Study on the Friction Reduction and Wear Resistance Performance of the Surface Laser Micro-texture Shape of the Chain Pin of Marine Engines
Due to the complex marine environment, ship engines are under the harsh working conditions of high humidity and high salinity for a long time, which seriously aggravates the frictional wear of engine chains and thus affects the working stability and the fatigue life of engines. Based on this, this s...

| description | Due to the complex marine environment, ship engines are under the harsh working conditions of high humidity and high salinity for a long time, which seriously aggravates the frictional wear of engine chains and thus affects the working stability and the fatigue life of engines. Based on this, this study designs the surface textures on the chain pin in three shapes—square, sine and circular. Combining experiments and simulations, the influence of texture shape, area occupancy and depth on the friction and wear resistance is studied in order to provide new ideas and theoretical basis for solving the long-term engine chain wear problem. The results show that the presence of the texture reduces the elemental Cr content of the surface after wear and thus improves the surface wear resistance compared to a smooth no-texture surface. Among the three texture shapes, the sinusoidal texture exhibites the best friction reduction and wear resistance performance, and the highest friction reduction rate of about 31. 9% is achieved under high speed and light load conditions. The sinusoidal texture has the shallowest surface wear marks, and the wear process is mainly micro-motion wear, accompanied by slight adhesive wear. |
