| Research Abstract |
To elucidate the relationships between wear resistance and microstructure of double layered ceramic coatings consisted of the partially stabilized zirconia/titanium nitride(TiN/PSZ) deposited on WC-Co cutting tools by thermal plasma CVD method, this research was carried out. TiN/PSZ double layer was successfully coated by using water vapor, which is introduced to the CVD equipment. When the amount of water was increased stepwise(step method), TiN/PSZ doubly coated sample showed a good were resistance. The cross sectional microstructure observations showed that the increasing an adherence between PSZ and TiN layers effectively increased the ware resistance than by densifing the PSZ over coated layer.
