The mixtures HNO3-N2O4 are highly corrosive and attack metals (steel, aluminium or chromium, nickel). Corrosion can be inhibited by the addition of fluorine compounds, notably HF or PF [1]. The addition of 0.7 wt% of HF reduces the corrosion by a factor over 100 and the mixture of 44% N2O4 and 56% HNO3 with 0.7-1.0% HF termed standard HDA is in current use as a rocket oxidant fuel. [Pg.379]

RI examining showed that it could be reconditioned. However, another decision was accepted. It was decided to change the whole reactor compartment of this NS by the new one fabricated earlier. The motive for this decision was the following. In the course of this RI fabrication at the Machine-building plant in Podolsk there was faulty change of the SHS pipes fabricated from high-nickel corrosion-resistant steel by the pipes made from common stainless steel of the same size. [Pg.132]

The presence of hypochlorite in caustic is deleterious to nickel evaporators, forcing the oxidation of nickel to Ni(OH)2, HNi02, or HNiOJ. Chlorate has no influence on the corrosion rate of nickel, based on the data in Figs. 14.36 and 14.37 and the chloride-chlorate material balance around a caustic evaporator producing 50% NaOH. However, it has profound influence on nickel corrosion in anhydrous caustic concentrations. The reason for nickel corrosion in this system arises from the fact that chlorate decomposes above 250°C to chloride, releasing oxygen according to the reaction. [Pg.1343]

Plant tests show that the nickel corrosion rate can indeed be controlled very easily with addition of small amounts of NaBUt (Fig. 14.38). These tests also show that the NaClOs levels are unaltered in the presence of NaBH4, reiterating that NaClOs is not causal for the corrosion of nickel in 50% NaOH solutions. The beneficial effects of NaBHa addition toward suppressing the corrosion of nickel and other materials are presented in Table 14.11. [Pg.1345]

Nitrogen trifluoride gas is shipped as a compressed gas in steel cylinders and can also be provided by tube trailer. Metals suitable for use in NF3 systems at ambient temperatures are stainless steel, steel, brass, aluminium, copper, and nickel. Corrosion rates of less than 0.0025 mm/a at about 70°C have been measured for these materials [1,2]. However, the corrosion rate increases significantly in the presence of moisture or HF [2]. Fluorinated polymers such as Teflon, Kel-F, and Viton are not attacked by NF3 at ambient [1,2] and elevated temperatures [3]. These materials are recommended for flexible lines and fittings [1]. At elevated temperatures, where the reactivity is similar to that of fluorine, nickel and Monel are recommended as suitable materials for handling NF3 [1]. [Pg.182]

Experimentally determined impedance spectra of nanocrystalline nickel corrosion (fig. 20) are well mapped by equivalent electrical circuit with two time constants described by equation (5)... [Pg.415]

The equilibrium potential of the nickel-hydroxide electrode is slightly above that of water decomposition. In this respect the situation resembles that of the lead-dioxide electrode, but the much lower value of this potential allows the use of nickel as conducting element, since corrosion of this metal can be neglected, at least under normal conditions. For this reason, corrosion is not shown in Fig. 1.31. (Only in foam electrodes with an extremely large surface area of the substrate, nickel corrosion may slightly disturb the current balance in sealed cells.)... [Pg.104]
