deposition (PCVD) and the properties of Ti(CN) films were studied. Under the appropriate temperature and pressure, Ti(CN) films on H13 mould steel surfaces had the highest micro-hardness of HV1760 at 500......
spectrometry (EDS) and optical microscopy (OM). The Vickers hardness was measured with a micro-hardness tester. The TiC/Ti5Si3 composites were obtained in a double-layer track, and the Vickers...In situ synthesis and hardness of TiC/Ti5Si3 composites on Ti-5Al-2.5Sn substrates by gas tungsten arc weldingWen-qing Yan1,2,Le Dai3,Chi-bin Gui41.

in electrolyte and rotational speed of the stirrer on the deposition rate of coatings,the nanodiamond content in coatings,the microstructure and the micro-hardness of coatings were studied.A self-made pin-on-disk tribo-meter was employed to evaluate the wear resistance of prepared coatings.Results show that the thickness of composite coating decreases with the rotational speed,while the micro hardness......
. The micro-hardness and microstructures(i.e., grain size,carbide morphology and dislocation distribution) before and after the magnetic treatment were experimentally investigated,and the mechanism......
). The relative density, micro-hardness and tensile strength of Mo products were investigated. Microstructures of surface, cross section and fracture of these products before and after HIP were observed by scanning electron microscope (SEM). The results show that the relative density, tensile strength and micro-hardness of PSF products increase from 89.7%, 44 MPa and 152 to 97.3%, 110 MPa and 321......
particles on the surface smoothness, micro-hardness and plastic deformation at room temperature and high temperature were compared. Scanning electron microscopy was employed to examine the microstructures of the as-deposited and deformed samples. The hardness, fracture strength at room temperature and elongation at superplastic temperature of the material reach HV469, 1 150 MPa and 632%, respectively......
; accepted 3 December 2012 Abstract: TiN-matrix composite coating was prepared on 45# steel by reactive high-velocity oxy-fuel (HVOF) spraying. Its microstructure, phase composition, micro-hardness, corrosion resistance in 3.5% NaCl solution and wear resistance were analyzed. The results suggest that the TiN-matrix composite coating is well bonded with the substrate. The micro-hardness measured decreases......
of dimention 4.5 mm has been grown,which is thelargest one as we know so far.The micro-hardness of Na5Eu(WO4)4 single crystal is 3.46×103 MPa.Itsrefractive index is 1.81 in white light wavelength region......
and hardness of coatings were measured by pin-on disk test and Vickers hardness test. The coatings formed in Na2SiF6 and NaF electrolytes were mainly composed of MgO and Mg2SiO4. The measured micro-hardness of coating formed in Na2SiF6 electrolyte was found to be over HV 1100, while, coating formed in NaF electrolyte possessed micro-hardness of HV ~900. These results show that the mechanical......
by tensile test, micro-hardness measurements, transmission electron microscopy and scanning electron microscopy. The micro-hardness measurements indicate that compared with un-deformed samples..., with 5% for each rolling pass. All the specimens were then artificially aged at 453 K for various time. Subsequently, Vickers micro-hardness and tensile tests were carried out to evaluate the strength......
