Study of Wear of an Alloyed Layer with Chromium Carbide Particles after Plasma Melting

Antonina I. Karlina,
Yuliya I. Karlina,
Viktor V. Kondratiev
et al.

Abstract: Depending on operating conditions, metals and alloys are exposed to various factors: wear, friction, corrosion, and others. Plasma surface alloying of machine and tool parts is now an effective surface treatment process of commercial and strategic importance. The plasma surface alloying process involves adding the required elements (carbon, chromium, titanium, silicon, nickel, etc.) to the surface layer of the metal during the melting process. A thin layer of the compound is pre-applied to the substrate, then … Show more

“…The number of decision trees, the maximum depth of the tree, and the learning rate are the three key hyperparameters of XGBoost. In this paper, the search range of the number of decision trees, the maximum depth of the tree, and the learning rate are [50, 100, 200, 400, 500], [3,4,5,6,7,8,9,10], and [0.01, 0.05, 0.1, 0.15, 0.2], respectively.…”

“…If the process parameters are not appropriately chosen, excessive heat input can result in deformation, high residual stresses [7], poor surface quality, and splatter phenomena [8]. Karlina et al [9] emphasized the potential for optimizing process parameters to improve material characteristics. Thus, choosing the appropriate process parameter based on the deposition trajectory yielded by the slicing process is a critical step in the WAAM process.…”

“…Furthermore, the study suggests averaging results from multiple cropped EBSD datasets approximating the findings from larger datasets effectively, affirming the sufficiency of this combined approach for micromechanical modeling. Additionally, the studies conducted by Balanovskiy et al [23,24] and Karlina et al [25] show the important findings related to microstructure homogeneity and mechanical properties of AM materials, highlighting the potential for optimizing AM processes to achieve the desired material characteristics.…”

“…Selective Laser Melting (SLM) is an advanced manufacturing method that utilizes a high-energy laser beam to selectively melt and solidify metal powder within specific regions, thereby achieving "near-net-shape" fabrication of three-dimensional complex structures [1][2][3]. Based on the principle of "layer-by-layer" deposition and stacking, this technology enables direct fabrication of solid objects from digital models, offering advantages such as design flexibility, short production cycles, and cost savings.…”
