我厂摸索出了一种适合于我厂生产条件(RJJ-39-9-TG气体渗碳炉)的成本低廉的防渗碳涂料。其配方为: 黑色氧化铜(CuO) 46.8% 红丹粉(Pb_3O_4) 26.6% 滑石粉 26.6% 另加浓度为10%的水玻璃适量。配料调匀后涂覆在工件上,厚度为3mm,以工件完全倒转时涂层不淌滴为宜。在100℃以下烘烤4小时后即可装入渗碳炉。这种防渗碳剂能确保渗碳时涂层不起皮、不开裂、不脱落;淬火时能自行崩脱。生产实践表明,用这种防渗剂处理的工件质量稳定。
I plant to explore a suitable for my factory production conditions (RJJ-39-9-TG gas carburizing furnace) cost-effective anti-carburizing coating. The formula is as follows: black copper oxide (CuO) 46.8% reddish pink (Pb_3O_4) 26.6% talc 26.6% plus the concentration of 10% water glass amount. After the ingredients are evenly coated on the workpiece, the thickness is 3mm, and the coating is not dripped when the workpiece is completely reversed. Bake in below 100 ℃ 4 hours after the carburizing furnace can be loaded. This anti-carburizing agent to ensure that the carburizing coating can not afford skin, no cracking, no shedding; Quenching can collapse itself. Production practice shows that the quality of the workpiece treated with this impermeable agent is stable.
