1 TARIFF A FILLER ALLOY FOR USE IN VACUUM SOLDERING. PRODUCTION METHOD Technical Area 5 The invention describes the formation of a composite of Ti6Al4V alloy with SiO₂(f) / SiO₂ by vacuum brazing. The invention relates to the filler alloy used in its assembly and the manufacturing method. Joining technologies for engineering materials, especially vacuum brazing and It is located in the field of metal-ceramic composite bonding techniques. It also includes fillers. Alloy modification and optimization of the interface microstructure are also technical aspects of the invention. It is part of the area. State of the Art Brazing is the process of joining two or more metal parts without melting the base materials. a filler metal with a lower melting point placed between them 15 It is the process of joining materials together. In this process, the base materials remain in a solid state. The solder alloy simply melts, wetting the surfaces, and the bonding occurs through capillary action. It spreads to the region, and after cooling, a metallurgical bond forms. Soldering is generally such as copper, brass, steel, stainless steel, aluminum, nickel alloys, and titanium. It is applied between metals. Furthermore, with appropriate interlayer and surface preparation, it can reach 20. It can also be used in ceramic-metal or composite-metal combinations. Especially in electronic circuits, heat exchangers, automotive and aerospace components, Soldering in systems requiring sealing and in precise assembly applications. It is a critical joining method. This method has lower costs compared to welding techniques. This is carried out at a temperature of 25°C. Thus, the geometric accuracy of the parts is preserved. and the risk of deformation in thin-section or heat-sensitive components is reduced. Soldering includes low-temperature soft soldering and high-temperature hard soldering. types such as brazing and those performed at even higher temperatures They are separated. Also, depending on atmospheric conditions, open atmosphere soldering, shielding gas There are also subclassifications such as atmospheric soldering and vacuum soldering. Among the advantages of soldering are the ability to join different metals. ensuring a smooth and leak-proof connection, suitability for mass production, and relatively low cost. While thermal stress is a factor, some disadvantages include reduced bond strength. 2 Lower cost compared to other welding methods, high sensitivity to surface cleaning. and the main material properties during high-temperature processing. There is a risk of change. Vacuum brazing is a brazing process performed in a low-oxygen, partial-pressure environment. This is achieved by, in particular, preventing surface oxidation and ensuring high purity. It is preferred in order to obtain homogeneous bonds. This method is used with titanium and titanium alloys (e.g., Ti6Al4V), nickel-based superalloys, stainless steels, among carbides, ceramic-metal combinations and advanced composite materials It is widely used to achieve high-performance connections. Vacuum 10 Thanks to its medium, there is no need to use flux. Thus, especially required in aviation, defense, medical implant and high temperature applications. Clean and controlled connections are ensured. Furthermore, the vacuum soldering process... This requires furnace systems with high investment costs, and process parameters (temperature, time, pressure) requires precise control and the filler used 15 Depending on the alloy, this can be achieved at temperatures exceeding 900 °C. These high temperatures cause phase transformations and grain changes in alloys such as Ti6Al4V. This can affect mechanical properties by causing growth. Therefore, most In order to prevent critical changes in the microstructure during the application, the processing time is one hour. It is kept short. On the other hand, silica-based materials such as SiO₂(f) / SiO₂ composites 20 It is more sensitive to high temperatures and becomes amorphous at temperatures above 870 °C. A transformation from the structural phase to the crystalline tridymite phase can occur. This phase transformation... significantly improves the mechanical strength and thermal expansion behavior of silica. It changes the material selection, temperature-time in vacuum soldering. This necessitates careful process design in terms of optimization and microstructural stability. 25 It makes it possible. The study by Huang et al., which is part of the state of the art, uses pulsed Nd:YAG. Addition of Zr to AgCu28-4.5Ti based active solder (AgCu28- The interface structure and its effect on performance in 4.5Ti-4Zr) Ti Gr.1–AISI 1045 joints 30 It examines them comparatively. The study includes both zirconium and non-zirconium products. Direct comparison of systems, combining SEM / EDS / XRD + hardness + tribology tests. Its use and the addition of Zr increase element diffusion and excessive brittle phases such as Cu3Ti. By reducing its formation, it provides more homogeneous hardness / interface and better ductility. 3 However, brittle reaction phases (especially Cu3Ti) are clearly observed in the study. It is being discussed, and there are signs of micro-crack risk and interface-related weaknesses. In addition, the bond strength (tensile / shear) and fracture starting from the interface There are also shortcomings in mechanical fracture tests that directly prove that it has not started. There are 5. In the current technique, high soldering temperatures are used, and these high temperatures... The resulting residual thermal stresses between SiO₂f / SiO₂ composite and Ti-6Al-4V The risk of cracks due to the mismatch in the coefficient of thermal expansion occurs at the interface. Brittle reaction phases, limited bond strength, and frequent joint fractures are common in 10 years. Due to issues such as starting in the interface region, there is a need for development in this area. It has been deemed necessary to do so.
