Laser cladding of layered Zr/Cu composite cathode with excellent arc discharge homogeneity

The surface-modified composite cathode is a promising candidate in alleviating arc ablation while retaining the matrix conductivity. In this work, mono-layered (ML) and bi-layered (BL) Zr/Cu claddings were prepared on the copper substrate through laser cladding. The arc ablation behaviors of BL Zr/C...
