Thermal spraying is an advanced surface engineering technology that heats materials to a molten or semi-molten state, then sprays them onto a substrate surface at high velocity to form a functional protective coating. Like applying custom-made armor to workpieces, it significantly improves key properties including wear resistance, corrosion resistance, high-temperature resistance, thermal insulation, electrical insulation or conductivity. From flame spraying,

Titanium alloys are strategic materials for aerospace, medical & high-end industries. However, they are difficult to prepare due to heat sensitivity, edge rounding, and deformation layers. Here is the optimized metallographic preparation workflow fully compatible with Trojan equipment: ✅ Cutting:Use Trojan Tablecut 200 precision cutter with dedicated blades to avoid overheating, burning, sticking, and work hardening. ✅ Mounting:Use low-shrinkage edge-preserving

EBSD (Electron Backscatter Diffraction) is a “microscopic perspective lens” for the R&D and quality control of alloy steel! It accurately captures core microstructural information including grain orientation, grain boundary characteristics, phase distribution and dislocation density, revealing the correlation between microstructure and mechanical properties such as strength, toughness and corrosion resistance. It provides direct evidence for optimizing rolling and heat treatment

Magnetic cores are magnetic components made of ferromagnetic materials (e.g., iron, silicon steel, ferrite), designed to concentrate and guide magnetic fields. They are indispensable core parts in numerous electronic and electrical devices. Key Functions of Magnetic Cores ✅ Magnetic field concentration: Gather the magnetic field generated by coils to boost inductance, enabling more compact and efficient components. ✅ Energy conversion:

As the core acoustic component of mobile devices, smartphone speakers rely on precision micro-welding and assembly to deliver Hi-Fi sound in ultra-slim designs.

In the industrial kingdom woven by steel and iron, welds never seek the spotlight, yet they hold the core power to prop up countless pieces of equipment and projects, truly deserving the name of invisible “life veins”. From the steel structures of bridges spanning rivers, to the aero-engines soaring through the sky; from the shells of deep-sea submersibles exploring the

As high-performance heat transfer components, finned tubes boost heat exchange area dramatically by adding fins to the base tube surface. This enables more compact, efficient heat transfer—making them indispensable across key industrial sectors. The welding quality between fins and base tube is non-negotiable for equipment safety & lifespan. Secure metallurgical bonding is a must to avoid defects like cold welding

In the manufacturing of drill bits and cutting tools, metallographic inspection of metal powders prior to sintering serves as the fundamental guarantee for quality control. By preparing and observing raw powder samples, the internal microstructure can be directly evaluated—including the degree of pre-alloying, morphology of primary carbides, and purity—thus predicting the uniformity of the sintered structure. This inspection effectively identifies

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 not only visually appealing—some varieties

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 and electrical conductivity for high-temperature

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.

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 dislocation movement, enabling the material
