“…The displacement energy and density were 25 eV and 1.8 g cm −3 , respectively. The mean ion energy of implanted Zr was set at 104 keV, which is the value of the Zr mean ion charge state multiply the ion source extraction voltage, according to the previous research [26]. The concentration of implanted Zr ions and displacement damage (dpa) as a function of depth were achieved by equations (1) and (2) [27], respectively.…”

In order to improve the surface properties and satisfy the controlled degradation of biomedical magnesium, Zr ion implantation was conducted on ZK60 magnesium with different doses in the range from 1×10 16 to 5×10 16 ions cm −2 and an accelerating voltage of 40 kV. The Zr ion concentration and displacement damage were simulated by the Stopping and Range of Ions in Matter (SRIM), the surface morphologies, structure, composition, surface mechanical properties and corrosion resistance in simulated body fluid were investigated using atomic force microscope, fieldemission scanning electron microscopy, X-ray photoelectron spectroscopy, nano-indentation, electrochemical experiments and the hydrogen evolution tests. The results indicated that the distribution of the implanted Zr concentration and displacement damage can be accurately adjusted through controlling the implanted doses, the ZK60 surface becomes smoother after Zr ion implantation along with the reduced roughness at specific doses. When the dose is 2×10 16 ions cm −2 , a gradient modified layer mainly composed of MgO, ZrO 2 and Zr, in thickness greater than 120 nm, formed on the near-surface of ZK60 after Zr ion implantation. Besides, it also possesses the largest hardness and modulus, the lowest corrosion current density and hydrogen evolution volume, indicating that the surface mechanical properties and corrosion resistance of ZK60 can be effectively improved by Zr ion implantation. Additionally, the modification mechanisms were also discussed.

Fabrication and Tribological Performance of Zr-Coated Carbide against 40Cr Hardened Steel

In order to enhance the tribological performance of YT14 carbide, pure Zr coating was deposited on the substrate surface using a multi-arc ion plating method. The surface topography, adhesion strength, thickness, and micro-hardness of the Zr coating were tested. Dry sliding friction experiments against a 40Cr hardened steel ring were conducted with Zr-coated carbides and traditional ones. The average coefficients of friction were measured and compared. The wear characteristics of the samples were examined by scanning electron microscope (SEM) and energy dispersive X-ray analysis (EDX). The test results indicated that the Zr coating deposited on the carbide surface exhibited excellent adhesive strength and lower hardness. The average friction coefficient of Zr coated carbide decreased by 20%–30% in comparison with that of the uncoated one. The Zr coated carbide could reduce the adhesive wear compared with the uncoated one, and the main tribological degradation mechanisms of the coating were abrasive wear, coating flaking and delamination.

“…The effects of nitriding, nitrocarburizing and shot peening on fatigue behavior of AISI D3 cold work tool steel are investigated by Farrahi and Ghadbeigi [1]. Sliding wear behavior of Zr-ionimplanted D3 tool steel is studied by Saklakoglu et al [2] and found that Zr implantation decreased both the wear and the coefficient of friction. The effects of the prior austenite grain size in deep cryogenic treatment on the hardness, the structural change and the wear resistance of D6 tool steel are investigated by Akhbarizadeh et al [3].…”

An experimental investigation on the strain rate sensitivity of die steel (D3) has been presented in this paper at different rates (0.001-2500s-1) of uni-axial compression. Quasi-static tests (0.001s-1) of the material are conducted on universal testing machine (UTM), whereas, the experiments at high strain rates are performed on split Hopkinson pressure bar (SHPB) apparatus. The effects of gauge length of the specimen on the material properties of the material are studied at different strain rates. The material parameters of existing Cowper-Symonds and Johnson-Cook material models are determined and the suitability of the models is examined.
