Plasma Coating of Molybdenum High-Speed Steel: Structural Phase States and Properties
УДК 669.14.018.252
Abstract
The paper studies the structure and mechanical and tribological properties of the plasma coated layer surface of molybdenum high-speed steel on a substrate of medium-carbon steel 30KhGSA in a nitrogen environment. It is found that the coated layer has a polycrystalline structure and contains eutectic interlayers. The eutectic grains are formed by alternating layers of Me23c6 or Me6c carbide and layers of the a-phase. There are monolithic inclusions of Me c or Me c carbides along the grain boundaries of the a-phase. The multiphase structure of the coated layer is represented by the a-phase (solid solution based on the bcc crystal lattice of Fe), у-phase (solid solution based on the fcc crystal lattice of Fe), carbides of complex composition Me23C6 and Me6C, and Fe2C iron carbide. The formation of the coated layer is accompanied by a martensitic у -> a transformation with the formation of a lamellar martensite structure. The nanohardness of the coated layer reaches 14 GPa, the Young's modulus is 257.9 GPa, the wear parameter is 2.04 10-6 mm3/N m, and the friction coefficient is 0.75.
