Wear resistance of WCp/Duplex Stainless Steel metal matrix composite layers prepared by laser melt injection

This paper presents the development and characterization of aluminium alloy 6063 based metal matrix composite with varying combinations of fly ash and Borosilicate reinforcements. In the present work, the aluminium alloy 6063 (AA) is taken at a constant 84 vol% while the reinforcements Fly Ash (FA) and Borosilicate (B) are varied in the proportions of 2%, 4% 8%, 125 and 14%. Six samples were fabricated by stir casting and the mechanical properties were analyzed using tensile test, hardness test and wear test while the microstructure is analyzed by obtaining SEM and EDX images of the specimen. It is seen that both the reinforcements used in this study, increased the tensile and wear resistance of the alloy. The desirable mechanical and micro structural properties were found to be in the specimen with 84% AA, 14% FA and 2% B. The tensile strength of the aluminum alloy at this desirable combination is found to increase by 11.97%, ductility by 36.75% and the wear resistance by 62%. This metal matrix composite of AA6063 with fly ash and Borosilicate reinforcements can be used in automobile, aerospace and structural applications where wear resistance and tensile properties are mainly required.

Hybrid Metal Matrix Composites

In the present scenario aluminium is an useful metal due its admirable properties such as light weight, low cost and excellent thermal conductivity.In order to take advantages of these properties aluminium is being used to make the metal matrix composites for tribological application, In this present investigation effort has been made to assess the wear properties of Al–B4C–Gr metal matrix composite at various temperatures such as 323° K, 373° K and 423° K. Al–B4C–Gr Hybrid metal matrix composites were fabricated by stir casting technique. The influence of parameters like load, speed, distance and temperature on the wear rate was investigated. A plan of experiments, based on Taguchi model with L27 orthogonal array and analysis of variance was employed to investigate the influence of process parameters on the wear behaviour of these hybrid metal matrix composites. The wear resistance increased with increasing temperature, but wear resistance decreased at higher loads. It was observed that the abrasive wear is dominates while sliding as observed by SEM analysis of worn out specimens.

In the present study, metal matrix composite clads of nickel–alumina powder-based material have been produced on austenitic stainless steel (SS-304) substrate using microwave heating at 2.45 GHz frequency. A concept of hybrid heating was used to process metal matrix composite clads at exposure power level of 900 W. The exposure time for developing metal matrix composite clads was varied from 60 to 300 s. The clads of average thickness 0.6 mm were successfully developed at an optimized exposure time of 300 s. The microstructural analysis of microwave processed clads reveals the uniform dispersion of alumina powder particles inside nickel matrix. The developed clads were free from any type of interfacial cracks and were metallurgically bonded with SS-304 substrate. X-ray diffraction study confirmed the presence of alumina powder, FeNi3 and chromium carbide phases, which contributed to the increase in micro-hardness of developed clad. Clad micro-hardness was found to be four times that of austenitic stainless steel, which makes it suitable for anti-wear applications.
