Abstract
The invention discloses an oxidation and decarbonization preventing treatment process for a workpiece. A double-layer coating is adopted to carry out an oxidation and decarbonization preventing treatment process, so that oxidation and decarbonization during thermal treatment is greatly reduced; after the workpiece is heated, the coating can be automatically peeled off from the surface of a basal body; and the oxidation and decarbonization preventing treatment process is simple and convenient in operation, and has a good application prospect.
Description
Technical field
The present invention relates to metal heating processing technology field of material technology, particularly relate to a kind of workpiece anti-oxidation decarburizing treatment process.
Background technology
Under oxidizing atmosphere, steel workpiece surface and superficial oxidation decarburization can cause workpiece surface hardness to decline, workpiece generation early stage of fatigue is damaged, affect workpiece surface and total quality, the oxidation and decarbonization of workpiece surface generally cannot be avoided, and always the non-oxidation carbonization treatment how realizing workpiece in common electric furnace pursues the problem of solution in industry.
