摘要: Abstract Dry sliding wear of an AA 6061 alloy reinforced with both modified SiC particles and metal coated carbon fibres has been studied. were used to increase the hardness composite while short are supposed act as a solid lubricant. silica layer deposited through sol–gel procedure processability enhance particle–matrix interfacial resistance. The metallic coatings on made copper or nickel phosphorus which was electroless process. favoured wetting during processing then dissolved in aluminium matrix forming intermetallic compounds that increased its hardness. Wear behaviour 6061–20%SiC 6061–20%SiC–2%C compared composites same reinforcement content but using fibres. influence modification because incorporation reinforcements had mild investigated. resistance when added secondary used.
