Title: Hydrothermal corrosion of silicon carbide joints without radiation

Abstract

In this paper, hydrothermal corrosion of four types of the silicon carbide (SiC) to SiC plate joints were investigated under pressurized water reactor and boiling water reactor relevant chemical conditions without irradiation. The joints were formed by metal diffusion bonding using molybdenum or titanium interlayer, reaction sintering using Ti—Si—C system, and SiC nanopowder sintering. Most of the joints withstood the corrosion tests for five weeks. The recession of the SiC substrates was limited. Based on the recession of the bonding layers, it was concluded that all the joints except for the molybdenum diffusion bond are promising under the reducing environments without radiation. Finally, the SiC nanopowder sintered joint was the most corrosion tolerant under the oxidizing environment among the four joints.

  • Ceramic matrix composites are being developed to operate at elevated temperatures and in oxidizing environments. Considerable improvements are being made in the creep resistance of SiC fibers and hence in the high-temperature properties of SiCf/SiC composites; however, more needs to be known about the stability of these materials in oxidizing environments before they will be widely accepted. Experimental weight change (1,2) and crack growth data (3,4) supports the conclusion that O2 enhanced crack growth of SiCf/SiC occurs by more than one mechanism depending on the experimental conditions. This data suggests an oxidation embrittlement mechanism (OEM) at temperatures below 1373?K andmore » high O2 pressures and an interphase removal mechanism (IRM) at temperatures of about 700?K and above and low O2 pressures. The OEM, as proposed by Evans et al. (3), results from the reaction of O2 with SiC to form a glass layer on the fiber or within the fiber-matrix interphase region. The fracture stress of the fiber is reduced if this layer is thicker than a critical value (d>dc) and the temperature is below a critical value (TTg for d>dc. This paper summarizes the evidence for the existence of these two mechanisms and attempts to define the conditions for their operation.« less
  • The purpose of this work was determination of the influence of phase composition on the corrosion resistance of high-silicon steels and their weld joints. The investigations were made on steels with an austenitic structure, including niobium-stabilized (type O2Kh8N22S6) and a ferritic-austenitic (type 10Kh12N10S6). The experimental steels were produced by melting in the 7-kg crucible of an open induction furnace with subsequent forging and rolling into 12-mm-thick plates at 1100/sup 0/C. The weld joints were produced with the use of manual and automatic argon-arc welding with the use of fillers with the same composition as the base metal. The metallographic investigationsmore » of the steels were made on a microscope and the microhardness of the structural constituents was determined. The chemical composition of the phases was determined on a microanalyzer. The tendency of the steels toward intergranular corrosion was investigated.« less
  • Seven tabular fragments of hexagonal (presumably alpha -) silion carbide were ground into a shape suitable for Fizeau interferometer measurements, in which their lengths were compared with similar vitreous silica posts. Three of these were irradiated in a nuclear reactor for about 1.08 x 10/sup 20/damaging neutrons/cm/sup 2/, three for about 1.80 x 10/sup 20/ and one was retained as a standard. They were measured again after the irradiations, and their densities were also determined. From these data the fractional expansions along the optic axis and perpendicular to it were calculated and were found to be in the ratio 0.97more » for both irradiations. (auth)« less
  • The present work is a review of the substantial effort that has been made to measure and understand the effects of corrosion with respect to the properties, performance, and durability of various forms of silicon carbide and silicon nitride. The review encompasses corrosion in diverse environments, usually at temperatures of 1,000 C or higher. The environments include dry and moist oxygen, mixtures of hot gaseous vapors, molten salts, molten metals, and complex environments pertaining to coal ashes and slags.
