1表面致密化——一种提高烧结齿轮性能的有效方法显示文摘表面致密化与传统的粉末冶金方法相结合 ,可以显著改善烧结齿轮的疲劳及表面磨损性能 ,从而提高齿轮的寿命 ,同时使生产高性能齿轮的总成本降低 ,为用粉末冶金 (PM)方法生产汽车变速箱齿轮提供了更大的可能性。本文着重讲述了使用这种方法生产高性能PM齿轮的工艺过程 ,同时介绍了测定致密化效果及齿轮性能的几种主要方法 ,并根据工艺过程比较了使用传统的机加工方法及本文所述的方法生产同性能齿轮的成本差别。最后 ,以两个实例分别介绍了使用上述方法对Volvo 85 0系第五挡变速齿轮及Scania载重车变速箱中行星齿轮的研发。于洋 Linnea Fordén 2005粉末冶金技术2005,23,1:11
