摘要
分析研究了灰铸铁凸轮轴经氩弧重熔工艺处理后，约５０００ｋｍ 正常行驶后个别轴局部区域出现早期麻点与部分剥落而失效，结果证明早期失效的原因为氩弧重熔工艺不稳定所致。
This paper studied the causes of the early stage pitting on local areas and peeling off after 5000km drive in some grey cast iron camshafts which were treated by argon arc remelting.The analysis result showed that it was because of the unstable argon arc remelting process.
