Active Brazing Filler Technology
Active brazing technology uses solders with active elements like titanium to directly join ceramic materials. This creates a chemical bond without prior metallization.
Physical-Chemical Mechanism of Action
Active brazing technology utilizes solders with elements like titanium that have strong reducing properties. These solders react chemically with the surface material and form a metallic bond. This allows ceramic materials to be joined directly without prior metallization.
Metallurgical Relevance & Risks in Welding
Active brazing technology is particularly useful for joining metallic and non-metallic materials. It avoids the complexity of metallization and can achieve higher strength and chemical stability of the joint. However, improper use or insufficient purity of the solders can lead to contamination or lack of bonding, resulting in cracks or damage to the joined materials.
Workshop Practice & Instructions
To successfully use active brazing technology, it is important:
• Keep the solders clean and free from contaminants.
• Select the correct solders for the respective material.
• Carefully control the temperature and time of the joining process to achieve an optimal bond.
• If necessary, perform post-heat treatment to increase the strength of the joint.
