Wet Blast and its application are expected to improve the friction characteristics of sliding parts. However, the friction characteristics of the sliding parts which are treated by Wet Blast are not clarified. In this study, the friction characteristics of a journal bearing treated by Wet Blast were examined using a bearing tester. As a result, we obtained the following findings: 1. The friction characteristics is affected by the size of polishing particles. The larger the particles becomes, the better the friction characteristics is achieved. 2. The friction characteristics is also affected by the blasting duration and improved by the proper blasting duration.
