摘要

通过设计不同磨削工艺参数组合，研究了定向凝固高温合金IC10在缓进给磨削过程中表面完整性的变化，分析了IC10合金在缓进磨削过程中工艺参数对磨削表面粗糙度、显微硬度、三维形貌、显微组织的影响规律。研究表明：IC10合金在缓进给磨削过程中，当砂轮线速度v

在15~20m/s之间变化，工件进给速度v

不大于200mm/min，磨削深度a

不超过0.5mm时，可以获得较好的表面质量。另外，IC10在缓进给磨削过程中会产生较严重的加工硬化现象，硬化程度最大可达26.9%，最大硬化层深度可以达到230μm。同时，IC10 在缓进磨削过程中沿磨削深度方向上会产生表面白层和塑性变形层，其深度分别在0.24~3.2μm 和0.48~3.8μm 之间变化。

Abstract

Different combination of grinding process parameters are designed to research the surface integrity of IC10 directionally solidified superalloy in creep feed grinding. The effects of process parameters on the surface roughness

surface topography

microhardness and microstructure alteration of the subsurface are investigated in detail. The results show that a better surface quality can be obtained during creep feed grinding of IC10 superalloy under the conditions: the wheel speed ranges from 15 to 20m/s

the workpiece speed is not more than 200mm/min

and the grinding depth is not more than 0.5mm. In addition

surface hardening phenomenon appears on the ground surface

the maximum hardening degree can reach 26.9% and the maximum depth of the hardened layer is 230μm. At the same time

the white layer and plastic deformation layer are produced in the subsurface

the depth of the white layer and deformation layer ranges from 0.24μm to 3.2μm and 0.48μm to 3.8μm respectively.
