Tungsten steel is formed by pressing the powder into a billet, heating it to a certain temperature (sintering temperature) in a sintering furnace, and maintaining it for a certain period of time (heating time), and then cooling it down to obtain a tungsten steel material having desired properties.
The four basic stages of the tungsten steel sintering process:
Removal of the forming agent and the pre-firing stage, in which the sintered body undergoes the following changes
The removal of the molding agent, as the temperature increases, the molding agent gradually decomposes or vaporizes at the initial stage of sintering, thereby eliminating the sintered body. At the same time, the molding agent more or less carbon is added to the sintered body, and the carbon addition amount will follow the molding agent. The type, quantity, and sintering process vary.
The surface oxide of the powder is reduced. At the sintering temperature, hydrogen can reduce the oxides of cobalt and tungsten. If the molding agent is removed by vacuum and sintered, the carbon-oxygen reaction is not strong. The contact stress between the powder particles is gradually eliminated, the bonded metal powder begins to recover and recrystallize, surface diffusion begins to occur, and the strength of the compact is improved.
