To improve the corrosion resistance of 316L substrate and lengthen its useful life in marine environments, Ni-based/WC/Y2O3 cladding layers with different Y2O3 contents were fabricated on stainless steel using laser technology. The influence additives microstructure properties coatings was investigated by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, a microhardness tester, an electrochemical workstation tribometer. Results show that metallurgical bonding...
A Ni60+30%WC composite coating was prepared on the surface of Q235 steel by utilizing a high cooling rate, small thermal deformation substrate material, and good metallurgical bonding characteristics laser cladding technology. This paper focuses study coatings under different process parameters in order to select optimal provide theoretical guidance for future practical applications. The macroscopic morphology microstructure t he were investigated with help an optical microscope (OM)...
Liquid metal infiltration techniques for producing metal-matrix composites offer economic advantages. To date produced by casting have been limited to low-temperature metals such as Al, Mg and Pb because of the serious problems inherent in high-temperature casting. A technique apparatus is described which has permitted production fibre-reinforced NiAl/Al2O3 Ni3Al/Al2O3 composites. The involves liquid Al2O3 fibres under gas pressure.
ABSTRACT A gas pressure liquid metal infiltration technique for producing fiber reinforced Ni3Al/Al2O3 and composites has been described. Composite bars of 9.5 mm diameter, 150 long were produced. It was found necessary to add 0.5 at.%Ti both Ni3Al NiAl alloys obtain adequate wetting. There a strong tendency along one side the fibers causing shift opposite side. No interface reaction zone observed at optical magnifications up 1000X. composite containing 33 volume percent FP fractured 890 MPa...
