What Is a Carbide and How Does It Work?
What Is a Carbide. A carbide is a compound that consists of carbon and a metal. It can be formed by various methods such as direct combination of the elements at high temperatures or the reaction of a metal compound with carbon. Carbiding or carburizing is a process that produces carbide coatings on metal pieces.
