When surfaces with anisotropic texture are moved in different directions related to their assembled counterpart during operation, the friction conditions change, as they determined by lay of topographies. In article, contributing exploration this characteristic, we analyze inhomogeneity topography on a face milled plane surface symmetrical setting sections at an angle 30° or 60° feed direction....

This work presents the results of tribological tests Mo and combined coatings TiAlC formed using electrospark alloying (ESA) technology additionally processed thermochemical electrolyte anodic heating (TEAH). ESA makes it possible to form 15–20 µm thick on friction surface, characterized by a high hardness wear resistance. Tribological studies were performed testing block-on-roll pair under 300...

At present, the common protection technology of power-transmission and transformation equipment is mainly coating hot-dip zinc protection. However, due to low adhesion epoxy zinc-rich coating, poor compatibility with top paint, environmental pollution, complex processing, high energy consumption other defects process, its development limited. In view above deficiencies, new anti-corrosion mater...

Abstract Wines are usually evaluated by wine experts and enthusiasts who give numeric ratings as well text reviews. While most classification studies have been based on conventional statistical models using variables, there has very limited work implementing neural network In this paper, we apply (CNN, BiLSTM, BERT) to extract useful information from reviews classify wines according different r...
