NiCrAlY alloy target differs from example 1 in that: the preparation process was not pre-sintered. I.e. the degassing step is directly followed by a hot isostatic pressing step. The remaining operation steps were the same as in example 1.
In this comparative example, since pre-sintering was not performed, the reaction exotherm of Ni and Al was large at the time of hot isostatic pressing, the ingot was melted, and the target preparation failed.
From comparison of the results of example 1 and comparative examples 1 to 3, it is understood that the sheath material of the pre-alloying and degassing steps of Ni powder and Al powder and the pre-sintering step are critical to the preparation process of the NiCrAlY alloy target. According to the method, the Ni powder and the Al powder are prealloyed through the impact ball milling of the zirconia balls, the ingot blank is placed into a heat treatment furnace for presintering after degassing, and alloying reaction between the Ni powder and the Al powder is performed in advance, so that the exothermic amount of the reaction between Ni and Al is greatly reduced when the ingot blank is subjected to hot isostatic pressing. The NiCrAlY alloy target is prepared by adopting a powder metallurgy process, and Ni and Al can undergo alloying reaction during hot isostatic pressing, particularly when the weight percentage of Al is high, the reaction heat release amount is large, so that the sheath is molten and leaks air, and the preparation of the target fails. The stainless steel sheath is adopted, powder does not react with the sheath material when the ingot blank is subjected to hot isostatic pressing, the risk of sheath melting and air leakage is further reduced, and the NiCrAlY alloy target is successfully prepared.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting thereof; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
