When applying copper coating and surface treatment by diffusion infiltration (hereinafter referred to as "diffusion infiltration"), the surface to be treated is coated with chlorinated steel and the product is passed through a heating furnace. When the product is charged and heated at 400 to 500°C for several tens of minutes by heating in an atmosphere or by transferring heat on a hot plate equipped with a heater, the entire product is uniformly heated and copper diffusion and penetration treatment is performed. The cavities or gas inside the product may appear as blisters on the surface of the diamond 1, and in addition, the product may be so defective that further surface treatment cannot be performed.

Part of 1 surface 5 of aluminum tie-cast product 4 I
After applying copper chloride to an area of Qm x 10 fl, place the coated surface 20 to 30 degrees apart within the irradiation area of the 11.6 wall/c-infrared lamp 2 of the near-infrared heating device 1. 6. Then, turn on the power switches of the blower 8 and the lamp 2, and put the applied surface 5 on top.
By irradiating near infrared rays for 90 to 120 seconds,
The coated surface 5 has a 400 to 500
C. to complete the reaction. In this case, the part of the tie-cast product 4 outside the surface layer of the coated surface 5 is locally absorbed by the infrared rays - and furthermore, since it is for a short time, there is no time for heat conduction to occur, so that the temperature reaches the reaction temperature. The die-cast product 4 is not heated, so internal defects in the die-cast product 4 are not caused.3- The base material does not bulge. If the coated surface 5 does not cover the entire surface of the product 4, the above-mentioned absorption can be further improved and the time required to raise the temperature to the reaction temperature can be shortened.
