Abstract:
1. A rolling bearing comprising an inner ring, an outer ring, and a plurality of rolling elements provided between a raceway surface of said inner ring and a raceway surface of said outer ring, said rolling bearing has a ceramic film formed on at least one surface selected from among an inner peripheral surface of said inner ring and a peripheral surface of said outer ring, wherein said inner ring and said outer ring comprise a metal material, wherein said ceramic film is formed by using an aerosol deposition method to form said ceramic film as a dense film that does not have pores that interconnect a surface of said ceramic film with said at least one surface selected from among an inner peripheral surface of said inner ring and a peripheral surface of said outer ring in order to prevent corrosive material from travelling through said ceramic film, and wherein said ceramic film is formed by using fine alumina particles of α alumina as a material of aerosol.
