Abstract
Provided are an inorganic member and a method for manufacturing an inorganic member. The inorganic member is configured so that a fine irregularities can be formed on the surface thereof with a simple procedure, and by controlling the shape of the irregularities, realize excellent durability and low wettability with respect to water without forming (depositing) an organic fluorine-based coating film. At least a part of a main surface (surface), in which a skewness of the fine irregularities is −0.1 or less. The fine irregularities are formed by performing the wet blast treatment.
Claims13
An inorganic member comprising fine irregularities on at least a part of a surface of the inorganic member,
- wherein a skewness Ssk of the fine irregularities is −0.1 or less, and
- wherein a mean width RSm of roughness profile elements of the fine irregularities is 30 nm or more and 750 nm or less.
An inorganic member comprising fine irregularities on at least a part of a surface of the inorganic member,
- wherein a skewness Ssk of the fine irregularities is-0.1 or less, and
- wherein a ratio (Rc/RSm) of a mean height Rc of roughness profile elements to the mean width RSm of roughness profile elements of the fine irregularities is 0.02 or more and 1.00 or less.
An inorganic member comprising fine irregularities on at least a part of a surface of the inorganic member,
- wherein a ratio (Rc/RSm) of a mean height Rc of roughness profile elements to a mean width RSm of roughness profile elements of the fine irregularities is 0.03 or more and 1.00 or less.
