Abstract
A method for removing a surface layer from a solidified body of metal at an elevated temperature to remove surface defects therefrom. The method comprises providing a solidified body having a surface wherein the body can have a temperature greater than 200.degree. F. and below the solidus temperature of the metal. The metal surface is contacted with an abrasive material having a particle size in the range of 6 to 300 grit (U.S. Sieve Series). The abrasive material is applied at a flux sufficient to remove a surface layer from the body, the layer having a thickness in the range of 10 to 300 .mu.m to provide a surface substantially free of said surface defects.
