众所周知:固体渗碳剂的基础是由硬木材制造的木炭。被炭块吸附的氧与碳呈下列反应:2C+O_2→2CO为了提高渗碳剂的活性,木炭中通常都加碳酸盐:如碳酸钡、碳酸钙、碳酸钠等。试验证明:用锯木屑代替木炭,并加一定份量的碳酸钠作催化剂,能得到良好的效果。其成份如下:渗碳剂Ⅰ:含木屑50％,木炭30％,碳酸钠20％;渗碳剂Ⅱ:含木屑80～85％,碳酸钠20～15％。渗碳试验的结果证明.这些渗碳剂的活性,都较一般的渗碳剂(如75％的木炭,9％的碳酸钠,18％的碳酸钡)为佳。其扩散层的深度都在10％以上。这是因为木屑在干馏过程中,除生成
It is well known that solid carburizing agents are based on charcoal made from hard wood. Oxygen adsorbed on the carbon block reacts with carbon in the following reactions: 2C + O 2 → 2CO In order to increase the activity of the carburizing agent, carbonates such as barium carbonate, calcium carbonate and sodium carbonate are usually added to the charcoal. Test proved: sawdust instead of charcoal, and add a certain amount of sodium carbonate as a catalyst, can get good results. Its composition is as follows: Carburizer Ⅰ: 50% of wood chips, 30% of charcoal and 20% of sodium carbonate; Carburizing agent Ⅱ: 80-85% of wood chips and 20-15% of sodium carbonate. Carburizing test results show that these carburizing agents are more active than the average carburizing agent (such as 75% charcoal, 9% sodium carbonate, 18% barium carbonate). The depth of its diffusion layer are more than 10%. This is because wood chips in the distillation process, in addition to generation
