It was found that the introduction of zirconium oxide as a modifier in an amount of no more than 10 wt % has a positive influence on the protective properties of the coating. There is no interaction between the alloy and the coating after heat treatment of the EP742 alloy coated at 1150°C for 2 h, and there is no oxidation of the alloy. Additional incorporation of graphite and silicon carbide into the coating composition decreases significantly the cooling rate of the samples. A heterogeneous large-porous structure increases the thermal insulation properties of the coating compositions. The study of lubrication properties of the coatings showed that the friction coefficient depends on not only the temperature and the degree of deformation, but also the coating composition to a significant extent. A friction coefficient decreases by 8–10 times with the use of protective coatings compared to those of uncoated EP742 alloy samples.

Under piezothermic conditions (application of high pressure and temperature to wet molding raw materials), the necessary chemical reactions, resulting in the formation of new lignin-carbohydrate compounds, are facilitated during the production of binder-free plastic (BFP) in a closed mold. Under these conditions, the high-pressure steam is generated, which impedes the molding material compaction and generates internal stresses caused by elastic deformations and compressed vapors and gases remaining in the material. Consequently, this leads to a decrease in the physical and mechanical properties of resulting material. This study examines the feasibility of using the “blow‑off” method to produce binder-free plastic by closed-mold pressing. A mathematical design of the experiment was used to conduct this study. As a result of the adopted experimental model, the BFP samples were obtained and the influence of filler moisture content and pressing conditions on their physical and mechanical properties was determined. Based on the resulting regression equation describing the process, the optimal BFP pressing conditions were determined using the “blow‑off” method. Samples based on pine and birch sawdust and sunflower husks were obtained and tested using the optimal factors.
