Copper–Molybdenum Composite Coating with High Microhardness

This study aims to fabricate Cu–Mo electrocomposites using an acidic sulfate bath. The primary objective is to ensure a uniform distribution of molybdenum inclusions throughout the copper matrix, which is required to achieve maximum microhardness. Copper-based composite coatings with molybdenum powder incorporated into a galvanic matrix are produced. The particle size of the dispersed phase is chosen to achieve a 19.15% filler concentration. The resulting coatings are characterized by a significantly higher microhardness, measuring 58% greater than that of standard galvanic copper coatings.
