Method for surface-treating forging member

Abstract

An objective of the present invention is to provide an innovative method for surface-treating a forging member, the method exhibiting unprecedented operations and effects. The present invention is a method for surface-treating a forging member ( 1 ), wherein a slurry ( 4 ) comprising a mixture of a liquid ( 2 ) and an abrasive ( 3 ) is mixed with pressurized air and sprayed on a surface ( 1 a ) of the forging member ( 1 ), and innumerable recesses ( 5 ) measuring 0.5-2.00 μm in depth and 75-150 μm in opening width are provided on the surface ( 1 a ) of the forging member ( 1 ).

1 . A method for surface-treating a forging member, characterized in that a slurry comprising a mixture of a liquid and an abrasive is mixed with pressurized air and sprayed on a surface of the forging member, and innumerable recesses measuring 0.5-2.00 μm in depth and 75-150 μm in opening width are provided on the surface of the forging member. 
     
     
         2 . The method for surface-treating a forging member according to  claim 1 , characterized in that the forging member is made from chromium-molybdenum steel. 
     
     
         3 . The method for surface-treating a forging member according to  claim 1 , characterized in that a stainless-steel abrasive having an average particle diameter of approximately 150 μm is adopted as the abrasive. 
     
     
         4 . The method for surface-treating a forging member according to  claim 2 , characterized in that a stainless-steel abrasive having an average particle diameter of approximately 150 μm is adopted as the abrasive.
