摘要
刀具的损坏形式主要有磨损和破损,研究发现,磨损损坏形式在刀具损坏中的比例高达70%。为了减缓和降低刀具的摩擦强度,延长并提升刀具寿命,本文基于仿生学原理,通过纳秒激光器在刀具表面加工沟槽织构,改变刀具表面的结构和形态。探究激光参数对微织构尺寸和形貌的影响,确定加工微织构的最优激光参数。在此基础上,分析干摩擦条件下不同面积占有率的正弦型沟槽织构刀具在不同载荷和摩擦速度条件下的减摩机理。
The main forms of tool damage are wear and damage.It is found that the proportion of wear and damage in tool damage is as high as 70%.In order to slow down and reduce the friction strength of the tool and prolong and improve the tool life,based on the principle of bionics,the groove texture on the tool surface by nanosecond laser to change the structure and shape of the tool surface is processed.The influence of laser parameters on the size and morphology of micro texture is explored,and the laser parameters for processing micro texture is determined.On this basis,the friction reduction mechanism of sinusoidal groove textured tools with different area occupancy under dry friction conditions is analyzed under different load and friction speed.
