| Outline of Final Research Achievements |
TiB2-MoS2 composite films were prepared as coating materials for cutting tools. The friction coefficients of the composite films at room temperature were 0.1 and their friction coefficients became as low as 0.01 at 200℃. Surface of wear tracks of the composite films was rather smooth and B oxidaized after sliding at 200℃. These are due to the formation and melt of B2O3 on the sliding surface of the composite films.
