Titanium alloys are widely used in aerospace, the military industry, electronics, automotive fields, etc., due to their excellent properties such as low density, high strength, high-temperature resistance, and corrosion resistance. Many components need be finished precisely after being cut these applications. In order achieve high-quality high-efficiency finishing of titanium alloys, ultrasonic...

The suspension parameters are vital in the suspension-type abrasive water jet (AWJ) machining of several engineering materials, more so difficult-to-cut because it significantly influences stability and sedimentation behaviour mixture particle acceleration into AWJs. AWJs improved by using polymer additives. Hence, is necessary to study effect (abrasive concentrations) on stability. In this dir...

This study proposed a new magnetic abrasive finishing (MAF) method, in which 6-axis robot with machining tool was used to polish the inner surfaces of curved tubes. We have also developed jig, can be fixed at front robot, rotating freely and suitable for polishing In this study, we focused on investigating parameters initial stage precision stage. Based characteristics parameters, multi-stage M...

The catchment (bedrock and soil) sediments of lake Bol?t?u, Romania were studied by high resolution multi-methodological investigations to characterize paleoenvironmental formation conditions. Particle size analyses, optical cathodoluminescence microscopy, FTIR-ATR Raman spectroscopy, X-ray powder diffraction, XRF applied for microtextural, chemical, micro-mineralogical embedded organic materia...

Abrasive wear resulting from the microclastic rock is a common failure phenomenon in drilling environment that often limits sealing ability and service life of seals. In this study, friction process fluoro rubber (FKM) seals against 304 stainless steel (SS304) after one single entry SiO2 abrasives were investigated. The influence changes particle state on coefficient evolution, loss morphologie...

This paper presents a rage of variable machining factors which influence substantially friction directly or by the abrasive media wear developed in cutting zone. Abrasive flow is method surfaces complex holes and curved surface. In case traditional stream treatment methods (AFM) it difficult to obtain uniform roughness radial decomposition during polishing complicated openings, results from une...

in this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. this mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (maf) process. a permanent magnet which is mounted on a horn has been used as the processing tool. this polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. ultrasoni...
