A Full-Process Quantitative Analysis Method of the Content of Antimony Sulfide Based on Raman Spectrum

Zhou Li Degang Xu Yaoyi Cai Lei Zhang Kun Wan

The content of antimony sulfide is an important index in the antimony flotation process, which directly determines the amount of reagent added and the parameters of control equipment in the process of antimony flotation. Chemical detection methods are mainly used for analysis at present time, and the operation is so complicated that the detection process takes a long time, which cannot meet the requirements of real-time during the flotation process. Based on the analysis technology of Raman spectroscopy, the purpose of this article is to propose a full-process quantitative analysis method of the Raman spectra of antimony contents in the raw ore samples based on Raman spectroscopy. Several strategies were proposed to establish the best model: these strategies included preprocessing methods (de-nosing, baseline correction), selecting characteristic wavelength for the quantitative analysis of antimony sulfide, and building a multivariate calibration model. According to the content of antimony sulfide in the main steps of antimony flotation, a multivariate calibration model of antimony sulfide content based on LWMKPLS for quantitative analysis is proposed. This model trains and tests the model separately by dividing the data of antimony sulfide contents in the raw ore samples into a training set and a validation set, which proves that the method can improve the accuracy of prediction of the quantitative analysis model. This method provides a new way for the quantitative analysis of the content of antimony sulfide minerals.

Coating Microstructure, Surface Roughness, and Jetting Behavior in Cold Spray: A Multi-Particle Impact Model

Che Zhang Zhou Li Jarrod Watts Peng Gao Jiaqing Li

While the single-particle impact model is widely used in studying the cold spray process, its scope is restricted to the interaction between an individual particle and the substrate, providing very limited insight into the coating's internal structure and surface roughness. In this work, a multi-particle impact model was specifically established to investigate the microstructural characteristics and surface quality of nanostructured Cu coatings. It was found that with the increase of impact velocity from 100 m/s to 1500 m/s, three distinct coating structures can be identified: adhesion between nanoparticles, co-deformation, and liquefaction. Furthermore, due to the anisotropy of plastic deformation, coatings formed by particles with the initial orientation [110] displayed the roughest surface, while those aligned with [111] and [001] exhibited smoother surfaces. Additionally, as nano-scale particles possess limited kinetic energy, it is difficult for them to induce plastic deformation on the surface and within the substrate. Therefore, it was necessary to elevate the temperature to soften the substrate, only then could jetting be induced with larger adhesion areas. A successful approach to enhance surface quality and bonding strength of coatings involves simultaneous control of impact velocity, crystallographic orientation of particles, and substrate temperature.

Improving the strength and retaining the ductility of microstructural graded coarse-grained materials with low stacking fault energy

Materials & Design (2018)

Ji Gu Lixin Zhang Yahui Tang Min Song Song Ni

Gradient structures were introduced via torsional treatment to Cu and CuAl alloys with different starting grain sizes and stacking fault energies (SFEs). Systematic investigations showed that the original grain sizes and SFEs of these materials play vital roles in affecting the formation of gradient structures and their corresponding mechanical properties. Large grain size and relatively low SFE are two critical requirements for the formation of the optimum gradient structure. A superior combination of high strength and good ductility can be achieved by torsional treatment in ultra-coarse-grained materials with low SFEs, which is attributed to the hierarchical structures that led to the simultaneous activations of different deformation mechanisms from full dislocation activities to partial dislocation slip and nano-twinning along the radial direction.

Effects of Cooling Rate on the Microstructure and Tensile Strength of A356 Alloy Wheels

Zhenbang Liu Zhou Li Guowei Li

In this work, the effects of cooling rate on the microstructure and tensile strength of A356 wheels during solidification were studied.Four cooling methods, including air cooling, wind cooling and two different water coolings, were a used to control the cooling rate of spoke.Comparing with the air cooling and wind cooling, at higher water cooling rates, the iron phase appeared from the peritectic-type reaction, which transformed from the previous β-Al 5 FeSi phase to π-Al 8 Mg 3 FeSi 6 phase.Besides, as cooling rate increased from 0.69 °C/s to 1.95 °C/s, the secondary dendritic arm spacing (SDAS) declined from 44.41 μm to 31.86 μm.The UTS and YS could reach 225.27Mpa and 143.02Mpa in the water cooling with the minimum water flow velocity (16L/h), respectively.
