The anti-friction properties of the plasma-sprayed powder coating based on copper PG-19M-01, proposed instead of the cast bronze sleeve made of 05Ts5S5 bronze, used in the coupling of the drive shaft and gear of the T-155 transfer case pumps, were proposed and investigated in the paper. X-ray phase analysis of plasma coatings from PG-19M-01 powder showed that the main phase in the coatings is a solid solution of aluminum in copper. X-ray microspectral analysis established that the composition of the coating is heterogeneous in thickness. The results of the conducted research and field tests sh

This study was initiated to investigate the material characteristics of binder jet (BJ) manufactured austenitic stainless steel 316L, focusing specifically on the less studied bronze infiltrated version of this material. While BJ technology offers a compelling alternative to the current market leader laser powder bed fusion, all additive manufacturing methods are susceptible to porosity, which adversely affects the fatigue properties of parts, resulting in inferior fatigue life compared to traditionally manufactured counterparts. In this study, we explore the novel application of severe shot p

Temperature dependence of Ohmic resistance, and nonlinear current–voltage (I–V) characteristics at 77 K were systematically studied in pure potassium blue bronze K 0.3 MoO 3 and Na-doped alloy bronzes K 0.3-x Na x MoO 3(x = 0.02, 0.05, 0.10). No considerable influence of Na ions doping in K 0.3 MoO 3 was found on the Peierls transition temperature, while obvious enchancement on semiconductor gap and remarkable influence on the first threshold field were observed. We attribute the first phenomenon to two opposite effects of Na ions, and the depinning model is proposed to account for the latter.

Abstract The paper displays the influencing factors, as well as the possibilities and challenges that come along with the process combination of selective laser melting (SLM) and heavy wire bonding. For the investigations, test samples were created from bronze powder on a SLM-machine. Then, 300 μm aluminum and copper wires were bonded on the SLM generated structures. Wire bonding capability is analyzed on untreated as well as on post-processed surfaces. The influence and effectiveness of various steps of post-processing such as cleaning, sandblasting and grinding are analyzed. Thus, interdepen

The HPLED(2.5 W) samples were surface mounted device(SMD) package used in our experiments. The experiments were made for SWHP with diameters of 6.0 mm. The length of the SWHP is 150 mm. The working fluid in the heat pipes is pure water. The electrical-thermal transient technique was employed for the junction temperature measurement. It was found that the SWHP leads to decreased of thermal resistance by 35 % compared with a simple copper bar in oil

The wooden coffin tombs at Tap-dong are the first tombs of outstanding elites to have ever found in downtown Gyeongju, the capital of Silla. This is also where Oreung(五陵) - the tomb of Park Hyeokgeose, who is the founding monarch of Silla - is located. The Tap-dong burial sites consist of 3 wooden coffin tombs dated in different periods, numbered 1 - 3, respectively.
 There are hints from the digs at the Tap-dong site that: 1. the kind of wooden coffin tomb appeared around 57 BCE, exactly at the same time when Silla started off as a small city-state by the name of Saro-guk.

Cu–Al bronzes are interesting metallic materials, demonstrating higher hardness, higher wear resistance, higher corrosion resistance and a lower friction coefficient as compared with unalloyed copper. The powder metallurgy approach to the fabrication of these alloys presents opportunities to tailor their phase composition and grain size. In the present work, the structural characteristics, phase composition and properties of Cu-10 wt.% Al alloys obtained by spark plasma sintering (SPS) of powder blends and a powder obtained by mechanical alloying (based on Cu(Al) solid solution) are reported.

During the Bronze Age, in many Western Mediterranean areas (Spain, France, Italian peninsula, islands), we can observe the development of a series of fortified centers and structures, often on high places, aimed to the defense of strategic locations and resources. These fortifications, which began to be built from the Copper Age, are the answer to a need for possession and control of the territory linked to a greater degree of social complexity, with an ever-increasing hierarchy and the rise to power of persons or groups who very often show the possession of weapons and, consequently, can be r
