Mold and its manufacturing method |
| abstract |
It is possible to provide a mold having good adhesion resistance and smoothness and a method for producing the same. A mold comprising a composite material comprising a hard phase and a metal phase, wherein the mold has a reinforcing layer composed of a hard phase on a work surface, the work surface having an arithmetic mean roughness Ra? 0.1 mu m, Is satisfied. The present invention also provides a method of manufacturing a mold made of a composite material including a hard phase and a metal phase, the method comprising: a shape processing step of processing a surface of a metal mold composed of the composite material and adjusting Ra to 0.1 mu m; And a surface modification step of etching the surface of the mold adjusted to Ra < RTI ID = 0.0 > l0 mu m < / RTI > and removing a metal phase in the vicinity of the surface. |
