Abstract: A lubrication mechanism of a strain wave gearing is disposed in an interior space of an externally toothed gear and comprises a powder-accommodating bag that stores solid lubricant powder. A diaphragm of the externally toothed gear is repeatedly deflected during the driving of the strain wave gearing. Vibration or deflection is repeatedly imparted to the powder-accommodating bag and the solid lubricant powder is discharged from a powder discharge hole formed in the powder-accommodating bag into the interior space. A site to be lubricated is lubricated with the solid lubricant powder discharged into the interior space. Harmful effects due to a large amount of the solid lubricant powder being supplied to the site to be lubricated at one time can be resolved, and a necessary amount of the solid lubricant powder can be continuously supplied to the site to be lubricated.

Abstract: To provide a sliding member comprising a coating film exhibiting constant and stable chipping resistance and wear resistance and excellent in peeling resistance (adhesion), and the coating film thereof. The above-described problem is solved by a sliding member (10) comprising a coating film (1) on a sliding surface (16) on a base material (11). The coating film (1) has, when a cross section thereof is observed by a bright-field TEM image, a total thickness within a range of 1 μm to 50 μm, in repeating units including black hard carbon layers (B), relatively shown in black, and white hard carbon layers (W), relatively shown in white, and laminated in a thickness direction (Y). In the black hard carbon layer (B) and the white hard carbon layer (W) adjacent to each other, the white hard carbon layer (W) has higher hardness and a larger [sp2/(sp2+sp3)] ratio than the black hard carbon layer (B).

Abstract: Provided are a coating film, a manufacturing method for the same, and a PVD device that not only sufficiently improve the balance of low-friction properties and wear resistance, but also improve chipping resistance and peeling resistance. This film is coated on a substrate surface, wherein the coating film has a hard carbon that presents relatively black and white when observed in a cross-sectional bright-field TEM image, a mesh-shaped hard carbon layer is formed using a PVD method, said layer having white-colored hard carbon in a mesh shape extending in the thickness direction and black-colored hard carbon dispersed into the cavities in the mesh, and the ID/IG ratio is 1-6 when the mesh-shaped hard carbon layer is measured using Raman spectroscopy, said ratio being the ratio of the Raman spectrum D band peak area intensity and G band peak area intensity.
