High-pressure laminates (HPLs) are widely utilized in interior applications but may have potential as exterior building facade coatings if suitably enhanced for weatherability. Nanoparticle additives are a promising approach to improving the durability and functionality of HPLs. This study aims to evaluate titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ) nanoparticles incorporated into HPLs to determine if they impart properties for durable, functional exterior facades. Methods: HPLs were fabricated with 3.75 wt % TiO 2 and SiO 2 nanoparticles in the surface overlay. Industry-standard EN 438 tests characterized the quality, optical properties, and accelerated aging, including UV radiation, weathering, and thermal shocks. Properties were measured before and after aging to compare versus a standard HPL without nanoparticles. Nanoparticles not only increased initial solar reflectance but also caused color changes. After aging tests, nanoparticles did not sufficiently enhance durability compared to the standard HPL. While initial reflectance improved with nanoparticles, overall weatherability did not, indicating a need to optimize fabrication and nanoparticle selection. Although TiO 2 and SiO 2 nanoparticles increased initial HPL reflectance, the feasibility of durable facade coatings was not conclusively demonstrated. Further research should focus on ideal fabrication methods, nanoparticle types and concentrations, and performance in real-world conditions to facilitate adoption in building facade applications.

“…Aligning with actual working conditions, boundary conditions for the work rolls were defined, encompassing convective heat transfer between the roll and the cooling water injection area, as well as heat conduction between the roll and the rolled piece. Subsequently, the simulation captures the temperature field distribution of the work rolls throughout the rolling process, establishing a transient finite element model for the roll [21].…”

Addressing the challenge of roll loss and strip deformation arising from the lack of precise prediction of the roll temperature field in hot tandem rolling mills, this study employs numerical analysis via the finite difference method. Based on the roll temperature field and hot roll crown model, an intelligent support cooling control system for the roll cooling water of hot rolls is established. This system comprehensively considers the direct impact of specific parameters on the roll temperature field in the intricate context of cooling water dynamics. The study focuses on the cyclic superposition effect of rolling coil quantities on the roll temperature field and the resulting hot roll shape, and theoretical calculations along with simulation analyses were conducted using finite element software. Through the integration of field-measured values, the study achieves accurate predictions of the temperature field and hot roll profile for both work rolls and backup rolls.

There is a huge demand for high-performance materials in extreme environments involving wear and corrosion. High chromium white cast irons (HCWCIs) display better performance than many materials since they are of sufficient hardness for wear protection and can be tailored in chemical compositions to improve corrosion resistance; however, their performance is often still inadequate. This article reviews the chemical composition and microstructure design aspects employed to tailor and develop HCWCIs with combined corrosion and wear resistance. The performance of these alloys under wear and corrosion is reviewed to highlight the influence of these parameters in the industry. Existing challenges and future opportunities, mainly focusing on metallurgical alloy development aspects like chemical composition, casting, and heat treatment design, are highlighted. This is followed by suggestions for potential developments in HCWCIs to improve the performance of materials in these aggressive environments. Many variables are involved in the design to obtain suitable microstructures and matrix composition for wear–corrosion resistance. Computational modeling is a promising approach for optimizing multi-design variables; however, reliable field performance data of HCWCIs in wear–corrosion environments are still inadequate. Quantitative evaluation of the wear–corrosion performance of HCWCIs requires the development of laboratory and field tests using standard conditions like abrasive type and sizes, severity of loading, slurry velocity, pH, and temperature to develop wear–corrosion maps to guide alloy development.
