要求浅层(0.1～0.5mm)渗碳的零件,往往对变形的要求也比较严格,多数此类零件尺寸小而形状复杂,若采用常规工艺渗碳,不仅变形难以控制,而且渗层易超深和不均匀,为此我们采用低温渗碳工艺。经反复试验和小批量投产获得满意的结果,它具有工艺稳定可靠,渗碳速度快无毒等优点。试验材料相当模数为3的20CrMnTi钢制的200卡盘卡爪。渗碳为:碳粉77%,碳
Requirements of shallow (0.1 ~ 0.5mm) carburizing parts, often on the deformation of the more stringent requirements, the majority of such parts small size and shape complexity, if the conventional carburizing process, not only difficult to control the deformation, and easy to super-permeability layer Deep and uneven, for which we use low-temperature carburizing process. After repeated trials and small batch production to obtain satisfactory results, it has a stable and reliable process, carburizing fast non-toxic advantages. Test material The equivalent modulus of 20 20CrMnTi steel 200 chuck claws. Carburize as: Toner 77%, carbon
