摘要： 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 A1, A2 depending on peripheral speed or treatment difficulty in surface treatment of the rotary member 1; 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.

摘要： The Ni-Cr-Mo-V-C based alloy can be suitably used as a member which is required to have corrosion resistance and abrasion resistance. The alloy essentially consists of, by weight: 23~50% Cr; 7~20% V; C not less than 1.6% and not more than (0.236V%+2)%; Mo not more than 40% and not less than any of (11-0.1*Cr%) and (125-4*Cr%)%; and the balance of Ni and inevitable impurities. The total amount of Cr, V, and Mo is not more than 90%.
