W-Cu　composites　are　commonly　subjected　to　coupled　multiple　fields　in　service,　which　imposes　high　requirements　on　their　overall　performance.　In　this　study,　the　ultrafine-grained　W-Cu　composite　was　fabricated　using　the　combination　of　electroless　plating　and　spark　plasma　sintering.　The　wear　resistance　and　high-temperature　compressive　properties　of　the　ultrafine-grained　W-Cu　composite　were　investigated　and　compared　with　those　of　the　commercial　coarse-grained　counterpart.　Moreover,　the　underlying　strengthening　and　wear　mechanisms　were　also　discussed.　Here　we　show　that　the　ultrafine-grained　W-Cu　composite　exhibits　superior　integrated　mechanical　performance,　making　it　a　potential　alternative　to　commercial　W-Cu　composites.
