AI Technical Summary
Existing cold spraying technology has the problem of uneven composition when preparing composite materials, especially when using dual (multi) powder feeders, which leads to poor performance of composite materials in harsh environments.
The system employs a multi-channel powder feeding spray gun combined with a vibrator. The powder is divided into a powder feeding branch and a spraying branch via a high-pressure air source. After the powder material is mixed and heated in the premixing chamber, it is vibrated in situ using a vibrator on the outer wall of the spray gun to ensure that the powder is uniformly mixed and collides with the substrate to form a composite coating.
It achieves more uniform composition of composite materials, improves the mechanical properties of cold-sprayed composite materials, simplifies the operation process, improves work efficiency, and is suitable for the efficient repair of composite material parts.
