摘要： A heat treatment method for improving the mechanical property and the biofunctional stability of a magnesium alloy is provided, comprising: (1) fully annealing an original cold-drawn magnesium alloy AZ31; (2) polishing a surface of the magnesium alloy AZ31 from the step (1) by a waterproof abrasive paper; (3) heating the magnesium alloy AZ31 obtained from the step (2) to a temperature of 330° C. to 350° C. and keeping the temperature for 3 to 4 hours; and (4) cooling the magnesium alloy AZ31 obtained from the step (3) to room temperature. A method for manufacturing a small-peptide-coated biomaterial and an application of the small-peptide-coated biomaterial are further provided.
