SANDBLASTING

Among the surface treatments offered by Zincoplating, we also provide steel micro-bead sandblasting, available in two types:

  • Micro-sandblasting, performed with fine steel sand particles, used to mechanically remove micro-impurities that may form on metal surfaces.
  • Angular sandblasting, used when a specific surface roughness is required on metal components.

HYDROGEN DE-EMBRITTLEMENT

Hydrogen de-embrittlement is a thermal treatment performed after the galvanic process, particularly when coatings are applied to high-strength metals. During the pickling and electroplating processes, hydrogen can become trapped within the metal structure, leading to brittleness and potential failure. To counteract this, the treated components undergo heat treatment at 180–200°C, or at other specified temperature/time settings according to industry requirements. This process releases the trapped hydrogen from the metal’s molecular structure, restoring its mechanical integrity and ensuring optimal durability.
