【摘要】 在含氯化铝的固体沉积剂中加入2%的乙酸钠可提高低、中碳钢TiC层的硬度,并能增加低碳钢沉积层深度;加入1%稀土氯化物,可显著提高TiC沉积效率。在所研究的固体渗剂上部填充5～10mm厚的SiO₂粉末,在850～1000℃下,可形成硅酸铝及SiO₂的板结保护亮,具有良好密封性.并可提高TiC沉积层的致密度。更多还原

【Abstract】 The aluminium chloride is an active agent in the pack TiC deposition. The deposition hardness of low and medium-carbon steels and the deposition thickness of lowcarbon stsel are increased, if adding 2%CH₃ COONa to the deposition agent containing aluminium chloride. The TiC deposition efficiency will be increased considerably, if adding rare 1% earth chloride to the deposition agent contained 5%aluminium chloride.A protected crust, which consists of Al₂ （SiO₃）_? and SiO₂ can be formed on the surface of deposition agent at 850～1000℃, if adding S₁O₂ powder with thickness5～10mm, outside the coating agent. The protected crust offers a good airproof property and increases the density of coating.更多还原
