Abstract

This article examines, using the theory of similarity and dimensionality, the surface of a part of bodies of revolution before plasma spraying of wear-resistant coatings, which plays an important role in activating the processes of bonding between the sprayed particles and the surface of the part. Physical processes of the interaction of the surface of the part before plasma spraying of wear-resistant coatings with a thermo-abrasive jet are considered. For physical and mathematical modeling, the following parameters were used: the average particle diameter, the average density of the material of the part, the density of the material of the particle, the path traveled by the particle, the initial velocity of the particle, the acceleration of the particle, and the impact strength of the metal, to reflect the process of motion of the abrasive particle in the thermo-abrasive jet. A regression equation was obtained, and the maximum energy of an abrasive particle, which will be supplied at an angle of inclination relative to the part, and the sum of particle velocities corresponding to these parameters, depending on the angle of inclination at the moment of impact, were determined.

耐磨涂层等离子喷涂表面的物理和数学建模

摘要

本文利用相似度和维数理论研究了等离子喷涂耐磨涂层前旋转体的一部分表面，这对激活喷涂颗粒与表面的结合过程起着重要作用。部分。考虑了在等离子喷涂耐磨涂层与热磨料射流之前零件表面相互作用的物理过程。对于物理和数学建模，使用了以下参数：平均粒径、零件材料的平均密度、粒子材料的密度、粒子行进的路径、粒子的初始速度、粒子的加速度，以及金属的冲击强度，反映磨粒在热磨料射流中的运动过程。得到了一个回归方程，磨粒的最大能量将以相对于零件的倾角提供，以及与这些参数相对应的颗粒速度之和，取决于此时的倾角影响，已确定。
