Abstract:

A magnetorheological material containing iron alloy particles demonstrates magnetorheological strength dependent upon the elements of the alloy and relative concentration of the alloy elements. Selected iron/cobalt alloys demonstrate improved yield strength over traditional carbonyl iron based MR materials when the iron-cobalt alloy has an iron-cobalt ratio ranging from about 30:70 to 95:5. The iron-nickel alloys which have an iron-nickel ratio ranging from about 90:10 to 99:1 maintains superior strength over iron-nickel alloys outside that range.

This article presents the results of an X-ray spectral microanalysis of cobalt-chromium alloys based on particles of the of the tungsten nickel iron alloy dispersed by electric erosion, obtained in alcohol. It has been experimentally proved that a part of oxygen is present in the cobalt-chromium alloy of particles of the cobalt-chromium-molybdenum alloy dispersed by electric erosion. All other elements are distributed relatively evenly over the volume of particles. It is shown that Co, Cr and Mo are the main elements of the (CoCrMo) alloy dispersed by electric erosion.

An industrial converter slag was treated by a selective reduction-roasting process to recovery cobalt and copper in this study. To maximizing the recovery of cobalt and copper, the major process parameters such as reducing agent, curing agent and roasting temperature were investigated.

According to the mineralogical analysis, it is found that cobalt in the converter slag mainly distributes in the iron-bearing minerals, which migrates with iron during the reduction-roasting process.

A special place among high-entropy alloys is occupied by compositions based on aluminum and transition metals (nickel, iron, cobalt) due to their service characteristics comparable with some bulk-amorphous compositions.

Ammonium tartrate and ammonia solution were used as complex forming additives to stabilize the Fe2+ and Co2+ ions and to enhance co-deposition with platinum complexes. The as-synthesized thin films were characterized by energy dispersive

Abstract:

Background and Introduction: Metal oxides (MOs) have been extensively used in a large range of engineering and medical applications. Methods: FeCo nanoparticles (NPs) were successfully synthesized by the solgel method in the presence of a powerful reducing agent-sodium borohydride (NaBH4). The structure, morphology, and optical properties of NPs were analyzed by X-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR) at room temperature. Results: The XRD spectrum showed the body cente

Abstract:

Magnetoelectric barium titanate ceramics with embedded cobalt iron alloy particles (Co1/3Fe2/3)x–(BaTiO3)(1−x), with x=0.2, 0.4, and 0.6, were prepared by a polyol-mediated synthesis with subsequent sintering in a reducing forming gas atmosphere. The samples were characterized by XRD and SEM/EDX measurements. The sizes of the Co1/3Fe2/3 grains increase with x. Impedance spectroscopy showed a behavior similar to pure BaTiO3, in particular the occurrence of the ferroelectric-paraelectric phase transition, and high permittivities for the sample with x=0.6, that is, near the percolatio

Abstract:

High entropy alloys (HEAs) are a newly developed family of multi-component alloys composed of several major alloying elements, such as copper, nickel, aluminum, cobalt, chromium, iron, silicon, titanium, etc. The fact that HEA alloys is formed participation molar is approximately equal with at least five elements, entropy configuration is double that of binary systems, entitles us to call them "high entropy alloys'. Recent studies suggested that the refractory HEAs exhibited great promise for high temperature structural materials. This alloy can be processed and analyzed as an ordinary materia

Abstract:

Considering the issues of significant ammonia volatilization loss and toxic gas emission associated with the conventional ammonia leaching method used in the resource utilization of cobalt-rich alloy slag, a novel approach involving selective complexation leaching of cobalt in an alkaline histidine solution has been proposed. Under conditions of 35 °C temperature, a molar ratio of histidine to cobalt of 1.5, pH of 8, a leaching period of 12 h, and a stirring speed of 300 rpm, the cobalt leaching rate from cobalt-rich alloy slag exceeds 95%. In contrast, the leaching rates for impurity metals s

Abstract:

Abstract As a key component in the hot-dip galvanizing production line, the sink roller ends of the sliding bearing is affected by the high-temperature zinc liquid corrosion wear, which leads to frequent stop for maintenance. The galvanizing industry is looking for more suitable material for bearing to prolong the service life. To improve the corrosion and wear resistance of the sliding bearing, the laser cladding method was used to prepare the cobalt-based and iron-based coatings on the surface of the superalloy. In this paper, the high-temperature zinc liquid corrosion wear test was carried

Abstract:

The dry sliding wear behaviors of iron and cobalt-based high-temperature alloys against Al2O3 with different sliding speed under various loads were investigated using a ball-on-disc tribo-tester. The friction coefficient of both high-temperature alloys decreased with the increasing speed and load. The GH605 exhibited the stronger wear resistance than GH2132 under all test conditions. The adhesion layer and oxides were found on the worn surface of Al2O3, and the high-temperature alloy would react with air and the wear mechanisms might be adhesive wear and oxidative wear.
