What Does Crazing Mean?
Crazing refers to a network of visual cracks on a coated metallic surface. It occurs due to tension stresses in some glassy thermoplastic polymers.
Crazing is propagated in metallic surface regions that experience high tension and leads to the formation of microvoids and small cracks. If an applied tensile stress is sufficient then these cracks elongate and break, causing the microvoids to grow and expand. Crazing has no influence on corrosion resistance.
Crazing may also be known as shallow map cracking and pattern cracking.
