| Outline of Final Research Achievements |
Effects of deposition and heat treatment processes on texture formation are discussed. Independent of gas flow rate, fiber texture where the (0001) plane of Al2O3 tilted about 15 deg. from coating plane has formed. With the increase in gas flow rate, volume fraction of fiber texture has developed. The position of main component in the fiber texture has explained by the activation of basal and pyramidal slip systems with the consideration of critical resoled shear stress. After heat treatment of Al2O3 film, (0001) fiber texture which is effective for the cutting tool has formed. This may be due to the lowest surface energy of (0001) plane than other planes. Regarding the Ni film, {011} fiber texture has formed. With the increase in gas flow rate, volume fraction of fiber texture increased. By the comparison of maximum pole density on texture of Ni film and Ni bulk material deformed under uniaxial compression, it seems that the Ni film has deformed about -1.0 ～ -1.5 in true strain.
