▎ 摘  要

NOVELTY - A silicon carbide granule enhanced iron-based composite material comprises 1.0-5.8 mass% aluminum, 3.5-7.5 mass% molybdenum, 1.0-3.5 mass% copper, 0.6 mass% tin, 10.0-22.6 mass% graphene, 2.4-4.8 mass% magnesium, 1.2-1.6 mass% silicon carbide, 1.0-1.5 mass% silicon, 0.05-0.15 mass% boron and rest iron. USE - Silicon carbide granule enhanced iron-based composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing silicon carbide granule enhanced iron-based composite material, which involves mixing copper, silicon and iron to obtain base layer, rest material as alloy layer, mixing alloy layer powder and base layer powder according to ratio of 1:2-4 to speed of 25-50 rpm for 30-80 minutes to obtain mixed material, sintering the mixed material at 500-600 degrees C for 30-60 minutes to obtain finished product.
