    Abrasive jet processing of glass, a brittle material, typically induces surface roughening via material removal in brittle manner. In precision cutting and grinding, decreasing the depth of cut results in brittle-ductile transition in the material removal mechanism, promoting excellent surface quality. This study attempted fine particle peening as an abrasive jet surface processing method via ductile manner for higher precision surface texture fabrication of glass than the conventional peening technique. Collision dents observed on the peened glass surface under shallow peening angles suggested that plastic flow of glass occurred when the material was peened. A precise surface texture 0.1μm in size was fabricated on the glass surface under appropriate peening conditions. Ductile-mode processing of the glass by fine particle peening was implied because the depth of the dents did not deviate from the critical depth of cut determined with nanoscratching. The advantages of the fabricated precise texture with a scale of several hundred nanometers were explored by powder adhesion testing of the textured glass specimens. The results showed that the textured glass had better antifouling performance against powder adhesion than unpeened control samples with a smooth surface. Good antifouling performance was obtained if the powder grains were greater than or equal in size to the spacing of peaks of the texture.
