Alumina borate whisker reinforced aluminium metal matrix composites were ultrasonically brazed in air. The liquid filler metal (FM) of a Zn-Al eutectic alloy could get into the clearance between composite couples by the action of ultrasonic capillarity. The velocity of the FM getting into the clearance decreases with increasing clearance width. The time exhausted to remove completely the oxide film on the surface increases with increasing clearance width. The oxide film could be removed completely and the metallurgical bonding formed under the action of ultrasonic vibration for sufficient time. The shear strength of the bond could reach up to 145 MPa (the nominal strength of the Zn-Al filler alloy).

“…This occurs because the particles of high-strength boron fibers coming into weld material reinforce it and promote strengthening. 16 To prevent metal composite melting, an adding material (Cv-AK5 wire) is used to fill gap and to form joint. This wire is supplied into the weld zone on the heating source side.…”

This work deals with the application of new approaches to welding production of modern light, strong, and heat-resistant metal composite materials in aeronautical and space technology. The objective of this article is to substantiate introduction of modern technology for welding composites in production, namely the development of argon-arc welding technology and the choice of equipment when using composites of the Al-B system for manufacturing the flame tube of the combustion chamber of an aircraft engine. Based on the study of technical literature and scientific publications, a short analysis of the existing technological processes for welding heat-resistant glass-ceramic composites was carried out. The problems arising in the process of welding aluminum composites reinforced with boron and steel fibers are considered. A modern gas tungsten arc welding based on new technological processes is offered with an example of welding in manufacturing a combustion chamber of a modern gas turbine modified engine.

Particle-reinforced aluminium metal matrix composites were ultrasonically brazed. In situ compositing technology of a particle-reinforced bond is described in this article. The joints with lower strength showed a structure of composite material/bond metal/composite material after ultrasonic brazing. The double liquid–solid zones in the base material close to the bond were fabricated by means of melting the base materials at a relatively higher temperature. Then pressure was applied to the samples, the double liquid–solid zones and the bond were mixed with each other and a particle-reinforced bond formed. The microstructure of the particle-reinforced bond is very similar to that of the base composite materials. The shear strength of the bonds was improved dramatically.
