This new solid aluminizing technique can lower the content of the aluminium powder to 10%.
以2∶1的氧化铝加木炭粉为填充剂,10%铝粉为供铝剂,3%氯化铵为催渗剂,可使铝粉含量降到10%的新型固体渗铝工艺,不仅能在钢铁表面获得厚而均匀的渗铝层,而且渗剂用后松散性好,试样表面光洁,不存在传统固体渗铝工艺的粘结问题,渗铝件的抗高温氧化性及耐蚀能力远远高于未渗件并可与不锈钢相媲美。
The morphology of Al-containing cementite,owing to its instability,changes rapidly from grain-boundary-network or pearlite lamella to fine dispersed particles during heating afterwards,giving excellent high temperature plasticity and hot-workability to the steel.
由于这种含铝渗碳体的不稳定性,在随后的加热中会迅速由喷射态的晶界网络形态或珠光体片层状转化为分散而细小的颗粒,从而使该材料具有很好的高温塑性和热加工性能。
