Wear Studies on SiC and Fly Ash Reinforced Copper Based Composites by Grey Relational Analysis

Abstract

Copper base composites are extensively used in applications where high temperature and corrosive environment. In the present investigation a hybrid metal matrix composite is prepared in which copper is used as a matrix, SiC and Fly ash as reinforcements. The composite is produced by powder metallurgy technique. Dry sliding wear characteristics of the prepared composite specimes were studied by pin on disc setup and optimised result was found through grey relational analysis. Analysis of variance is used to investigate the significance of design parameters which affect the wear characteristic of the materials. The results showed that sliding velocity is having the significant effect than the other parameters.

Experimental and modeling studies on dry sliding wear behavior of Alumina reinforced AMC

“…The measured wear data was converted to S/N ratio for analysis purposes through Minitab-17 [33][34][35][36]. Smaller-the-better condition was adopted for wear loss [38][39][40]. The main effects plot for wear loss for SNR mean values as shown in figure 9.…”

Fabrication of Motorized Low Speed Double Cone Blender

“…Blending is critical step in powder metallurgy for obtaining the uniform distribution of particle reinforcement in metal matrix composite, to efficiently mix the different particle size materials for reduced porosity [2]. Manual blending often results in agglomeration of particles [3]. Blender are also used widely in the pharmaceutical industries [4].…”

Corrosion Examination on Copper based Composite Under Different Environmental Conditions

“…Copper based composites are used in various marine applications such as propellers, pump impellers and in components of missiles and torpedoes [20] where the corrosion resistance property plays a major role. Even though some studies on copper fly ash composite is available [21], [22], the effect of addition of fly ash on corrosive behaviour of copper fly ash is not yet reported to the best of our knowledge. In the present study copperfly ash composite with varying proportions of fly ash is prepared through P/M technique and studies were carried to find the corrosive behaviour of the composite under acidic and alkaline environmental conditions.…”
