Academy of Railway Sciences modern transportation methods were studied parts for wear and damage mechanisms in use in the

According to improving the life and efficiency of the diesel locomotive engine topics task, the All-Russian Scientific Research Institute of Railway Transport mechanism using modern methods of research parts wear and tear in the use of research to improve the success of friction wear resistance and strength of parts methods.  Stainless steel needle valve  the cylinder piston set of parts is not fixed under thermal conditions, load and speed conditions, lack of oil and gas medium abrasive media and the role of work, and this causes the diaphragm to rupture and working  Instrument valve manifolds  degrees of damage occurring micro-adhesion. Often occur in the thin surface layer is brittle and the irreversible processes, and fatigue damage to the friction in the region of solid particles falling from the engine oil caused by airway channel, but also to promote the occurrence of such a situation. Induce protective film rupture temperature of solid abrasive particles and the friction contact area, and microstructure by external factors occurs strongly adhesive wear has the greatest impact.
