Abstract:

This study elucidates the use of the precipitation method to enhance the uniformity of oxide additives in boron carbide ceramics. Achieving a homogeneous distribution of additives is critical, as higher additive content tends to degrade the mechanical properties of boron carbide. In this research, yttrium and aluminium hydroxide salts were dispersed and incorporated into boron carbide slurry under highly alkaline conditions. The mixture was aged and subsequently calcined to produce metal oxide layers around the boron carbide particles. The additive-to-boron carbide ratio and calcination condit

Abstract:

Boron-containing compounds are one of the lubricant additive options due to their suitable properties for additives and have been used as commercial lubricant additives. In the present study, the impact of a boron-containing lubricant oil additive, AR9100 (BR), on Pd/Rh-based three-way catalyst (TWC) performance is investigated, and the results are compared with the baseline no-additive (NA) case and the industry standard zinc dialkyl-dithiophosphate (ZDDP) results. Accelerated engine aging is performed using a genset to expose the catalysts to lubricant additives at high temperatures. All age

Abstract In view of the severe erosion and wear of gun barrels, we first briefly introduce the research status of erosion reducing additives in this article. Based on these analyses, polydimethylsiloxane (PDMS)-Na2B4O7 additive and PDMS-H3BO3 additive are designed and prepared. These two additives are very flexible and can be folded or bent in any direction. After that, the erosion reducing performance of paraffin wax (PW)-TiO2 additive, PDMS-Na2B4O7 additive and PDMS-H3BO3 additive are studied through the vented vessel test. The results show that the erosion reducing performance of PDMS-Na2B4

Pressureless sintering of hexagonal boron nitride (BN) with and without additives was performed using a powder which was previously nitrided at 900oC and then heat treated at 1400oC. Sintering additives were B2O3 (2, 4, 6 wt %) and Y2O3 (2, 4, 6 wt %) and sintering temperatures was 1900oC. Sintered samples were characterized by XRD, SEM, micro hardness, density and mercury porosimeter measurements. Maximum density values of samples were 1.56 g/cm3 without additives and 1.63 g/cm3 with additives. Hardness values of samples were found to improve with the presence of additives.

Potential replacements for ZDDP are antiwear/EP boron-based additives.

Abstract Titanium alloys containing boron additions have shown remarkable improvements in processing and mechanical behavior. Significant reductions in grain size are observed even with trace additions of boron (&lt; 0.1 wt% B) leading to benefits in processing. When the boron levels are increased to modest levels (~ 1 wt% B), the stiffness and strength of the Ti-6 Al-4 V base alloy increase by 20 – 30% with no loss in ductility. Keeping these advantages in mind, the aqueous corrosion behavior of these unique materials was investigated in this study to establish a baseline for performance

Abstract Titanium alloys with varying boron additions, in Hanks Balanced Salt Solution (HBSS), were characterized using electrochemical impedance spectroscopy (EIS) at varying exposure times. Bode and Nyquist plots were plotted for each substrate. The Bode plots point to the possible formation of a double-layered passive film on the surfaces of all the Ti-6Al-4V alloys containing boron after exposure to the solution for times of 28 to 168 h. At exposure times of 28 to 168 h, the Ti-6Al-4V-1.09B alloy did not show noticeable changes in impedance behavior with respect to increased exposure time.

Abstract:

Abstract PWSCC in Alloy 600 and Alloy 182, 132 and 82 weld metals is important because these materials are widely used in the PWR coolant system. Plant experience indicates that PWSCC will steadily increase as plants age without effective mitigation. This study is investigating the mitigation of PWSCC initiation and propagation by adjusting the current operating PWR primary water chemistry, including dissolved hydrogen, lithium and boron concentrations, the pH at temperature, and Zn additions.

Abstract:

Abstract To increase the longevity and to optimize the performance of biomedical implants, a class of β-titanium alloys, specifically Ti-Nb-Zr (TNZ) is being explored. TNZ alloys demonstrate advantageous properties including non-toxicity, biocompatibility and low elastic moduli. Moreover, previous studies have shown that the addition of trace amounts of boron (0.01- 1 wt%) in conventional titanium alloys increases the tensile strength and corrosion resistance of the alloys. The objective of this study was to investigate the corrosion behavior of UNS R58130 (Ti-13Nb-13Zr or Ti1313) as well as T

Abstract:

Abstract High gamma prime Ni-based superalloys comprising ≥3.5 % Al are difficult to weld due to high propensity of these materials to weld solidification, heat affected zone liquation, and stress-strain cracking. In this study the root cause analysis of cracking and overview on the developed weldable Ni-based superalloys for repair of turbine engine components manufactured from equiaxed (EA), directionally solidified (DS), and single crystal (SX) materials as well as for 3D AM is provided. It is shown that the problem with the solidification and HAZ liquation cracking of turbine engine compon

Abstract:

A 24-inch-diameter x 0.75-inch-wall X70 low-carbon bainitic-steel pipe was evaluated to obtain an independent measurement of pipe properties and to examine metallurgical characteristics that may affect behavior in gas-transmission service. The steel from which the pipe was produced was processed using advanced steelmaking methods to insure cleanliness but apparently was not treated for sulfide shape control since no sour gas exposure in service was anticipated. Primary microalloying additions in this high manganese steel, other than columbium, were titanium and boron. Titanium was added to for

Abstract:

Electrochemical disinfection has gained interest as an alternative to conventional wastewater treatment because of its high effectiveness and environmental compatibility. Two and a half billion people currently live without improved sanitation facilities. Our research efforts are focused on developing and implementing a freestanding, additive-free toilet system that treats and recycles blackwater on site. In this study, we sought to apply electrochemical disinfection to blackwater. We compared commercially available boron-doped diamond (BDD) and mixed metal oxide (MMO) electrodes for disinfect

Abstract:

Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level. Similarly, considerations of competition between chloride and nitrat
