AI Technical Summary
Existing zinc-aluminum-magnesium multi-element co-diffusion methods have problems such as uneven diffusion layer thickness, low density, high heating temperature, long holding time, significant impact on matrix strength, incomplete diffusion into slender tubular workpieces, and complex equipment structure and high cost of pure gas phase co-diffusion methods.
A solid-gas alternating co-diffusion method for zinc-aluminum-magnesium alloys, which couples mechanical and chemical activation, is adopted. By expanding mechanical energy in two stages, a mechanical activation system is constructed. Combined with zinc-aluminum-magnesium alloy infiltrating agents and composite activators such as ammonium chloride, the spatiotemporal coupling of mechanical and chemical energy is achieved, replacing part of the thermal energy, to activate the workpiece surface and diffuse the infiltrating agent elements.
It achieves low-temperature, short-time, and efficient co-infiltration, ensuring the quality of the infiltrated layer and maintaining the strength of the matrix. It is suitable for complex structural workpieces, provides all-round uniform co-infiltration, reduces production costs, and meets the requirements of green and low-carbon development.
