【Abstract】 With the organometallic compound propyl titanate TPT instead of TiCl 4 as the source of Ti,a Ti(CN) layer was deposited on the surface of tool steel H13 by PCVD technique.Effects of the process parameters on the structure and microhardness were investigated.The results show that under a appropriate depositing temperature,pressure and flux of nitrogen,a compact layer mostly consisting of Ti(CN) can be formed on the surface of tool steel,which can enhance the microhardness and improve the service life of tool steel significantly.更多还原
