Patent number: 9945020Abstract: Provided is a zinc-plated steel sheet for hot pressing having outstanding surface characteristics, comprising: a steel foundation plate comprising a metal surface diffusion layer of which the Gibbs free energy reduction per mole of oxygen during oxidation is less than that of Cr, an aluminum-rich layer containing at least 30 wt. % of aluminum formed on the surface diffusion layer, and a zinc plating layer formed on the aluminum-rich layer. In this way, a metal having a low affinity for oxygen is coated to an effective thickness prior to annealing and thus the creation of annealing oxides at the surface of the steel sheet is suppressed and a uniform zinc plating layer is formed, and alloying of the zinc plating layer is promoted during press-processing heat treatment. Cracking in the steel foundation plate during hot press molding is prevented.Type: GrantFiled: May 4, 2015Date of Patent: April 17, 2018Assignee: POSCOInventors: Il-Ryoung Sohn, Jong-Sang Kim, Joong-Chul Park, Yeol-Rae Cho, Jin-Keun Oh, Han-Gu Cho, Bong-Hoon Chung, Jong-Seog Lee
