A surface treatment method for preventing adhesion of powder to a powder-contacting member having a surface on which contacted powder flows in the form of a particle layer. The method includes performing surface treatment on the surface such that an arithmetic average peak curvature Spc (1/mm) of the surface is 150 to 400, a peak density Spd (piece/mm) of the surface is 10000 to 180000, a root mean square gradient Sdq of the surface is 0.05 to 0.30, and an arithmetic average height Sa (μm) of the surface is 0.02 to 3.00, and providing a space where an air layer can exist between the particle layer and the surface.

The present invention is directed to provide a method of forming dimples comparatively simply on a surface of hard-brittle materials such as ceramics by post-processing. In the method, substantially spherical ejection particles having a median diameter d50 of from 1 &#x3bc;m to 20 &#x3bc;m are ejected together with a compressed gas at an ejection pressure of from 0.01 MPa to 0.7 MPa against a dimple formation region which is a region where dimples are to be formed on a surface of an article made from a hard-brittle material or a surface of an article having a surface coated with a coating layer of a hard-brittle material, or the like so as to form dimples on the surface of the hard-brittle material by plastic deformation without occurrences of breaks or cracks.

A surface treatment method is provided that is capable of raising the slidability of a ceramic surface at low cost using a comparatively simple method. Dimples are formed on a surface of a treatment region, this being a portion of a ceramic surface where surface treatment is to be performed, by ejecting substantially spherical ejection particles having a median diameter of from 1 &#x3bc;m to 20 &#x3bc;m, together with compressed gas at an ejection pressure of from 0.01 MPa to 0.7 MPa, so as to achieve a value of a fastest decay autocorrelation length of not less than 10. The dimples are formed so as to have a plan view profile with a ratio between a horizontal Feret diameter and a vertical Feret diameter of from 0.7 to 1.43. Thereby a ceramic surface with improved slidability can be obtained regardless of use or non-use of a lubricant.
