Automotive gears are facing stringent requirements regarding weight and functional surfaces, especially in view of the electric powertrain. To achieve these demands, powder metallurgy need to be finished using grinding, certain cases, mechano-chemical treatments. With regards latter, five different triboconditioning strategies based on vibratory tub finishing and/or centrifugal barrel were cons...

The turning process of titanium alloy material will affect the surface structure and lead to a change in its service life. In this paper, fatigue behavior TC17 sample was studied through bending test. life variation rule under action thermal coupling then discussed. This revealed fracture mechanism TC17; cracks originated from source region, transient fault region ductile fracture. mathematical...

Abstract In this study, the effect of cutting conditions on surface integrity was investigated in micromilling magnesium alloy (AZ91). Microtool diameter, speed, feed rate, and depth cut parameters are used. These variables were at three different levels with Taguchi L 9 experimental design method. The least-best objective function As a result experiments, roughness values obtained. It has been...
