Experimental analysis shows improved fiber compatibility in aluminum matrix using copper coating, highlighting its structural significance.
The effect of a barrier copper coating on reinforcing carbon fibers on their compatibility with an aluminum matrix (wrought alloy AD31 of the Al-Mg-Si system) has been studied. The coating was applied by galvanic deposition from acid and alkaline electrolytes at room temperature. No coating was applied to the SiC fibers. The samples were obtained by spontaneous impregnation at temperatures of 700-950 °C in a vacuum with a residual gas pressure of 0.1 Pa. The microstructure of the fiber-matrix bonding areas was studied. It is shown that the coating formed from an alkaline electrolyte ensures better wetting of the fiber by the matrix melt.
