Chromium Powder is a chemical element with symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-grey, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. Chromium metal is of high value for its high corrosion resistance and hardness.
Chromium Powder are hard and their general use is to provide hard wear-resistant coatings on parts that need to be protected. When combined with a protective metal matrix, corrosion-resistant as well as wear-resistant coatings can be developed that are easy to apply and cost effective. These coatings are applied by either welding or thermal spray. When combined with other carbides, chromium carbide can be used to form cutting tools.
Chromium Powder-based coatings have a wear resistance which is between two and a half and five times better than hard chrome plating and do not suffer from effluent disposal problems. They are therefore finding increasing use at the expense of hard chrome plating, particularly if wear resistance is important or if a thick coating is required on a large part. This is an exciting and rapidly growing area which will become more important as the cost of complying with environmental legislation becomes greater.
Chromium Powder Diamalloy powders are characterized by their ability to provide wear, oxidation and hot corrosion resistance at elevated temperatures. The addition of NiCr cladding improves corrosion properties. Higher NiCr content results increased fracture toughness of the coatings.
Chromium Powder (Cr3C2) is an extremely hard refractory ceramic material. It is usually processed by sintering. It has the appearance of a gray powder with orthorhombic crystal structure. The orthorhombic Cr3C2 occurs extremely rarely as mineral tongbaite. It is highly corrosion-resistant, and does not oxidize even at high temperature (1000-1100 °C). The thermal expansion coefficient of chromium carbide is almost equal to that of steel, reducing the mechanical stress buildup at the layer boundary.
