Document Type and Number:
Japanese Patent JP2022135273
Kind Code:
A
Abstract:
To provide a shape protection method for fine unevenness formed based upon fine particle projection processing.SOLUTION: The present invention relates to a fine unevenness shape protection method that subjects a surface which has numberless fine unevenness formed at random based upon fine particle projection processing to a DLC coating treatment so as to protect the fine unevenness shape of the surface, wherein a DLC coating has a film thickness of less than 1 μm, the fine unevenness after the DLC coating treatment has an unevenness pitch of 2.4 to 30 μm, and a recess part depth related to the unevenness pitch is 0.2 to 3 μm. Alternatively, the DLC coating has a film thickness of less than 0.3 μm, the fine unevenness after the DLC coating treatment has an unevenness pitch of 0.4 to 7.3 μm, and the recess part depth related to the unevenness pitch is 0.04 to 1.0 μm.SELECTED DRAWING: Figure 4
