Title:
フェライト/マルテンサイト9~12%Cr鋼の表面処理方法
Document Type and Number:
Japanese Patent JP5455327
Kind Code:
B2
Abstract:
A method for the surface treatment of ferritic/martensitic 9-12% Cr steels for the purpose of achieving an improved oxidation behavior and increased resistance to solid particle erosion at application temperatures of above 500° C., in particular around 650° C., in steam includes, in a first step, a known shot peening of the surface of the steel with steel particles, and, subsequently, in a second step, shot peening with glass particles, optionally, in a following third step, the surface of the steel being smoothed. A subsequent additional heat treatment is unnecessary.
