Road maintenance and cleaning in winter are performed with ploughshares. Due to the fact that layer of snow ice is removed from road surface contains various hard impurities, ploughshares exposed high intensity abrasive wear. This article deals resistance wear originally used ploughshare materials were designed as a suitable modification increase its service life. The chemical composition manuf...

The ion nitriding behavior of AISI 316L austenite stainless steel was investigated at different times (2 h, 4 and 9 h) temperatures (450 °C, 500 550 °C). structural characterization has been assessed by several considerations which can be listed: (i) the evaluation phase distribution through Rietveld analysis X-ray diffraction patterns accompanying peak fitting process, (ii) hardness profile re...

Hinge-based Ankle Foot Orthosis (HAFO) is one of the most common non-surgical solutions for the foot drop. In conventional HAFOs, the ankle joint is almost locked, and plantar flexion is restricted due to the high stiffness of the hinge mechanism. This often leads to a rigid walking gate cycle, poor muscle activity, and muscle atrophy. Since the ankle torque-angle loop has a non-linear profile,...

Heat treatments were carried out at 350, 450, 550 and 650°C on WC-10Co4Cr coatings deposited by High-Velocity Oxy-Fuel (HVOF) onto AISI 420 stainless steel substrate in order to study their influence the abrasive wear resistance of coatings. The thickness microhardness measured while microstructure was analysed with aid OM, SEM XRD techniques. X-ray diffraction results revealed presence W2C pha...

In pyrolysis technology there are various geometric factors that affect the results of pyrolysis, one which is connecting pipe between reactor and condenser. this study, simulations were carried out with simscale software to analyze temperature, pressure gas velocity in as length increases. The material used stainless steel AISI 304. This research begins by determining dimensions materials pipe...

The purpose of this work was to evaluate the microstructural alterations associated aging thermal treatments performed at 450, 475, 800 and 850°C, for 1, 3 12h, besides evaluating influence precipitation alpha line phase on corrosion resistance. samples were characterized by scanning electron microscopy, energy dispersion spectrometry, X-ray diffraction, feritscope, hardness, microhardness, in ...

Copper is a useful material to show the high electric conductivity, heat conductivity and, antibacterial and virus inactivating effects. A blue diode laser with wavelength of 450 nm one suitable lasers for copper processing. High intensity precision materials processing technology using were developed. power 200 W was applied selective melting additive manufacturing. coating on stainless steel ...

Concrete-Filled Steel Tube (CFST) columns need to be reliably analyzed and estimated under axial compression. This research contributes solving the above problem by using an integrated Ansys Workbench application, DesignXplorer. approach is convenient for academics industry in CFST column design because proposed compressive strength formulas will established parameters’ properties. Correlation ...

Abstract The microstructure of a low alloy medium carbon bainitic steel, austempered in the temperature range 275 °C to 450 has been investigated by detailed electron backscatter diffraction and variant pairing analysis. It is observed that tendency two distinct changes with varying temperature. At V1-V6 most frequent, whereas V1-V2 frequent at intermediate highest temperature, V1-V4 dominates....
