304 マグネシウム合金における硬度傾斜機能を有したDLC処理プロセスの構築

抄録

The aim of this paper is to improve the tribological properties of Mg alloy by DLC film. Especially, the influence of Functionally gradient DLC film on wear properties was experimentally carried out. The main results obtained are as follows; (1) As results showed that wear resistance of DLC/Cr80% material which added Functionally gradient to 80% in the DLC film improved over 2 times compare with DLC/Cr20% material. (2) The strain difference in the interface which seems to be a cause of the separations of film was examined using FEM analysis. As results showed that strain difference of DLC/Cr80% material reduced compare with DLC/Cr20%.
