Title: Zinc-chromium composite plated steel sheet excellent in spot weldability
Inventor: ANDO SATOSHI
IPC: C25D5/26
Filed: 1995-05-31
Abstract: PURPOSE: To provide a stable and prolonged electrode life and a plated steel sheet without performing complicated treatments, such as addition of iron group elements and multilayer formation, by controlling the amount of Cr oxides in a plating film. CONSTITUTION: In a Zn-Cr composite plated steel sheet having a Zn-Cr plating film, the total amount of Cr oxides in the plating film is regulated to <420mg/m<2> (including the case of zero). When the Cr oxides exist by >=420mg/m<2> in total in the plating film, the resistance of the plating film is increased, and heat generation in the plating film at spot welding is increased. As a result, the melting time of the plating layer at welding is prolonged and the wear of the electrode is rapidly advanced. Accordingly, by controlling the total amount of the Cr oxides in the plating film to <420mg/m<2> , a stable and prolonged electrode life can be obtained and also the Zn-Cr composite plated steel sheet causing neither sparking nor deposition at welding and having excellent spot weldability can be obtained.
