Mg/PTFE thin film pyrotechnic was produced by magnetron sputtering and evaporated deposition using magnesium as the combustible and polytetrafluoroethylene as the oxidant. The differences of the two film technologies were investigated and the adhesion,the granularity and the burning rate of the thin film were measured. Results show that the adhesion,the granularity and the burning rate of the Mg/PTFE film produced by magnetron sputtering are 35.88 mN, 0.1-0.5 μm and (623.9±12.5) mm·s^-1 respectively,and the main performances of the Mg/PTFE film produced by magnetron sputtering are better than that by evaporated deposition.
