Abstract

Abstract: Metal Matrix Composites (MMCs) production is one of the major role in the industries, the Powder Metallurgy method is suitable for production of MMCs at correct proportional rate. Aim of this experimental work is prepare the Aluminium Metal Matrix Composites (AMMCs) by powder metallurgy route. Aluminium alloy AA7085 is selected for this experimental work due to their extreme mechanical properties. Strengthening of this aluminium alloy is carried out by addition of Titanium Diboride (TiB2) with different weight percentage. AMMCs are prepared through powder metallurgy route and the process parameters of the P/M are optimized with the aid of Taguchi approach. Parameters are selected for this experimental work is milling time (3 hrs, 4 hrs and 5 hrs), compaction pressure (200 MPa, 250 MPa and 300 MPa) and sintering temperature (550 °C, 600 °C and 650 °C). Minimum corrosion rate is obtained as 0.00092 mm/year, milling time is highly influenced in the corrosion rate analysis.
