Apr 02, 2019 · An innovation for microstructural modification and mechanical improvement of TiAl alloy via electric current application and the uniformity of the scale is of stainless steel by electric Anodizing World:Using slow Square Pulse Anodizing for This weeks posts will be about Pulse Anodizing. The two main reasons for using pulses during the hard anodizing process claims that it is possible to increase wear resistance and corrosion resistance of the formed oxide layer. Another advantage shown is an improvement in thickness uniformity

Automotive Body Forming and Joining Technology

For example, ultrasonic assisted manufacturing reduces the flow stress of materials and improves contact conditions, surface quality and microstructure uniformity. Pulsed current assisted manufacturing technology plays an important role in increasing the thermal deformation temperature range of difficult-to-deform materials, improving the machinability of parts. Comparative study on structure, corrosion and hardness of Feb 05, 2012 · The pulse 40% duty cycle at lower pulse frequencies enhancement of migration of ions increases the nucleation rate, uniformity of deposit , and deposition rate, and hence current efficiency is increased. Higher current efficiency and thickness of deposits is obtained from electrolyte-4 than that of electrolyte-1, 2, and 3. Dry Sliding Friction and Wear Behaviour of an Electron Sep 20, 2011 · Machined surfaces of an A390 alloy were subjected to five pulsed electron doses with an applied cathode potential between 16.5 and 36 kV. It was found that increasing beam accelerating voltages led to an initial decrease (1.4 m R a ) but subsequent increase (4.0 m R a ) in average surface roughness values associated with surface crater formation due to sub-surface melting and eruption.

Effect of adhesive on laser-arc hybrid welding of aluminum

Jul 14, 2020 · Aluminum alloy 6061 and high-strength steel Q460 were joined by laser-arc-adhesive hybrid welding technology successfully. A Cu alloy interlayer was added between Al alloy and high-strength steel. The effect of the adhesive on laser-arc-adhesive hybrid welding of Al alloy to high-strength steel was discussed. The optical microscope, scanning electron microscope and electron Effect of magnetic field on residual stresses in NiAlRe This article reports that the uniformity of the alloy steel 20Cr2Ni4A is improved by using pulsed magnetic treatment. The pulsed magnetic field with 1, 4 and 9T was applied on the tempered samples. Enhanced mechanical and corrosion protection properties of Dec 15, 2020 · Pulse electrodeposition is a technique of particular interest, which offers promising advantages such as ease of processing, compositional control, uniformity in structure, and grain refinement. In the present study, NiP-ZrO 2 nanocomposite coatings containing various concentrations of ZrO 2 nanoparticles (ZONPs) were deposited on low alloy steel (30CrMnSi) through pulse
