SINTERING METHOD FOR HERD ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a sintering method for a hard alloy, which prevents adjacent pressed bodies from sintering each other when sintered. SOLUTION: The sintering method for the hard alloy, which sinters pressed bodies 1 of the hard alloy material mounted on a sintering tray 2, includes setting a material 3 containing (C6 H10 O5 )n onto at least one part of the surface of the press body 1 before sintering it. The material 3 containing (C6 H10 O5 )n placed between the press bodies 1 works as a release agent to prevent the pressed bodies 1 coupled each other when sintered.
