AbstractSiCf/Ni-Cr-Al precursor wires were obtained by deposition of (Al+Al2O3) diffusion barrier layers and Ni-Cr-Al alloy coating on the surface of SiC fiber via magnetron sputtering. The morphology, composition and phases of the coatings were studied, and the influence of the coatings on the mechanical properties of SiC fiber was investigated. The precursor wires were treated in vacuum at 850 degrees C and 900 degrees C for 150 h. The results show that (Al+Al2O3) coating is uniform and dense, the Al2O3 coating is amorphous, and the composition of Ni-Cr-Al alloy coating is close to that of Ni alloy target. The (Al+Al2O3) layer and Ni-Cr-Al layer combine well with SiC fiber and have extremely slight negative effect on the tensile strength. After heat treatment of the precursor wire in vacuum, the Ni-Cr-Al alloy coating remains intact, and Al2O3 coating effectively blocks the element diffusion and restricts the reaction between SiC fiber and Ni-Cr-Al alloy, which can ensure the preparation of high performance SiCf/Ni-Cr-Al composites.
