高速钢上Ti-N镀层的残余应力分析

Residual Stress of Ti-N Coatings on High Speed Steel

采用X射线衍射的0～45°法,对沉积在高速钢上的Ti-N镀层的残余应力进行了测量。结果表明,残余应力为压应力(σ_(?)<0),值域为8～12 GPa,同时对影响镀层残余应力的各种工艺参数进行了评估。

The X-ray diffraction 0～45°method can be used to determine the residual stress of Ti-N coating deposited on high speed steel (HSS). The results show that the residual stress is compressive stress (σ_φ, <0). Its values are between 8 GPa and 12 GPa. The various technological parameters affecting the residual stress of the coating are assessed.
