<p>Described herein is an article plated with boron carbide in a nickel-phosphorus matrix, obtained by means of a plating process comprising the following steps: a) preparation of an electrolytic bath comprising two or more nickel salts, at least one complexing agent, at least one phosphorus salt, and, in addition, an anti-tensioning agent and boron carbide in the form of powder; b) electroplating of the article in said electrolytic bath at a temperature ranging from 40 DEG C to 70 DEG C, with a current density ranging from 1 to 10 A/dm<2> and finally c) heat treatment of the product thus plated. The aforesaid plating is used for any article that requires a type of plating which presents high resistance to wear, and in particular for cylinders for the production of corrugated cardboard.</p> |
