    The Influences of Wear Debris on the Fretting Wear Behavior of Inconel718 Laser Cladding Alloy Layer by XU Zhibiao, XIE Sen, WANG Xiaoyi, LI Dexiang, LYU Xiaowen

    Published 2024-10-01
    “…Fretting wear is a material damage phenomenon caused by small vibrations between tightly contacting surfaces.Studying the role of debris in fretting wear is of great significance for revealing the damage evolution of materials during fretting wear.In this work, a fretting wear test was conducted on Inconel718 laser cladding alloy layer using ball/plane point contact method on a multifunctional friction and wear testing machine.After the experiment,the mechanical dynamic characteristics during fretting wear process are obtained by analyzing the Ft-D (friction displacement) curve and COF (coefficient of friction) curve.In addition, scanning electron microscopy (SEM) and three-dimensional profilometer (3D) were used to analyze the damage morphology of the contact interface and reveal the main damage mechanism of micro motion wear.The particle size distribution calculation software (Nano Measurer) was employed to statistically analyze the particle size distribution of abrasives.Results showed that the particle size of abrasive debris is mainly distributed between 1~3 μm, and the magnitude of displacement amplitude was positively correlated with the speed of debris discharge.At large displacement amplitudes, the size of the debris was relatively large,which could easily cause abrasive wear, while at small displacement amplitudes, debris was prone to accumulate and hinder the progress of wear.Moreover, under high normal loads, the generation of debris accelerated and exacerbated surface damage to the specimen, with fatigue wear and abrasive wear playing a dominant role.Under small normal loads, debris could reduce the friction force and friction coefficient.In addition, the removal of debris would not change the fretting regime.…”

    Comparative genomics of Botryosphaeria dothidea and B. kuwatsukai, causal agents of apple ring rot, reveals both species expansion of pathogenicity-related genes and variations in... by Bo Wang, Xiaofei Liang, Mark L. Gleason, Rong Zhang, Guangyu Sun

    Published 2018-12-01
    “…Botryosphaeria kuwatsukai contained significantly more transposable elements and higher value of repeat induced point (RIP) index than B. dothidea. Our results will be instrumental in understanding how both phytopathogens interact with their plant hosts and in designing efficient strategies for disease control and molecular breeding to help ensure global apple production and food security.…”
