    • PROBLEM TO BE SOLVED: To provide an adhesion evaluation method for a die-cast mold release agent enabling appropriate evaluation of an adhering state of the mold release agent applied to a molding surface of a mold.SOLUTION: An adhesion evaluation method for a die-cast mold release agent includes: an irradiation step of irradiating a coated surface that is formed by spray coating of a coating fluid obtained by dissolving or dispersing the mold release agent and a fluorescent agent in water on a heated molding surface of a mold, with excitation light that corresponds to the fluorescent agent; and a measurement step of receiving fluorescence emitted from the fluorescent agent to measure fluorescence intensity. The measurement step is an intensity distribution measurement step of continuously measuring fluorescence intensity in a specific region of the coated surface to obtain intensity distribution. The adhesion evaluation method further includes an identification step of identifying an index value indexing an adhesion state of the mold release agent in the specific region on the basis of the intensity distribution. Using the index value enables appropriate evaluation of the adhesion state of the mold release agent and thus releasability during die casting even if coating unevenness of the mold release agent is large.

The coated member expresses the consistent heat resistance by the synergetic action of these factors. The DLC-Si film has preferably a gradient composition in which the Si concentration on the surface side is 8-30 atom%, and the Si concentration on the base material side is gradually increased.
