Laser surface alloying was employed to prepare a novel W-Cu/Cu composite with high W content on the surface but low W content for the whole composite, exhibiting a lower arc ablation rate than the commercial one. The study opens a door to overcome the trade-off of the ablation resistance and W consumption of the W-Cu electrodes.
It is a long-term requirement to reduce the arc ablation rate and the W content of W-Cu composites. In this work, laser surface alloying was employed to prepare a novel W-Cu/Cu composite that contained a high W content on the surface but a low W content for the whole composite. The new W-Cu electrode exhibited a lower arc ablation rate than the commercial one. The underlying mechanism was attributed to the higher thermal conductivity of the new W-Cu/Cu composite with the low W consumption as a whole. This study opens a door to overcome the trade-off of the ablation resistance and W consumption of the W-Cu electrodes.
