Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023 In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Advanced Science, EarlyView.Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

Formation of Fe-6.5wt%Si High Silicon Steel by Double Glow Plasma Surface Metallurgy Technology [PDF]
arXivHigh silicon steel with 6.5% silicon content is the best because of its excellent magnetic properties, such as high saturation magnetization, high resistivity, low iron loss and near zero magnetostriction. High silicon steel can greatly save energy, and reduce the weight and size of electrical appliances.

, 2020 Gender is frequently invoked as a core explanatory factor for many aspects of past African metallurgy, including conceptualizations of the technological process by its practitioners, the organization of—and participation in—metallurgical production activity, and the acquisition of power and wealth that is associated with it. If a study of technology is
