Outline of Final Research Achievements

This study was investigated on the water repellency and producing ceramics layer of modified surface under the wood surface was rubbed by high-speed friction on the tools with smooth surface. The result indicated that the coated layer affected by the thermal and mechanical actions on the high-speed friction could be produced in the range of 1mm from wood surface. Such modified surface layer also provided the water repellency same as painted wood surface. Furthermore, the change of the wood temperature under the high-speed friction depended on the surface applied pressure. The results classified that the controlling the applied pressure might be possible to control the wood temperature up to the high thermal condition.
