The objective of this research work is to observe the behaviour of mechanical properties in accordance with the stirring speed during casting process. The hardness, tensile strength, wear behaviour

Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties

Jan 01, 2020 Prabu et al. studied the influence of stirring speed and stirring time of silicon carbide (SiC) particles reinforced in A384 aluminium alloy processed by stir casting process. 10 wt% of SiC with average particle size of 60 μm was added to the melt and stirred with a speed of 500–700 rpm. Duration of stirring was varied from 5 to 15 min

Xu et al. analysed wear mechanism of three grinding wheels (made of Al 2O 3, SiC and CBN, respectively) in Ti6Al4V titanium alloy grinding process [10]. SEM micro-observations of the active grinding wheel surface indicated that adhering Ti6Al4V material can be seen on SiC grits when the machining temperature is raised up to 1000 C

crushed, graded to various sizes. Silicon carbide is very hard ( but less harder than boron carbide). It has high heat resistance and excellent cutting properties. There are two types of silicon carbide tools are available, namely black and green. The black silicon carbide is of lower quality and contains about 95% SiC. Green silicon carbide is

Aug 01, 2008 Wear resistance of Al-4 wt% Mg alloy improves significantly after addition of copper and/or silicon carbide particles. 2. The wear rate of the matrix alloy and the composites almost increased linearly with increasing the sliding distance. But wear rates of the P/M Al–Mg–Cu–SiC components were much smaller than that of Al–Mg–Cu

Comparison of SiC andAl 2 O 3 (i) Al 2 O 3 is more tough than SiC but its hardness is less. Al 2 O 3 is, therefore very suitable for grinding materials of high tensile strength (2700 kgf/cm 2). If Al 2 O 3 be used with material of low tensile strength, then resistance offered by the material on grinding

May 25, 2015 Copper-based composites reinforced with 15–35 wt.% SiC were produced by mechanical alloying in a planetary mill and hot pressing.Grinded copper chips less than 5000 μm in size and 10 μm SiC particles were used as initial materials.Optical and scanning electron microscopes were used for microstructural analysis
