Experimental Study on Surface Integrity of Titanium Alloy Machined by Prestressed Abrasive Belt Grinding

  • 摘要: 为了提高钛合金加工表面的抗疲劳性和抗腐蚀性,基于预应力砂带磨削原理,进行不同预应力条件(0、100 MPa和200 MPa)下的钛合金砂带磨削试验。通过检测、分析不同预应力条件下磨削后工件的表面完整性,获得不同预应力对工件表面残余应力、粗糙度、硬度及表面形貌的影响规律;并在砂带磨粒模型的基础上,揭示预应力砂带磨削对残余应力和表面形貌的作用机理。结果表明:在材料的弹性范围内施加预应力并进行磨削能够主动加强工件表面的残余压应力状态;随着预应力的增加,残余压应力的大小呈现逐渐递增的趋势;预应力砂带磨削对表面硬度的影响甚小,且在一定范围内不随预应力的变化而变化;采用预应力砂带磨削能够得到较好的表面形貌,但会使粗糙度有微量增加。
