When it comes to gypsum rock, don’t just think of construction gypsum boards! This sedimentary rock formed from calcium sulfate minerals has plenty of hidden talents. Its formation dates back to ancient oceans or lakes. As water evaporated, calcium sulfate crystals gradually precipitated and compacted, eventually forming the gypsum rock we see today. It is […]

Thermal spray coating is known as the “protective armor” for industrial components, widely used in machinery, aerospace, energy and other fields. It not only provides wear-resistant protection for easily worn shafts and blades, but also builds a corrosion-resistant barrier for pipelines and containers in corrosive environments. Additionally, it can realize functions such as heat insulation […]

New energy power battery modules impose extremely high requirements on the reliability of electrical connections. Aluminum busbars, thanks to their excellent electrical conductivity and lightweight characteristics, have become key connecting components inside the modules. Laser welding technology, with its advantages of high energy density and precise heat input, effectively resolves process challenges such as oxidation […]

Aluminum, a lightweight metal with balanced properties, is limited in high-end applications by its inherent insufficient strength and heat resistance. Aluminum matrix composites achieve performance breakthroughs by incorporating nano-scale or micro-scale reinforcement particles, while retaining aluminum’s excellent characteristics. Through interactions with dislocations (such as hindrance and surrounding) and load transfer effects, reinforcement particles effectively impede […]

Objective: Grind and polish the chip end face to a mirror finish, ensuring end face perpendicularity and no edge chipping. Key Challenges: Silicon-based chips are brittle, small in size, and difficult to fix during sample preparation. Material: Silicon-based chip Equipment & Accessories Equipment: Semipol high-precision grinding and polishing machine Accessories: Thin-sheet sample mounting fixture Consumables […]

Preparing high-temperature oxidation-resistant ceramic coatings on niobium and niobium alloy substrates is a key surface technology to extend their excellent high-temperature strength for applications in oxygen-containing environments. The core challenges in this field lie in resolving the enormous thermal stress caused by the mismatch in thermal expansion coefficients between metals and ceramics, as well as […]
