High-temperature erosion is a detrimental phenomenon in industries where particle flow exists, which the search for new materials and mixes to increase lifespan of mechanical components exposed crucial. The present work studied resistance two coatings at 25 °C (RT) 900 sandblast-type rig. were fabricated with cermet-type powders: (C1) commercial Cr3C2-NiCr (C2) mixed laboratory-conditioned powd...

Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...

As a main part of hydraulic cylinder, the piston rod is used in tough surrounding and corrosive condition; consequently a high quality protecting layer is essential. Currently EHC, electroplating hard chromium (hard chrome) is a widespread method for piston rod due to powerful performance and low cost. Unfortunately the plating process contains hexavalent chromium (Cr) which is toxic and carcin...

A Cr13Ni5Si2-based composite coating was successfully deposited on copper by pulse laser induction hybrid cladding (PLIC), and its high-temperature wear behavior was investigated. Temperature evolutions associated with crack behaviors in PLIC were analyzed and compared with pulse laser cladding (PLC) using the finite element method. The microstructure and present phases were analyzed using scan...

A Cr3C2-Al2O3-NiCr composite coating was prepared on an INCONEL600 alloy surface through high-velocity oxygen-fuel spraying followed by further processing high-energy shot peening to create the coating. The microhardness and friction properties of are analyzed a tester reciprocating tester. microscopic structure wear trace were scanning electron microscope (SEM). element distribution energy-dis...

Abstract Cermet coatings such as WC-Co and Cr3C2-NiCr are frequently applied by means of thermal spray processes to protect highly stressed surfaces against wear. The investigation the respective materials their coating properties in-flight particle often carried out in separate experiments. In this study, characteristics (hardness, deposition rate, porosity, thickness) (particle velocity tempe...
