The cylinder liners used in locomotive diesel engines are subject to significant mechanical stress due to long-term operation under conditions of high pressure, temperature, and vibration. To meet power requirements for high torque and long-term durability in these challenging operating conditions, turbulence increases in the coolant passage channels on the outer surface of the cylinder liners where the flow direction changes or the channel geometry narrows. Local pressure drops in these areas can cause the liquid to fall below its vaporization pressure, leading to the formation of microscopic vapor bubbles. These bubbles that form in the regions where the flow reaches high pressure again suddenly collapse (implosion) and create very high temperature and pressure pulses locally [1], [2]. This impact effect causes deformations, microcracks, pitting, and material wear on the surface of the cylinder liner over time. The cavitation process that occurs in this way also significantly shortens the working life of the engine components. It also reduces the material life, reduces engine efficiency, and increases maintenance costs. Therefore, it is necessary to understand the working mechanics of locomotive diesel engines, which are characterized by high combustion pressures and fast piston movements, in detail and to evaluate suitable surface repair materials to prevent these effects.
