喷丸时间对GH4169合金表层组织及性能的影响
|
摘要
利用2mm不锈钢弹丸对GH4169合金表面进行高能喷丸处理,研究喷丸时间对合金表面形貌、表层显微组织、表面粗糙度和显微硬度的影响。结果表明,随着喷丸时间延长,喷丸作用层厚度、显微硬度、表面粗糙度都随之增加;当喷丸时间为10min时,GH4169合金的喷丸作用层厚190μm,表层显微硬度(HV)为389,较原始试样提高了35%。
High energy shot peening was used to treat the surface of GH4169 alloy with 2 mm in diameter stainless steel projectile.The effects of different shot peening time(1 min,3 min,5 min and 10 min)on the surface morphology,surface microstructure,surface roughness and microhardness of the GH4169 alloy were investigated.The results reveal that the surface integrity of the alloy is decreased with the increase of the shot peening time,while the shot peening layer,the microhardness and the surface roughness are increased with increasing in shot peening time.With shot peening for 10 min,the thickness effect of shot peening layer of GH4169 alloy can reach 190μm,and the surface hardness is 389 HV,increased by 35% compared with that of the original sample.
