<p>A method of manufacturing a sliding bearing comprising providing a substrate 1 as a cathode in an electrolyte within which a hard particulate is suspended, and depositing a composite layer 5 of hard particulate embedded in a metallic matrix by applying a repeating cycle of bias pulses to the substrate. The cycle comprises a high cathodic bias portion and a further bias portion selected from the group consisting of a low cathodic bias portion, a zero cathodic bias portion and an anodic bias portion, and a sliding bearing manufactured by such a method. The electrolyte may be agitated to maintain the particulate in suspension. The metallic matyrix may be tin (Sn). The hard particulate may be TiCN, SiC, NbC, Si3N4, Al2O3, TiN or B4C.</p> |
