Chromates, which are chemical salts derived from chromic acid, play a role in two distinct surface treatment processes: Chromating, where chromic acid or its salts create a chromate layer on a material’s surface. Chromium plating, where dissolved chromates (electrolytes containing …

Overview: Deburring Metal
« Effective Methods at a Glance » Have you ever accidentally snagged yourself on an overhanging piece of metal? Sharp edges, splinters, or burrs on parts made from wood, plastic, or metal not only compromise aesthetics but can also lead …

« Effectively Preventing and Removing Surface Discoloration » Colored metallic surfaces are often desirable. For instance, steel does not have to just be shiny silver; it can be colored through sophisticated processes to almost any hue, including green, blue, red, …
Read more »Pickling and Passivation
« What does it mean? » Pickling and passivation are chemical or electrochemical surface treatment processes that deliberately modify the properties of the material’s surface layers. These methods are commonly used in the pretreatment of metal workpieces to create corrosion …

« Removing Stains and Discolorations From Lightweight Metal » Aluminum is a non-precious metal, meaning it reacts readily with oxidizing agents. When exposed to air, aluminum quickly forms a dense layer of aluminum oxide on its surface. This layer prevents …
Read more »Cold Forming of Metal
Cold forming is a metalworking process where materials are shaped under significant compressive or tensile forces with or without minimal preheating. This distinguishes cold forming from hot forming, with the dividing line being the recrystallization temperature. Formation of Material Microstructure …
