Seizure and Friction Properties of the DLC Coated Journal and Aluminum Alloy Bearing

Using a bearing tester that can control the relative positional relationship between the shaft and the bearing in parallel, the seizure and friction property of the combination of a-C:H:Si DLC coated journal and the aluminum alloy bearing were verified. In case of the shaft rotation speed was 5200 r...
