Surface Composites Preparation of AL5052 Reinforced with Al2O3 by Friction Stir Processing

“…It has developed as one of the advanced engineering materials having prospective application in numerous areas of automobile, nuclear, electronics and aerospace components. In the present scenario, to improve the surface properties of the materials several surface modification techniques are developed such as high energy laser melt treatment [1], plasma spraying [2], cast sintering [3] and casting route [4].…”

In Situ TiC/TiB2 Particulate Locally Reinforced Steel Matrix Composites Fabricated Via the SHS Reaction of Ni–Ti–B4C System

“…Recently, the combination of self‐propagating high‐temperature synthesis (SHS) and traditional casting routes provides an easy process to produce ceramic particulate reinforced steel matrix composites 1–15 . Among these composites, in situ ceramic particulate locally reinforced steel matrix composite may be one of the most promising composites which can be widely used in the practical application of excellent wear resistance and/or cutting performance with improved toughness such as pistons, brakes rotor, and mining machine, etc 4–10 .…”

Firstly, it can combine the advantages of the SHS reaction (such as low energy consumption, high time efficiency, and high product purity) 11–15 with the convenience of the casting process (such as easiness and high efficiency); on the other hand, it also can overcome the high porosity of SHS reaction products and the poor castability of the metal melt caused by the introduction of a high volume fraction of reinforcement.…”

Reaction synthesis of Fe–(Ti,V)C composites

“…Over the last decade, attempts to produce TiC and VC particles reinforced iron-base composites by in situ techniques have been intensified. Additionally, a novel processing technique, cast-sintering has emerged and is used to produce Fe-TiC and Fe-VC surface composites (Wang et al, 1999a(Wang et al, , 1999b(Wang et al, , 2000(Wang et al, , 2001(Wang et al, , 2004. These efforts have been driven by the fact that TiC and VC are extremely hard carbides; hence, the resultant composites are expected to possess high hardness and good wear resistance.…”
