Roller Burnishing of Particle Reinforced Aluminium Matrix Composites

Energy and resource efficient systems often demand the use of light-weight materials with a specific combination of properties. However, these requirements usually cannot be achieved with homogeneous materials. Consequently, composites enabling tailored properties gain more and more importance. A special kind of these materials is aluminium matrix composites (AMCs), which offer elevated strengt...

Influence of process and geometry parameters on the surface layer state after roller burnishing of IN718

Highly stressed components of modern aircraft engines, like fan and compressor blades, have to satisfy stringent requirements regarding durability and reliability. The induction of compressive residual stresses and strain hardening in the surface layer of these components has proven as a very promising method to significantly increase their fatigue resistance. The required surface layer propert...

Experimental study of Roller burnishing process on plain carrier of planetary type gear box

Burnishing is cold working process where hard roller are being pressed against irregular surface, so that surface finish and the micro hardness increases. In this study internal roller burnishing tool is used to burnish the drilled hole. Speed, feed, and number of passes have been varied using taguchi method to examine the surface finish and microhardness. Anova analysis is carried out. Surface...

Analysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061

Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
