“…Microstructure of the Zr-2.5Nb alloy observed by the SEM-EDX test was shown in Figure 2. Based on micro structure observation the grain of Zr-2.5Nb showed mainly equiaxed structure with relatively fine grain confirmed with the results of microstructure of the Zr-Nb alloys that revealed the increase of mechanical properties [13,14]. The main structure was relatively fine grain equiaxed structure that dispersed uniformly.…”

Synthesis and sputtering of the Zr-2.5Nb alloys were performed for the dental implant material candidate. The alloy was synthesized by casting process in an arc melting furnace with an argon atmosphere in the composition of Zr-2.5 Nb (wt %). Surface treatment was carried out by Ti-N sputtering process with the current of 20 Ampere for 45 minutes. Characterization of the microstructure was performed by the SEM-EDX test followed by the phase identification using the XRD analysis. The hardness was measured in the Vickers Hardness Number method to evaluate the relation of the microstructure to the mechanical property before and after the sputtering process. A homogeneous structure with relatively fine grain was found in the synthesis of Zr-2.5Nb alloy. The layer thickness of Ti-N was formed with the mean thickness of 0.5 micrometers. Increasing of hardness was observed in the surface of the alloy that predicted improving the compatibility for dental implant material.

“…High-current pulsed electron beam technology can solve the above problems. As a high-density energy source, HCPBE can achieve energy deposition on the material surface in a short time, irradiating the metal surface for rapid heating and cooling [11][12][13][14][15]. According to the literature, HCPEB treatment can refine the surface microstructure of metal, induce the melting of the aluminum matrix on the surface, fill the pores of the material and greatly improve the wear resistance, hardness and other properties [16][17][18][19][20][21].…”

High-current pulse electron beam (HCPEB) is an advanced surface modification technology developed in recent decades. This paper focuses on the effect of 0.3 wt.% graphene on the electrical conductivity and microhardness of HCPEB-treated Al-20TiC composites. The SEM results show that the titanium carbide was uniformly distributed in the aluminum matrix of the initial sample. Conversely, the graphene showed a small aggregation, and there were holes and cracks on the top surface of the sample. After HCPEB modification, the agglomeration of graphene gradually improved, and the number of surface pores reduced. The X-ray diffraction results show that after HCPEB treatment, the aluminum diffraction peak widened and shifted to a higher angle and the grain was significantly refined. Compared with the initial Al-20TiC composite samples, the conductivity of graphene-modified HCPEB-treated sample increased by 94.3%. The microhardness test results show that the microhardness of the graphene-modified HCPEB-treated sample increased by 18.4%, compared with the initial Al-20TiC composite samples. This enhancement of microhardness is attributed to the joint effects of fine grain strengthening, dispersion strengthening of the second phase, solution strengthening and dislocation strengthening. In brief, HCPEB has good application prospects for powder metallurgy in future.

“…However, surface modification can achieve better surface quality, thereby increasing the service life of the material [13]. Recently, high-current pulsed electron beam technology (HCPEB), a surface modification micro-structure optimization technology, has attracted considerable attention because it is not affected by ion impurities, as ion beam technology is, and it has a much higher energy efficiency than the laser beam [14][15][16]. Ivanov et al used a highcurrent pulsed electron beam to process hypoeutectic Al-Si alloy and found that because of the presence of the submicron Al-based solid solution formed by HCPEB irradiation and nano-scale structure at the grain boundary, the hardness of the surface layer increased by 3.8-4.2 times [17].…”

In this paper, the effect of rare earth Ce on the corrosion resistance of Al-20SiC composites treated with high-current pulsed electron beams is investigated, and the corresponding corrosion mechanism is proposed. The scanning electron microscope (SEM) results show that cracks arise on the surface of Al-20SiC composites prepared by pressureless sintering. After electron beam treatment, the pores on the surface are reduced because of the filling of Al liquid. After adding CeO2 to Al-20SiC composites, the wettability between Al and SiC phases is improved, thus realizing metallurgical bonding of the two phases, and microcracks generated after HCPEB treatment are significantly eliminated. Glancing X-ray diffraction (GIXRD) results show that after electron beam treatment, aluminum grains tend to grow more favorably with the stable and dense crystal plane of Al(111), thus improving corrosion resistance. The electrochemical test results show that the corrosion current density decreases by one order of magnitude with increase in the number of pulses because of rare earth Ce compared to the initial Al-20SiC composite specimens, indicating that the corrosion resistance of the Al-20SiC-0.3CeO2 composite is improved. This is because rare earth not only eliminates microcracks, but also changes the type of corrosion from localized to uniform, thus improving corrosion resistance. The Al-based composite material modified by electron beam and rare earth has many potential applications and development prospects.
