| Abstract: | The effects of processing parameters,suchas total gas flow rate,deposition temperature,TiCl_4 evaporation temperature and N_2/H_2 ratio, on the TiN deposition rate on W18Cr4V high speed steel substrate were studied.The conditions under which the deposition process is controlled by diffusion limited growth and surface limited growth process were determined respectively.In the region of surface process control,the apparent activation energy of TiN chemical vapour deposition on W18Cr4V steel substrates was measured and calculated,and its value is 137.23kJ/mol. |
