SOME EFFECTS OF VARYING SODA AND BORIC OXIDES IN GROUND COAT ENAMELS1

Variations were made from 5 to 25 % in soda oxide and boric oxide content of a given ground coat enamel, and results observed on trial pieces. It was found that an increase of soda oxide at the expense of boric oxide decreased the tendency of the enamels to blister and fishscale, and increased the tendency toward the formation of copperheads. Conversely, the increase of boric oxide at the expense of soda oxide increased the tendency of the enamels to blister and fishscale, but decreased the tendency to copperhead.     

Anodization of hafnium in phosphoric acid solutions

The kinetics of formation of anodic oxide films on hafnium electrodes either under open circuit conditions or constant current density were investigated using polarization and impedance measurements. Under open circuit conditions the oxide film was found to thicken with time following a direct logarithmic law, whereas it thickens linearly with time under galvanostatic polarization and obeys the exponential law due to Güntherschulze and Betz. An increase in phosphoric acid concentration was found to increase the rate of oxide formation and the field strength owing to incorporation of electrolyte species into the oxide during the anodization process. The break-down voltage was found to increase linearly with the logarithm of phosphoric acid resistivity and was independent of the anodizing current density. The impedance behaviour of the hafnium oxide film/solution interface was found to be purely capacitive and the impedance increases with increase in the film thickness. The film thickness was found to decrease linearly with the logarithm of time probably owing to partial dissolution of the oxide film.     

阳极电压对钛合金微弧氧化膜性能的影响

摘要：在不同阳极电压下对Ti-6Al-4V合金进行了微弧氧化处理。考察了阳极电压对氧化膜生长速率、表面形貌、相组成及硬度的影响，并对其摩擦学性能进行了表征。研究结果表明，随着阳极电压的升高，氧化膜表面微孔数量减少，表面微孔孔径、粗糙度、氧化膜生长速率均增大，表面硬度先增大后减小。微弧氧化膜主要由Al3TiO5相和金红石TiO2相组成，随着阳极电压的升高，两者相对比例逐渐增大。阳极电压对微弧氧化膜与钢球的摩擦系数影响不大，但对磨损率影响较大，磨损率随阳极电压的升高先减小后增大，氧化膜均具有较好的耐磨性。     

SOLUBILITY OF A ZIRCONIUM OXIDE OPACIFIER IN ENAMEL GLASSES*

The solubility of a zirconium oxide opacifier was determined by fusion in enamel glasses and then by heat-treating at enameling temperatures and noting the amount of crystallization. An increase in the alumina, zinc oxide, and calcium oxide content in the glasses caused a decided decrease in the solubility of the zirconium oxide opacifier. The fusion temperatures of the enamels were raised by solution of zirconium oxide.     

Numerical analysis of particle clustering effects on desulphurization and NO emission in a circulating fluidized bed combustor

Desulphurization by a calcium oxide particle cluster and an isolated calcium oxide particle in a circulating fluidized bed (CFB) combustor was numerically analyzed. The gas flow field, the sulphur retention and the nitrogen oxide emission of the cluster were predicted. Computed results showed that the SO₂ capture rate by a calcium oxide particle in the cluster is less than that of the isolated calcium oxide particle out of the cluster. The captured SO₂ and NO emissions decrease with the decrease of the cluster porosity. The maximum SO₂ capture rate by the cluster is at a temperature between 1025 and 1055 K, whereas more NO emissions were found with the increase of the gas temperature. The sulphur removal and the NO emission increase with the increase of the inlet gas velocity.

Oxide film growth on Al-In alloys in a borate buffer solution in conditions of galvanostatic anodising

Anodic oxide films have been formed galvanostatically on Al-In alloys (containing up to 0.074% In) in a borate buffer solution (pH 7.8) at different current densities (20-100 μA cm⁻²). The mechanism, kinetics of growth and properties of formed oxide films have been investigated. The study of charge curves suggests that the growth of oxide films on Al-In alloys occurs by an activation-controlled ionic conduction under the influence of the high electric field through the oxide film according to an exponential law, like on valve metals. The following parameters have been calculated: the constants of the exponential law, ionic conductivity through the film, the effective activation distance for ion movement and the corresponding field strength. The values for the field strength, of the order of magnitude of 10⁶ V cm⁻¹, justify the application of the high field migration mechanism. Properties of anodic oxide films have been determined by means of electrochemical impedance spectroscopy; the resistance and thickness of the oxide film have been found to increase with the increase in the indium content in the alloy and with increased anodic current density. It has been established that the current efficiency in oxide films formation on Al-In alloys is lower than 100%: the increase of the indium content in the alloy, as well as the increase in anodic current density, increases the value of current efficiency.     

Study of passivation of Al and Al-Sn alloys in borate buffer solutions using electrochemical impedance spectroscopy

Properties of thin oxide films on Al and Al-Sn alloys (with Sn content of 0.02, 0.09, 0.20 and 0.40 wt.%) formed either naturally or anodically in borate buffer solutions were investigated by means of electrochemical impedance spectroscopy. Equivalent circuits have been proposed that completely illustrate the Al(Al-Sn alloy)/oxide film/electrolyte systems examined, and properties of oxide films were determined. The stability (thickness and resistance) of oxide films has been found to increase with increased Sn content in the alloy, with increased passivation potential, and with longer time of anodising. The increase in temperature of anodising significantly reduces impedance in systems observed.     

Subsolidus Relations Between Mullite and Iron Oxide

The subsolidus relations between mullite and iron oxide were studied to increase the understanding of the properties of fired clay products. Solid solutions of ferric oxide and mullite were measured in the temperature range 1000° to 1300°C. The solid solutions were characterized by an increase in the lattice dimensions of mullite, by increases in the indices of refraction, and by changes in color. Ferrous oxide did not enter into solid solution with mute but reacted with it to form ferrous aluminate and ferrous silicate. The exsolution of ferric oxide from mullite also was studied. The results were applied to the explanation of the fired color of clay products and to the control of these colors. The effect of the solution and exsolution of iron oxide on the dimensional changes occurring during the firing of clay products was noted.
