Abstract
The surface of TC4 titanium alloy was strengthened by powder-mixed near-dry EDM with different proportion of B4C and Al powder. The microstructure, wear resistance and strengthening time were analyzed and studied. The results show that the microstructure and strengthening time of the strengthened layer are affected by different proportion of powder. With the increase of B4C content, the thickness of strengthening layer increases, and with the increase of Al content, the strengthening time decreases. When the proportion of B4C to Al powder is 2:1, the microstructure appearance is the best, the petal structure is compact and the cracks are few, the thickness of strengthening layer is the largest, and the wear resistance of the strengthened layer is about 3.8 times as much as that of the substrate.
