- Abstract
Cu-boron nitride nanosheets (BNNSs) composite coating was fabricated by mechanical alloying and then cold spray. The microstructure, mechanical properties and tribological performance of the composite coating were investigated. The addition of BNNSs into Cu leads to a decrease in the deposition efficiency and microhardness of the coating. However, the introduction of BNNSs reduces the coefficient of friction evidently and improves the wear resistance significantly (by 34%) due to the sliding and lubricating effects of the BNNSs. Hence, the Cu-BNNSs composite coatings could be excellent candidates for low friction and high wear-resistance applications.
