研究硼化钛加工工艺是为了生产高质量扬声器振膜。把钛振膜埋在硼、碳和碳酸钠的混合粉末内加热,在振膜表面生成 TiB 和 TiB_2钛硼化物。25μm 厚的钛振膜在1200℃处理10分钟,即可得到杨氏模量 E=2.5×10~(11)N/m~2,密度ρ=4.2×10~3kg/m~3,硼化深度为5μm 的振膜。硼化钛的 E/ρ比率约为钛的2.5倍。使用硼化钛振膜,可使宽频带、低失真的扬声器获得最佳的瞬态响应。 Research titanium boride processing technology is to produce high-quality speaker diaphragm. The titanium diaphragm buried in boron, carbon and sodium carbonate mixed powder heating, the surface of the diaphragm to generate TiB and TiB_2 titanium boride. 25μm thick titanium diaphragm at 1200 ℃ for 10 minutes, you can get the Young’s modulus E = 2.5 × 10 ~ (11) N / m ~ 2, the density ρ = 4.2 × 10 ~ 3kg / m ~ Diaphragm with a depth of 5μm. Titanium boride has an E / p ratio of about 2.5 times that of titanium. Using titanium boride diaphragm, broadband, low distortion loudspeaker for the best transient response.
