| Outline of Final Research Achievements |
Since it causes damage to the machine and deteriorates accuracy, it is necessary to securely fix the joint and the fastening part． Anｄ in general, there are many parts which are fixed by friction in various mechanical elements used in general industrial machines to medical implants. In such a friction interface, the dirt on the metal surface lowers the friction, so that it is necessary to stably express high friction. Therefore, we have developed a surface that stably develops high friction by providing minute unevenness to the surface, and clarified its effect and mechanism.

本課題では，限られた条件において高い摩擦を発現しなければならないような場合に効果的な摩擦係数の増加技術を開発した．例えば，医療用インプラントの小型化では，締結トルクが規定されており，新たな機構を追加することが難しい場合がある．そのような条件下では固定力を向上させるためにはなるべく安価に表面の摩擦係数を増加させることが肝要である．本課題では，安価な工業用レーザ加工装置を用いた摩擦係数向上技術を開発した．
