Silicon wafers are hard and brittle, making cross-section preparation particularly sensitive to edge chipping, microcracks, and subsurface damage. These preparation-induced artifacts can affect subsequent optical microscopy and SEM analysis.

Laser welding provides low heat input, minimal distortion, and precise weld geometry for stainless steel components. However, weld appearance alone cannot reveal the complete condition beneath the surface.

Purpose：Sample preparation method of zirconium alloy. Zirconium Zr705, compared to traditional metals like iron, copper, and nickel, exhibits lower density, reduced thermal expansion coefficient, smaller thermal neutron absorption cross-section, and excellent corrosion resistance. These properties make zirconium and its alloys highly promising for specialized applications in nuclear, aerospace, and other industries. Samples undergo mounting (TJ-2568 epoxy resin), grinding, and polishing (Alpha-610).

Purpose：Observe the microstructure of titanium alloys. Titanium alloy blades are increasingly replacing aluminum alloys and precipitation-hardened stainless steels as the preferred material for compressor blades in aerospace engines due to their exceptional specific strength. These blades must withstand operational loads at temperatures below 500°C while maintaining high room-temperature strength and creep resistance. Samples undergo cutting (Beta-400MA), mounting (FLEXPRESS fully automatic modular hot mounting machine), grinding/polishing (Alpha610), and etching with Keller’s reagent for microscopic examination (MN80 metallographic microscope).

Purpose：Observe the microstructure of thermal spray coatings. Thermal spraying is a technique that uses high-energy heat sources (e.g., flame, plasma, or electric arc) to heat spray materials (ultrafine powders, wires, or rods of metals, non-metals, or ceramics) to a molten state. The atomized particles are accelerated to high velocities and sprayed onto a substrate to form functional surface coatings. Metallographic testing evaluates the coating-substrate interface, coating microstructure, porosity, cracks, and particle melting. Samples undergo cutting (TableCut200), mounting (TJ2568 cold-curing resin), grinding/polishing (Alpha610), and microscopic examination (MN80 metallographic microscope).

Purpose：Observe the cross-sectional microstructure of silicon carbide (SiC) wafers. Compared to first-generation silicon-based semiconductors, SiC exhibits superior electrical properties such as high voltage resistance, high temperature resistance, wide bandgap, and high thermal conductivity, making it a core material for third-generation semiconductors. It is widely used in new energy vehicle power devices, photovoltaics, and rail transportation. However, the high hardness and brittleness of SiC pose challenges in metallographic sample preparation. Samples undergo cold mounting (TJ2226 cold-curing resin), grinding/polishing (Alpha610), and a 5-step grinding/polishing process.
