Abstract:Using organic-metallic compound TPT as the source of Ti , H13 mould steel was coated Ti(CN) layer by PCVD technique, the effects of coating technics on the structure and micro-hardness and the anti-oxidation property of Ti(CN) layer were investigated. The results show that under the appropriate temperature and pressure, one layer mostly of Ti(CN) is formed on the steel surface which has highest micro-hardness of HV1760 at 500℃,and the anti-oxidation property of the layer is significant below 600℃.
Key words: PCVD; Ti(CN) layer; anti-oxidation property
