THE EFFECT OF VARIOUS PARAMETERS ON DRY SLIDING WEAR BEHAVIOR AND SUBSURFACE OF AGED HYBRID METAL MATRIX COMPOSITES USING TAGUCHI TECHNIQUE
The effects of applied load, sliding speed and sliding distance on the dry sliding wear behavior of aged Al-SiCp-Gr composites were investigated. The specimen were fabricated by stir-casting technique. The pin-on-disc wear testing machine was used to investigate the wear rate by design of experiments based on L27 using Taguchi technique. Sliding distance was the most important variable that inf...
متن کاملStudy on the Surface Integrity of a Thin-Walled Aluminum Alloy Structure after a Bilateral Slid Rolling Process
For studying the influence of a bilateral slid rolling process (BSRP) on the surface integrity of a thin-walled aluminum alloy structure, and revealing the generation mechanism of residual stresses, a self-designed BSRP appliance was used to conduct rolling experiments. With the aid of a surface optical profiler, an X-ray stress analyzer, and a scanning electron microscope (SEM), the difference...
متن کاملThe Behavior of Indentation Marks in Rolling–Sliding Elastohydrodynamically Lubricated Contacts
Indentation marks in rolling–sliding contacts are known to increase the risk of failures in heavily loaded elastohydrodynamically lubricated contacts found in machine elements, like gears and rolling bearings. In this article, literature is discussed showing the different hypotheses available to explain the interaction of sliding with the indentation marks, in both gears and rolling bearings. W...
متن کاملResidual stress field of HIPed silicon nitride rolling elements
The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3kgf/ball to 10.87kgf/ball and four kinds of commercially finished 1⁄2′′ (12.7mm) HIPed Si3N4 balls before, during and after RCF tests were investigated. The experimental results showed that in the finishing process of HIPed...
متن کاملRolling contact fatigue in martensitic 100Cr6: subsurface hardening and crack formation
Rolling contact fatigue tests on 100Cr6 steel were carried out with a ballon-rod tester. Microstructural damage was manifested by gradual hardness changes under the subsurface, and microcracks formed adjacent to inclusions; both being evidence of plastic deformation. The hardness increase appears to be due to the development of residual stress, while the microcracks form as a result of the conc...
