Abstract Reactive magnetron sputtering was used to prepare (Al+Al2O3) diffusion barrier layer on SiC fiber surface. The relationships between deposition process parameters with composition and deposition rate of the coating, and the influence of the coating on mechanical property of SiC fiber were measured. Results show that with increasing sputtering power, the deposition rate increases rapidly at first and then slowly. With increasing of working pressure, the deposition rate of the coating deceases slowly at first, and then sharply at a typical value of working pressure, finally drops gradually. (Al+Al2O3) protected C-rich layer of SiC fiber, and improved the adherence between fiber and diffusion barrier layer. Results of laser Raman spectrum show that the coating has little influence on surface residual stress of SiC fiber. The measured tensile strength of the composite fibers is 97.69% of the calculated tensile strength according to meaning rule, and is 98.77% of the calculated one for the fiber after vacuum treatment at 850 ℃ for 10 h, meaning that (Al+Al$_{2}$O$_{3}$) coating has not much influence on mechanical property of SiC fiber.
