The invention belongs to the improvement research of the corrosion-resisting property of a material of a novel structure, and particularly relates to an optimizing technology for improving the corrosion-resisting property of ZrCuNiAlTi block metal glass. The method is characterized in that alloy composition metal glass with the atomic percent of Zr52.5Cu17.9Ni14.6Al10Ti5 is taken as a base material, and through 15-minute annealing of 593K, the best corrosion-resisting property can be achieved. According to the method, Vit105 block metal glass is selected to be used as a research object, the glass is put below the Tg, annealing at different temperatures is carried out, samples in different degrees of relaxation states can be obtained, corrosion property tests in different solutions are combined, the influence of the annealing temperature on the corrosion property can be obtained, and the corrosion-resisting property of the Vit105 block metal glass is optimized. The higher practical value in profoundly knowing the block metal glass and scientifically and reasonably applying the novel functional materials can be achieved.
