The high corrosion resistance of the shiny side surface was attributed to the high protectiveness of the passive film and the structural homogeneity of the alloy.
Although reactive elements are capable of eliminating interfacial S segregation, they do not stop such segregation to alloy surfaces.
This paper demonstrates how the sintering of bronze-bonded grinding wheels influences their bond properties and the resulting grinding behavior.
Superabrasive grinding wheels are believed to be superior over conventional wheels, which can improve the surface integrity of the ground component.
Despite the advantages achieved with structured wheels, a higher wear of the structured wheels is a disadvantage associated with the structuring of grinding wheels.
Experimental results indicated that laser modified grinding wheels are comparable in performance to conventionally cleaned and dressed grinding wheels.
Additionally, for steels, CBN wheels are the most suitable whenever high superficial temperatures must be avoided since alumina wheels produce temperatures substantially higher.

What are the ergonomic considerations when designing a rotating working table?
4 answers
When designing a rotating working table, several ergonomic considerations should be taken into account. These considerations include facilitating rotation in two directions for ease of use by workers, ensuring smooth rotation under high loads to prevent abnormal sounds or shakes, thus improving user experience and prolonging service life, providing adjustable positioning blocks and pressing devices for convenient and secure workpiece fixation, and incorporating features like push-and-pull rods and chamber regulators to enhance precision and avoid grinding inaccuracies. Additionally, the design should include features like multiple pipelines for oil supply to reduce running resistance during rotation and maintain rotary accuracy. By addressing these ergonomic factors, a rotating working table can offer improved usability, efficiency, and safety for workers.
Does conductivity increase or decrease with dissolved oxygen?
5 answers
Conductivity tends to increase with dissolved oxygen levels. Research indicates that in the presence of higher dissolved oxygen concentrations, such as 9 mg L−1, the conductivity of water increases due to the formation of dissolved ozone and hydrogen peroxide, leading to higher conductivity levels. Additionally, a study on the effect of dissolved oxygen on the oxidation reaction of anodes in microbial fuel cells found that the current output decreased by 7% with the impact of dissolved oxygen, suggesting a correlation between dissolved oxygen and conductivity changes. Furthermore, the corrosion behavior of X80 pipeline steel in simulated soil solutions showed that as the dissolved oxygen concentration decreased, the corrosion current density reduced significantly, indicating a decrease in conductivity with lower dissolved oxygen levels.
Why magnetostriction reach zero at frequency resonance?
5 answers
The phenomenon of magnetostriction reaching zero at frequency resonance occurs due to the unique characteristics of the materials and their interactions with external fields. Research has shown that in certain magnets, the resonance frequency follows a universal power law, where the critical field at which the resonance frequency is zero plays a crucial role. Additionally, investigations into ferromagnetic steel wire-polymer composites have revealed that the magnetostriction behavior is influenced by the volume fractions of steel wires, with a resonance observed at specific frequencies. Furthermore, studies on high-entropy alloys have identified compositions that exhibit zero magnetostriction alongside excellent magnetic softness, emphasizing the role of material composition in achieving this phenomenon. These findings collectively contribute to understanding why magnetostriction can reach zero at frequency resonance in various magnetic systems.
