摘要:
Thermally sprayed coatings made from carbides of metals having greater carbon affinity than Cr in the presence of free carbon, or thermally sprayed coatings made from carbides of metals having smaller carbon affinity than Cr are heat treated in a chromium halide containing atmosphere which also contains hydrogen gas, whereby activated metallic Cr is precipitated in a fine particulate form, which is allowed to act on the thermally sprayed coatings, whereupon a Cr₂₃C₆-form carbide is created not only on the coating surface but also in its interior, particularly within pores, to form a modified layer, thereby compositing the thermally sprayed coatings. Members coated with thermally sprayed Cr₃C₂, Cr₇C₂ coatings or thermally sprayed chromium carbide coatings further containing free carbon or carbides of metals having smaller carbon affinity than Cr are heat treated in a chromium halide generating atmosphere which also contains hydrogen gas, whereby activated metallic Cr is precipitated in a fine particulate form, which is allowed to act on the thermally sprayed coatings, whereupon a Cr₂₃C₆-form carbide is created not only on the coatings surface but also in its interior, particularly within pores, to form modified, thermally sprayed chromium carbide coatings.
