Abstract
The invention discloses a high-strength abrasion-resistant powder metallurgy composite material and a preparation method thereof. Basic alloy blank powder is mixed evenly through a mechanical ball mill to form evenly mixed alloy powder to obtain basic alloy blank powder. The obtained basic alloy blank powder and carbon nano tubes are mixed and stirred according to the volume ratio of 200:1-20:1, and mixed powder is pasty, can flow in a vessel and is stirred by a stirrer to form even blank powder containing the nano tubes. The obtained blank powder and diamond particles are mixed and stirred according to the volume ratio of 19:1-3:2 to form an evenly mixed powder material embedded with diamond. The obtained powder material is filled in a graphite jig, and a carbon nano tube fiber strengthened diamond composite material is obtained through a hot-press sintering method or a pressureless impregnation sintering method. The carbon nano tube fiber strengthened diamond composite material is good in comprehensive performance, the blank hardness and the integral strength are obviously improved, diamond embedding capacity of blanks is enhanced, and the abrasion resistance is improved.
