PURPOSE:To easily mirror-finish the surface of stainless steel by lapping the surface with a lapping fluid consisting of an aq. nitric acid soln., abrasive grains and a surfactant. CONSTITUTION:When the surface of stainless steel is mirror-finished by lapping, a lapping fluid contg. abrasive grains of Al2O3, Cr2O3 or SiC having 0.3-0.5mum grain size and a cationic surfactant at <=0.1wt.% concn. in an aq. HNO3 soln. having 1-2wt.% concn. is used. The surface of the stainless steel can be mirror- finished in a relatively short time. |
