High Iron Cobalt Alloy of Tungsten And Molybdenum

The present invention describes a high iron-cobalt alloy of tungsten and molybdenum. Characterized in that:

Tungsten, molybdenum, cobalt source, the source component is cobalt (37-45%), tungsten (28-35%), molybdenum (25-35%), the use of double glow plasma surface alloying technology or other surface metallurgy technology low carbon steel, pure iron, high carbon steel or low alloy steel substrate surface to form an alloy of iron, tungsten, cobalt, iron, molybdenum, cobalt or iron, tungsten, molybdenum, cobalt alloy layer is high.

The surface of the alloy composition range of the surface layer is cobalt (18 to 30%), tungsten (9 to 20%), molybdenum (5-15%) remainder Fe;

Iron, then tungsten, molybdenum, cobalt-based alloy surface hardening alloying, solution, aging skin and tissue were distributed among the base metal alloy ferritic compounds, carbon alloy martensite and a small amount of residual austenite between the body portion and the undissolved metal compound deposited between the tempered martensite and a large original fine intermetallic compound and the metal compound, the type of tissue lining the undissolved selected by different substrates.
