In order to improve service life of hot forging die, Ni60-SiC cermet coating was prepared on the high speed steel W6Mo5Cr4V2 under different processing parameters using plasma cladding technology. The clad coating composition, microstructure and microhardness were analyzed by X-ray diffractometer (XRD), optical microscopy (OPM) and microhardness tester. The experimental results show that Ni+25 wt...
In order to satisfy performance and long life requirements for hot forging die, Ni60-SiC cermet coating was prepared on the high speed steel W6M05Cr4V2 by plasma cladding technology. Metallurgical bonding coating with enough bonding strength was obtained after optimizing the cladding parameters. The clad coating composition, microstructure, microhardness and thermal physical parameters were analyzed...
Summary form only given. Sintered Co(Cr)-MoB materials have a good combination of high modulus, high wear resistance, high corrosion resistance and adequate fracture toughness, making them suitable for many industrial applications such as metal-cutting tools and wear resistant components. In many applications, they are superior to oxide and carbide coatings. Recently, boride- based cermet surface...
