Abstract
The invention provides a method for performing abrasion resistant surface treatment on a surface of a rotary member. The abrasion resistant surface treatment method is characterized by including steps of: dividing the surface of the rotary member into a plurality of areas A, Adepending on peripheral speed or treatment difficulty in surface treatment of the rotary member; spraying an abrasion resistant material on a surface of a first area where the peripheral speed is the highest, or the treatment difficulty is low, by a high speed flame spraying method; and spraying an abrasion resistant material on a surface of the second area with high treatment difficulty, by an arc spraying method.
