METHOD FOR FINISHING SPRAY COATED SURFACE, AND WORK TOOL

摘要

In a method for a finishing work of a spray-coated surface, an inner surface of an cylindrical hollow member is roughened by forming helical groove thereon, a thermal spray coating is formed on the inner surface that is roughened, and a finishing work is carried out by cutting the thermal spray coating along a helix of the groove by use of a cutting tool. According to the method for a finishing work, a finishing work of a thermal spray coating that has hardness ununiformity can be carried out efficiently.
