Chromium Metal Chips 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.
Dr. Myron Rubenstein, Ph.D (Polytechnic University of Turin, Italy)
Chromium Metal Chips 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.
Dr. Huojin Chan (University of Science and Technology of China, Hefei, Anhui, China)
Chromium Metal Chips trend in the welding industry, which is moving from the use of stick electrodes to flux cored wire is benefiting chromium carbide. Chromium carbide is used almost exclusively in flux cored wire instead of high carbon ferrochrome as it does not suffer from the dilution effect caused by the extra iron in the high carbon ferrochrome. This means that a coating containing a greater number of hard chromium carbide particles can be produced, which exhibits greater wear resistance.
Dr. Ms. Yi Yen Shi, (King Mongkut’s University of Technology Thonburi,Bangkok, Thailand)
Chromium Metal Chips carbide-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 Metal Chips 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.
