Wear by slurry abrasion is a apparent problem in engineering components undergoing to specific flow. The existence of the components under slurry abrasive wear situations is largely decided by operating conditions and the materials properties. Aluminium alloys are extensively used for abrasion resistant applications. Our research is on "slurry abrasion response of die casting aluminium alloy (LM-13) under a wide range of experimental conditions". The response data is generated using methodical

... nd simultaneous variation of test parameters. The experiments were performed using silica sand slurry with different slurry concentration under different wheel hardness and load. The wear weight loss showed an increasing tendency with the increase of test parameters. Aluminium alloys, by virtue of their exceptional combination of properties, continue to evolve as direct replacements for steels. Though, the wider use of aluminium and its alloys is frequently impeded by their reputation for poor tribological behaviour. The present research mainly focuses on simple engineering scenario where comparative tribological behavior of surface engineered LM-13 in abrasive slurry has been evaluated to identify treatments capable of improving its wear behavior. LITERATURE REVIEW Aluminium-silicon alloy and aluminium based metal matrix composites (MMCs) holding hard particles which exhibit better operating performance and resistance to wear. Generaly during the industrial processes, abrasive slurries are moved by rotating impellers. When these elements are fabricated from metal matrix composites materials offer greater abrasive resistance and consequently a extended service life. Composites materials are usually described by having hardness greater than abrasive particles and because of reinforcement these materials also having high fracture toughness which results in high abrasive wear resistance [R.L. Deuis, C. Subramanian, J.M. Yellup ]. Due to exceptional blend of properties the titanium alloys are continue to advance as unswerving substitutes for steels in production systems to meet the tough offshore application situations. However, titanium and its alloys is also having character of poor tribological behavior. Therefore its become imperative to evaluate relative tribological performance of surface engineered Ti6Al4VELI in abrasive slurry to spot treatments capable of improving its wear performance. Sliding wear tests were done using a block-on-wheel test model in abrasive mud slurry to simulate potential application conditions. [H. Dong, A. Bloyce, T. Bell]. The wear character of the composite were studied by conducting abrasive wear test, and slurry erosive test. The abrasive wear performance of the metal matrix composites (MMCs) were examined by varying parameters. Dry Sand Rubber Wheel Abrasive Wear testing machine was used to examine abrasive wear performance.The results show that the wear resistance of TiB2-reinforced material enhanced with increase in TiB2 content. By and large results reveal that TiB2
