摘要

分析了内燃机曲轴的工作条件、主要缺陷和修复技术，包括电弧堆焊、气焰堆焊、爆轰堆焊、等离子堆焊等各种堆焊和喷涂工艺，等离子堆焊又分为感应堆焊和等离子堆焊。值得注意的是，与新零件相比，硬度比（НRСr/НRСn）和疲劳强度极限（G-1r / G-1n）数值大于1的零件修复技术可以更好地满足可靠性指标。同时，没有一种修复技术完全满足这一指标，因为在大多数情况下，新曲轴的耐磨性高于修复零件。使用各种方法应用的抗摩擦、耐磨和固体润滑剂涂层，包括精加工抗摩擦非磨料处理（FANT），增加了抗磨损、抗腐蚀和抗疲劳性，并改善了摩擦机部件的磨合。

An Analysis of the Physical and Mechanical Principles of Crankshaft Reconstruction

The paper presents an analysis of operating conditions, main defects and restoration technologies for internal combustion engine (ICE) crankshafts including various types of surfacing and spraying such as electric arc, gas flame, detonation, and plasma which is subdivided in turn into induction and plasma-arc processes. It is noted that reliability metrics are better met by technologies for restoring parts with hardness ratios (НRС_r/НRС_n) and the fatigue strength limit (G_–1r/G_–1n) numerically greater than one compared to new parts. At the same time, none of the restoration technologies fully satisfies this indicator because the wear resistance of new crankshafts in most cases is higher than that of restored parts. The use of antifriction, wear-resistant and solid lubricant coatings applied by various methods, including finishing antifriction non-abrasive treatment (FANT), increases the resistance to wear, corrosion, and fatigue and improves running-in of rubbing machine parts.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
