Abstract

Paint as an anticorrosive. Results depend on the preparation of the surface and on the quality of the paint. Investigations are described into the adhesive and weathering qualities of various materials, in particular of aluminium, exposing the test panels to both land and sea air. Degreasing and mechanical, chemical and electrolytical methods of cleaning the surface have been tried and compared and primers of a large variety have been tested. The primers consist of zinc chromates, phosphates and synthetics. Top coats of glycerophthalic, nitrocellulosic and other, for instance, fatty, combinations have been applied. Anti‐fouling paints have been applied to wood. It is shown that best results are obtained when the various treatments are harmonised.—(A. Guilhaudis and R. Bourbon, Revue de l'Aluminium, 1954, 31 (206), 7–11 and (207) 47–52.)

Abstract

In this article a resume is given of the principal obsevations made during the course of exposure in a natural atmosphere during some twenty years, while choosing the most characteristic examples. The following points will be examined: Resistance to spray and mist of aluminium‐magnesium, aluminium‐magnesium‐silicon, aluminium‐ zinc‐magnesium, and aluminium‐copper magnesium rolled alloys, and of cast alloys; Behaviour of welds, and of contacts with steel and cement; Behaviour during immersion in the sea, and corrosion by differential aeration; Protection by anodisation. These observations have been made during exposure at the experimental stations of the Pechiney Group, in marine atmospheres at Salin‐de‐Giraud (Mediterranean), Saint‐Jean‐de‐Luz, Biarritz and Ostend, and in an industrial atmosphere at Aubervilliers.

Abstract

THE alloys under consideration contain only zinc and magnesium as the major alloying additions. The total alloy content varies between 5 and 7 per cent whereas the high strength aircraft alloys have a total content of 8 to 10 per cent and may also contain up to 2 per cent of copper. A wide range of mechanical properties can be obtained with the weldable alloys and some of these properties closely approach those of the aircraft alloys. Problems associated with weld metal cracking and heat affected zone recovery arc normally severe with age hardening aluminium alloys but are greatly attenuated with the weldable alloys.

Abstract

Observations on alloy tests. Rotating‐cantilever tests in air and corrosion‐fatigue tests have been made on a high‐purity aluminium‐zinc‐magnesium alloy and on a commercial alloy (D.T.D. 683) in various conditions of heat treatment. The results are compared with special reference to the form of fracture and microstructure. Evolution of gas from active slip zones under corrosion fatigue has been observed.

Abstract

POSITIVE IONS The cause of corrosion? The authors have presented for consideration their observation that positive air ions seem to be the cause of corrosion. It was found that of two locations with identical climates one had positive and the other negative ions, and that the presence of the former caused corrosion. Associated with this finding was a considerable atmospheric conductivity.

Abstract

Leap forward in zinc‐rich paints. Corrosion Ltd. announce far‐reaching improvements in the whole of their range of Glopane zinc‐rich paints (otherwise known as ‘cold galvanising’ materials), as a result of the replacement of the normal type of zinc dust used for pigmentation by ultra‐fine zinc dust and improvements in media.

Abstract

Purpose

The purpose of this study was to determine the atmospheric corrosion behavior of aluminium (Al) exposed to the industrial and coastal environments of northeastern Arabian Peninsula for a period of 15 months.

Design/methodology/approach

The samples were exposed under atmospheric, underground and splatter zone conditions at the coastal region. Soil, groundwater, seawater and air particulate samples obtained from the exposure site were analyzed. Secondary electron microscopy was used to identify and study the microstructural features of the corrosion products formed at the surface of the test coupons. The corrosion rates of the samples were determined by the weight loss method.

Findings

The results showed that Al exhibited a moderate corrosion rate despite high degree of variation in temperature and humidity and large concentrations of chloride and sulfate in this region. Splatter zone environment was the most corrosive because of high chloride concentrations in seawater and the alternating wetting–drying cycles.

Originality/value

In this paper, corrosion of Al was evaluated in atmospheric, soil and splatter zone conditions along the northeastern coast of Arabian Peninsula and was also compared with the results of the test reported for other international locations.

Abstract

Before the pandemic, World’s public debt was considered excessive, mainly by the standards set by the IMF, the European Union and the euro zone. Today, with the pandemic COVID-19, the world economy is facing an economic crisis that only the public authorities can contain, at least in the short term. In France, the Arthuis Commission is proposing to control public debt and return to debt reduction by the end of this decade. However, the economic stakes go beyond the crisis caused by the pandemic. It is also a question of preparing a different society, one that is less unequal and capable of engaging in sustainable economic development in the face of global warming. The concern is more about the excesses of international financial speculation, growing social inequalities and living conditions on Earth, which threaten the economic and social future of new generations much more than public debt.

Abstract

The pandemic shock of COVID-19 had the indirect but powerful consequence of highlighting the limits of economic globalisation. National security not only is a military matter but also includes, more than ever, the sectors of health, education, industrial risks or the protection and availability of natural resources. States can no longer forget that products and services essential to human survival (food, medicines, and civil protection) must always be available within the country, either in stock or in immediate production capacity. The same applies to the control of vital technologies (especially digital). The power relations openly expressed in the military order being extended to the economic sector, as evidenced by the resurgence of economic sanctions. In the context of nuclear dissuasion, for the superpowers, it is no longer a question of obtaining mutual benefits through international exchanges; the will to weaken the power of the other becomes prevalent. At a time when the acceleration of major or more minor innovations is transforming the relevant spaces of socioeconomic regulation, particularly the nation-state, when the masses and financial flows are becoming uncontrollable, when the effects of climate change and the finiteness of natural resources should force us to reflect on the real sustainability of the dominant system of accumulation, logically implying determined cooperation, institutional innovations and more widely shared collective political visions, States that lack theoretical and practical tools are tempted to turn in on themselves. This paradox provides a breeding ground for new populisms and other forms of nationalism and radicalism.

Abstract

The crisis of globalisation and the rise of the COVID-19 pandemic pose new threats to the national security of all countries. States have been increasingly challenged on their role, particularly in the economic order. Their actions concerning pandemic, ecology, climate or air pollution have been strongly inspired by the decisions of specialised international organisations, too often advised by dominant commercial and financial interests. In this context, states have no longer been able to assume the full range of national security components. Mercantilists considered that dependence on a State’s foreign trade led to an unacceptable reduction to the power of the Prince. Today, all countries are dependent on others, and then economic wars are becoming more and more likely. Armed warfare between states remains a potential response to these possible disruptions of essential intermediate consumption or to the search for power. Moreover, the lack of solidarity perceived during the pandemic testifies to the maintenance of political and economic power relations between States and the priority given to national interests to the detriment of international public goods. The pandemic highlights the inability of states to find common solutions to today’s global problems, thus developing a strong sense of insecurity among citizens.
