Knurling adds textured patterns to surfaces, enhancing grip and bonding. Applied by machine or hand-applied, it’s used in tools, connections, and over-molding.
-
Shot peening is a crucial metal treatment process that enhances the fatigue resistance, durability, and surface hardness of components. This technique involves firing small beads at high velocity onto a material’s surface, inducing compressive stress and improving mechanical properties.
-
Galvanisation coats iron/steel with zinc to prevent corrosion. The process helps to improve durability and lifespan.
-
Black oxide coating is a chemical surface treatment for ferrous materials which enhances corrosion and wear resistance.
-
Passivation builds a protective layer on metal surfaces, enhancing corrosion resistance. It’s vital for stainless steel, restoring protection after fabrication.
