Comparative studies of the effect of discrete surface hardening by standard ion-plasma technology and discrete oxidation technology on wear resistance have been carried out. Metallographic studies have shown that discrete oxidation has a polycrystalline structure. It was found that the technology of discrete oxidation makes it possible to increase the hardness by 31% in relation to the uncoated material, and the wear resistance of the cutting tool with oxidation is 1.5-3 times higher than that of the tool hardened by the standard ion-plasma technology.

Magnesium oxide wallboard - sheet construction and designing material based on magnesia binder. Magnesium oxide wallboards are mainly used as a construction substrate in the manufacture of building facades both in new construction and in repair of already constructed objects. One of the most significant disadvantages of this compound is low water resistance of articles, turn to cause corrosion in franked steel constructions.

The durability of buildings and structures is dependent on the quality of building materials and operating conditions. Clearly, during operation there may be adverse factors that were not considered on the design stage. These include a salt corrosion of the brick walls. It occurs reasonably often therefore the study of this subject is quite popular and important issue.

LEAN management is the concept of production management, product development and services that aims to create a true step change specifically targeted to the buyer or the goods or service. LEAN management is a dynamic process that uses knowledge and is focused on the customer. This is a process by which companies are continuously working to eliminate losses and value creation.
