摘要：

A sequential method is adopted to estimate the surface absorptivity in the process of laser surface hardening in this paper. The experimental temperature data given by Wang et al. [8] is used to verify the applicability of the proposed method. The results indicated that the proposed method is able to estimate the surface absorptivity accurately in the process of laser surface hardening. (C) 2015 Elsevier Ltd. All rights reserved.
