Wind power and nuclear energy
Application Cases
In-core heat exchange components for nuclear power reactors
Plan
Equipment: SLM metal 3D printing equipment
Material: CuCr alloy powder
Craftsmanship: A finely structured heat-exchange flow channel is integrally formed via laser selective melting, with strict control of powder oxygen content to enhance resistance to neutron irradiation and high-temperature steam corrosion.
Application areas
Internal heat-exchange components of a small modular nuclear reactor.
Sliding bearing bushing
Plan
Equipment: Complete laser cladding system
Material: Copper-based alloy powder
Process: Laser cladding with synchronous powder feeding and layer-by-layer metallurgical bonding; the wear‑resistant coating on both the inner and outer surfaces of the bushing is formed in a single pass, achieving strong metallurgical adhesion between the coating and the substrate—eliminating the need for full‑body copper forging. To address the tendency of thin‑walled bushings to deform during machining, a segmented cladding approach combined with temperature‑controlled, adaptive processing is employed to reduce residual stresses, yielding a dense, uniformly microstructured wear‑ and friction‑reducing copper alloy coating. This significantly enhances the component’s wear resistance and corrosion resistance, making it suitable for both new‑part manufacturing and remanufacturing of worn components, while substantially shortening the overall fabrication cycle compared to conventional bulk machining.
Application areas
Construction machinery transmission bushings, hydraulic system shaft sleeves, marine propulsion sliding bearings, wear-resistant support components for metallurgical equipment, and high-speed, heavy-load rotary bushing parts.
