There is growing interest in the use of compliant materials as an alternative to hard bearing materials such as polyethylene, metal and ceramics in artificial joints. Cushion form bearings based on polycarbonate-urethane (PCU) mimic the natural synovial joint more closely by promoting fluid-film lubrication. In the current study, we used a physiological simulator to evaluate the wear characteri...

Ti-6Al-4V alloy has been widely used in industrial fields. Electrical discharge machining (EDM) is a commonly technology for alloy. During EDM of alloy, the thermal and physical characteristics tool electrode have an important influence on processing characteristics. In order to study different materials brass electrode, copper tungsten were perform this paper, electrodes with V-groove array st...

Influence of initial surface roughness on friction and wear processes under fretting conditions was investigated experimentally. Rough surfaces (Ra=0.15-2.52 μm) were prepared on two materials: carbon alloy (AISI 1034) and titanium alloy (Ti-6Al-4V). Strong influence of initial surface roughness on friction and wear processes is reported for both tested materials. Lower coefficient of friction ...

The significant costs insert on mineral processes due to mill liner wear including the labor costs, price of material and shut down periods. Therefore, the study of this phenomenon is economically important to optimize the mill operating conditions and liner profile design to decrease the wear rate. There is no appropriate and applicable research on impact wear evaluation of mill liners. In the...

in this research, our attempt is to monitor tool wear through the chip formations, forces, and temperature of edge of drill while drilling in superalloy plate to optimizes effective parameters, which lead to facilitate machining process to, improved tool life, and enhance the productivity. in this study, inconel718 superalloy material, and cemented coated carbide tool was selected for investiga...

the glucose oxidase (gox) electrochemical sensors were used to detect a little amount of glucose. in this paper, the pure platinum plate (length of 5 cm and a width of 3 mm), the ag/agcl electrode and platinum electrode (diameter of 1 mm) were applied as a working electrode (w.e), reference electrode and auxiliary electrode sequential. factors measured, glucose concentration and ph is phosphate...

The purpose of this study was to develop a closed-loop machine vision system for wire electrical discharge machining (EDM) process control. Excessive wear leading breakage is the primary cause EDM failures. Such interruptions are undesirable because they affect cost efficiency, surface quality, and sustainability. developed monitors using an image-processing algorithm suggests parametric change...
