This paper introduces an experimental technique to investigate dynamic friction characteristics of sliding interfaces at normal pressures up to 125 MPa, slip speeds up to 15 m/s and slip distances of approximately 10 mm. This new apparatus involves a novel modification of the conventional torsional Kolsky bar apparatus employed extensively in the past to investigate high-strain-rate behavior of...

Aluminum alloys 7075 (Al 7075) are widely used for various industrial components in which machining operations often conducted during their manufacturing process. However, the could introduce defects on machined surfaces of will be carried over and may lead to either issues subsequent fabrication process or failure products' service life. This study investigates surface's Al underwent drilling ...

This study investigates the mechanical properties and wear behavior of Al 7075/Al2O3/SiCNP composites. The hybrid composites are manufactured using stir casting technique. In this work, 7075 alloy is reinforced with five different weight fractions Al2O3 a constant SiCNp, an average particle size 50 nm. aluminum metal matrix examined through surface morphology X-ray diffraction (XRD) patterns to...

Electric discharge drill machine (EDDM) is a spark erosion process to produce micro-holes in conductive materials. This process is widely used in aerospace, medical, dental and automobile industries. As for the performance evaluation of the electric discharge drilling machine, it is very necessary to study the process parameters of machine tool. In this research paper, a brass rod 2 mm diameter...
