Ceramic Shot Z210, Z425 Application for Aircraft Impeller Shot Peening
| Aircraft engine impellers and turbine blades are core aerospace precision components, usually manufactured from titanium alloy, high-temperature alloy and special stainless steel. After precision machining, casting and heat treatment, the workpiece surface inevitably generates micro tool marks, residual stress, tiny microcracks and oxide layers. These defects can easily cause fatigue failure under high-speed rotation, high temperature and alternating load operation. Shot peening strengthening is an indispensable core process to eliminate residual stress, improve surface fatigue resistance and extend component service life. Ceramic shot Z100 to Z850 series are professional aerospace-grade peening media that fully comply with SAE AMS2431/7 aerospace ceramic shot specifications, featuring high hardness, ultra-toughness, uniform spherical shape and zero iron contamination. Widely used for precision cleaning and strengthening of aircraft impellers. Z210 & Z425 are the most versatile mainstream grades for aircraft impeller peening. They achieve an optimal balance of stress relief and surface finishing, suitable for conventional shot peening strengthening of turbine impellers and compressor wheels. These grades thoroughly eliminate machining residual stress, form stable residual compressive stress on the metal surface, and significantly enhance fatigue resistance and high-temperature corrosion resistance. They deliver consistent surface roughness, ensuring stable aerodynamic performance of the impeller during long-term high-speed operation. Compared with traditional steel shot and glass beads, Z-series ceramic shots have low breakage rate, high recyclability and stable particle size consistency. They produce no metal contamination, no embedded particles and minimal dust, perfectly meeting the strict cleanliness and precision requirements of aerospace parts. The full-size coverage of Z100 to Z850 enables customized graded peening solutions for different impeller structures, precision requirements and strengthening standards, making them the preferred professional media for aircraft engine impeller shot peening treatment. |
