“…The advantages of the water-oil-soluble inhibitor N-M-1 in comparison with the oil-soluble inhibitor FMT are confirmed by the data in table 2 standard corrosion tests of preservative formulations with these inhibitors. The obtained data of corrosion tests were compared with the electrochemical properties of the hybrid organosilicate coating OS-51-03M [11,12] with FMT, N-M-1 inhibitors and NOTECH surface preparation. Some results are shown in Fig.…”

A combined approach to paint was used to increase the effectiveness of anti-corrosion protection was used. In particular, passive insulating coating materials was modified with active additives. A water-soluble anodic inhibitor of atmospheric corrosion was encapsulated in a phosphate conversion coating NOTECH. As a result, the corrosion under a layer of paint primer was suppressed. It is important that phosphating does not create a layer like paint. So, such an approach is universal and compatible with most known types of paint coatings and can be combined with temporary protection (preservation). The second paint layer of the coating contained a water-oil-soluble corrosion inhibitor of the group “M”, namely: N-M-1. It is adduct of natural fat vegetable acids and cyclohexylamine. The data of corrosion tests and polarization curves are presented, which confirm the high protective properties of the proposed binary inhibitory anti-rust paint.

“…Due to a number of unique functional properties, organosilicate coatings (OSCs) are required for the nuclear power industry constructions [1][2][3], for instrumentation [4] and for anti-icing protection [5], including utilization in the Far North [6]. Among other applications, OSCs are used for the anticorrosion protection of bearing and enclosing constructions, reinforced concrete constructions and anchor bolts of railway contact network support foundations [7].…”

“…The polymer base fillers are finely dispersed silicates, organic or inorganic pigments, and various target modifiers (curing agents, plasticizers, etc.) [2]. During the welding, before the organosilicon polymer degradation, OSCs have properties that are generally similar to paints and varnishes, and after polymer base degradation, OSCs behave like high-temperature inorganic composite materials [11], which are characterized by valuable special qualities: heat resistance, radiation resistance, etc.…”

Composition of Organosilicate Coatings High-Temperature Breakdown Products and Their Distribution in the Weld

The construction assembly and the repair of steel constructions painted with protective coatings are often carried out using arc welding. During the welding process, the coating in the weld zone is degrading. The protective coatings breakdown products are involved in the pore and non-metallic inclusion formation in the weld, the composition and distribution study of which makes it possible to analyze the reactions occurring during the welding. In this study, welding beads were deposited on the coated sheet surface by MAG welding. The distribution of inclusions (the average diameter and the relative content) along with the porosity in different bead zones were investigated by optical and scanning electron microscopy and digital image processing, and the chemical composition of inclusions was determined using energy-dispersive X-ray spectroscopy. The amount of diffusible hydrogen in the deposited metal was estimated with the vacuum method. In this work, four organosilicate coatings grades, differing in their purpose and heat resistance, were used, and their effect on the weld was studied.
