Research on fast nitriding by direct current field base on the deep-layer QPQ technology

摘要：

In recent years the QPQ technical innovator is the development and application of deep-layer QPQ. But also brings a lot of problems need to solve. This article introduces a new technology use direct current field at low temperature and short time base on the deep-layer QPQ. Use 45＃ as material, we make a comparative between DC treatment and normal treatment at the same condition. The results show that the DC treatment was beneficial forms of the nitrided layer and the performance index was the same as normal treatment. The formation of the nitrided layer in the direct current field situation is analyzed.
