Сorrosion protection of metals: prospects of production and application of uralkyd materials (review)

Uralkyd oligomers are considered to be promising film-forming. They are widely used in the production of high-quality paints and varnishes for vari ous purposes (primeres, paints, priming-paints). The success of these materials is due to the high properties of coatings formed. These coatings have high adhesion, strength properties and corrosion resistance. The advanages of these materials is feed-stock availability, low cost compared to other polyurethanes, their usability. Uralkyd materials is one-component and low-toxicity system. So they are promising in the protection of various metal from corrosion. Uralkyd oligomers sufficiently versatile in use. They can be applied a lot of methods and combined with many types of paints (nitrocellulose, chlorinated rubber and oily alkyd oligomers). They can be used at the factory painting and refit painting of metal products

Influence of additives – oil tar modifiers on the oxidized bitumen adhesion to mineral materials

Petroleum tar was exposed to microwave irradiation or added with isopropyl alcohol and then oxidized to paving bitumen. The bitumen adhesion to mineral materials was investigated. Either of the two kinds of treatment enhanced the bitumen adhesion to marble chips and sand. The adhesion to the marble chips ran up to 5 points in contrast to 3 point of the sand adhesion magnitude. Addition of the alcohol to the tar promotes rise in alcohol benzene and benzene resins content in resulting bitumen to the greater exnent then the microwave irradiation which leads to reinforcing its bond with marble chips and sand

Research of Thermal Coatings of Composite Materials

Разработаны композиционные материалы на основе абразивостойких, антифрикционных и термореактивных порошков, которые образуют композитное антифрикционное покрытие, обеспечивающее необходимый уровень физико-механических свойств и эксплуатационных характеристик (износостойкость, пористость и прочность сцепления)

Research on wear resistance and friction coefficient of gas-thermal composite coatings with the addition of nano carbon components without lubricants

Сокоров И. О.; Ванюк Э. А.; Zadeh E. Ghazban; Куис Д. В.; Леванцевич М. А.; Лобко Д. Н. Исследование на износостойкость и коэффициент трения газотермических композиционных покрытий с добавкой наноуглеродных компонентов без смазочных включенийВ статье приведены научные исследования на износостойкость и коэффициент трения газотермических композиционных покрытий с добавкой наноуглеродных компонентов без смазочных включений. Установлено, что введение самофлюсующихся порошков с их последующим оплавлением снизило пористость покрытия в 2-3 раза, а коэффициент трения у композиции ПГ- 19М-01 с добавкой наноуглерода уменьшился до 50,8% по сравнению с этой же композицией без наноуглерода

Evolution of structure and phase composition of vacuum plasma coatings alloyed by aluminium

В статье представлены результаты исследования структуры и свойств покрытий, нанесенных из разделенных вакуумно-дуговых разрядных потоков на основе TiN легированных алюминием. Рассмотрено влияние элементного состава покрытий на структуру, фазовый состав и их механические свойства. Определили, что покрытия, содержащие в гексагональной фазе Ti[3]Al[2]N[2], характеризуются высокой твердостью, низким коэффициентом трения, максимальными значениями упругого восстановления и сопротивления пластической деформации
