Opis:
The phenomenon of atmospheric corrosion of metals causes significant economic losses in the economy of most developed countries. In order to reduce them, many methods have been developed that use physical phenomena and chemical reactions to protect metal surfaces against corrosion. One of the methods that use the phenomenon of physical protection is temporary protection of metals with lubricants, i.e. plastic greases and lubricating-protective oils. Plastic greases are characterized by a very high kinematic viscosity and create tight and thick protective layers on the surface of metals. Protective oils intended for temporary protection are designed to create a tight, thin, well-adhering protective layer on the metal surface. Temporary protection of metals against corrosion with protective oil consists in covering the metal surface with easily removable lubricants, whose task is to create a tight protective layer separating the surface of the protected metal from the adverse effects of weather conditions. Temporary metal protection is also used in the case of corrosion protection of intermediates between production stages, and in the case of finished products, e.g. during storage and transport. One of the most important features of protective oils is the formation of a thin protective layer on the metal surface to separate the metal surface from the surrounding air. This protective layer is produced by protective oils of low kinematic viscosity. Due to the lack of any requirements for operational tests for protective oils in real conditions, an attempt was made to develop such a methodology and verify it by conducting a field test. The article describes a method of testing the effectiveness of metal protection against corrosion in field conditions. The method of preparing the surface of selected elements for corrosion protection and the method of applying a protective layer on metal plates of a simple shape and with a complex surface shape are described. The description of the test stand as well as the method of selecting the places of exhibition are included. The results of the conducted study are presented. The obtained test results are of an application nature.

Opis:
Corrosion of metals is the gradual destruction of metal under the impact of environmental factors. Chemical or electrochemical processes on the surface of the metal cause irreversible changes in the structure of the metal. To prevent this, during storage or transport, the surfaces of metal elements must be protected against environmental factors, which include: high air humidity, acid rain and variable temperature. These factors accelerate the corrosion process, which cannot be eliminated, but can be reduced by protecting metal elements with e.g. protective oils. Some metals have the ability to passivate, which is a natural protective agent that prevents corrosion. It consists in the formation of an oxide of this metal on the metal surface. Where there is no natural protection against corrosion, protective measures must be used. This paper presents the technology for the production of protective oil for temporary protection against corrosion. The innovation of this project is that the oil will form a thin, well adhering protective layer on the metal surface, which can be easily removed. It is characterised by very low viscosity and low dripping time. It is possible to achieve by using proper base oil with carefully selected anti-corrosion additives. Based on the standard PN-75/C-04154 Petroleum products. Rust protection by metal preservatives the humidity cabinet test method, corrosion tests were carried out. The paper presents the results of a humidity cabinet test for an oil mixture based on deeply refined base oil and properly selected refining additives. The test results confirmed very good anti-corrosive properties of the developed oil due to the use of a corrosion inhibitor and an oxidation inhibitor. The thickness of the protective layer formed on the metal surface was calculated based on a mathematical formula. The resulting layer forms a thin oil film, easy to remove and protecting the metal surface from corrosion.
