What is Electroplating?

Electroplating is a process in which electric current causes metals to deposit uniformly on the surface of workpieces. The metallic layer primarily serves to protect against corrosion, resist mechanical wear, or improve electrical conductivity. Additionally, electroplating may aim to achieve …

What Are Chromates and Where Are They Used?

Airplane propeller - What Are Chromates

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 …

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 …

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 …

Phosphating with Iron, Zinc, and Manganese

« Overview of Phosphating Processes » Phosphating refers to surface treatment processes that create specific protective layers on metal surfaces made of iron, zinc, or manganese. These layers are electrically insulating and contribute to corrosion protection, improved paint adhesion, or …
