    Abstract Superhydrophobic coatings have attracted a lot of attention due to their excellent self-cleaning and anti-fouling capabilities. However, the preparation processes for several superhydrophobic coatings are intricate and expensive, which restricts their usefulness. In this work, we present a straightforward technique for creating durable superhydrophobic coatings that can be applied to a variety of substrates. The addition of C9 petroleum resin to a styrene-butadiene-styrene (SBS) solution lengthens the SBS backbone and undergoes a cross-linking reaction to form a dense spatial cross-linked structure, improving the storage stability, viscosity, and aging resistance of the SBS. The combined solution functions as a more stable and effective adhesive. Using a two-step spraying technique, the hydrophobic silica (SiO

    Abstract The rapid growth in digital design and manufacturing processes brings with it some work-flow challenges. While the various existing products provide an ideal solution to most of the steps in the process, more dedicated and integrated systems are sometimes required; raising the question of how best to handle the incoming data and orders, automate the design and possibly the engineering, make robust plans, manage the process and data and deliver quality goods.

    Abstract Research on the conductivity and corrosion resistance of stainless steel bipolar plates in a proton exchange membrane fuel cell (PEMFC) is commonly performed in a normal-temperature environment (about 20 °C). However, these fuel cells must function in low-temperature environments (lower than 0 °C) in some conditions, such as in vehicle fuel cells and in portable power supplies that operate during the winter in northern China. Stainless steel bipolar plates have higher requirements in terms of their hydrophobic and anti-icing properties, in addition to needing high conductivity and corrosion resistance. In this study, carbon nanotubes (CNTs) are grown on the surface of 304 stainless steel (304 SS) without a catalyst coating by plasma-enhanced chemical vapor deposition (PECVD), which is a simple and cheap method that allows stainless steel to be used as bipolar plates in low-temperature environments. The Raman spectroscopy and scanning electron microscopy (SEM) results show that the CNTs grown on the surface of 304 SS have different morphologies. The stainless steel samples with different CNT morphologies are tested by hydrophobicity and in situ icing experiments to prove that vertical CNTs can achieve a superhydrophobic state and have good anti-icing properties. The interfacial contact resistance (ICR) of the bare 304 SS and the 304 SS with vertical CNTs is compared by voltammetry, and then the corrosion resistances of both types is compared in a simulated PEMFC environment via a three-electrode system. Consequently, the ICR of the 304 SS with vertical CNTs was lower than the bare 304 SS. The corrosion potential was positive, and the corrosion current density was greatly reduced for the stainless steel with vertical CNTs grown directly on its surface when compared with the bare 304 SS. The experimental results show that vertical CNTs have good application prospects as bipolar plates for PEMFCs in low-temperature environments.

    Abstract A novel processing technology based on the functionally graded and composite structured lapping and polishing plate (FG/CS-LPP) is proposed for effectively improving the material removal uniformity. The FG/CS-LPP has the characteristics of required quasi-continuous distribution of Young's modulus in the radial direction and composite structure in the longitudinal direction. Moreover, the certain variation of Young's modulus does not tend to influence the material removal uniformity and two-step processing technique makes the shrinkage deformation of the composites reduce to 0.03 mm. Based on the Preston equation, the FG/CS-LPP can realize smooth inverse proportional stress distribution and make processing parameters decoupling of K (Preston coefficient) and P (contact stress). Through numerical simulation analysis and experimental verification, the designed FG/CS-LPP successfully achieves material removal uniformity on ZrO₂ ceramic.
