METHOD AND DEVICE FOR PRODUCING SILVER-CONTAINING LAYER, SILVER-CONTAINING LAYER, AND SLIDING CONTACT MATERIAL USING SILVER-CONTAINING LAYER

摘要

In a cladding composite material obtained by coating the surface of a base material with an Ag-containing layer, it is difficult to make the size of fine Ag-containing particles which form the structure of the Ag-containing layer uniform in the thickness direction. A vaporization source (15) which contains Ag is irradiated by a high-energy laser beam 17 having a spot diameter for causing vaporization as fine particles which contain Ag from the vaporization source (15) which contains Ag, the fine particles which contain Ag are vaporized, and the fine particles which contain Ag which were obtained by vaporization are ejected as jet to a base material 33 under a high vacuum atmosphere to make than physically deposit on the base material 33 thereby Ag-containing layer is formed on the base material 33.
